Introduction

This chapter is divided into 5 sections:

Stand delineation tools

Central review process

Definition of terms

The basic building blocks of the inventory are compartments and stands.

Compartments

State-owned forest lands are arranged

into blocks of land called

Compartments. A compartment is

simply a (usually) contiguous portion

of the state-owned lands in a

management unit. Use of

compartments provides a convenient

reference to location. Compartments

were developed to:

Summarize data and

recommend treatments on

an area small enough to allow quick visualization of existing conditions

and the effects of treatments.

Systematically examine and treat large forest acreage.

Disperse treatments spatially over the Forest Management Unit.


Help assure a more uniform acreage of treatments by cover type in

each year.

Compartments are generally between 1500 and 3000 acres. Smaller

compartments may be necessary in areas of broken ownership or when

management objectives are more readily met with smaller compartments.

Larger compartments may be desirable when management objectives call for

large acreage of forest cover for specific goals (e.g. sharp-tail grouse

management, kirtlands warbler management, wild or natural areas, etc.).

Stands

Compartments are broken further into stands. A

stand can be defined as a polygon representing a

relatively homogeneous area of a similar cover type a

contiguous group of trees sufficiently uniform in age-

class distribution, composition, and structure to be a

distinguishable unit.

Forested Stands Tree canopy covers at least 25% of the

stand.

Nonforested Stands Tree canopy covers less than 25%

of the stand.

Note: Nonforested stands now include stands

that may have a FORESTED management

objective, but where regeneration (artificial or

natural) is not yet large enough to have a

canopy that shades 25% of the ground

(e.g.- young plantations or recently harvested

sites).


Year of Entry (YOE)

All compartments are assigned an entry year based on a ten year cycle. Entry

years are fiscal years and the YOE represents the fiscal year that treatments will

be initiated.


Compartment Boundary Creation and Verification

The Compartments database within the GDSE is our best representation of

State Forest, State Game Area, and State Park lands. Before inventory of any of

these lands can begin, the boundary within this database must be corrected and

verified. In the IFMAP inventory process, there is increased importance on

correcting the compartment boundary BEFORE stand data collection begins.

The verification of compartment boundaries and creation of a Pre-Inventory layer

for a compartment is a joint effort between the Resource Assessment Unit (RAU)

in Lansing and the Forest Management Units (FMU) throughout the state. As the

figure below demonstrates, communications must be iterative flow both ways

to be successful.

This process begins with the stand examiner communicating with the RAU about

any inaccuracies within or adjacent to the compartment(s) to be inventoried.

Communication back and forth (emails, phone calls, annotated ArcMap projects,

etc.) should occur until the boundary is finalized. Both are responsible for the

quality of the final product. When contacting RAU, the unit staff should contact

the RAU forest compartment mapping Analyst assigned to their FMU.


In addition, RAU ensures that adjacent compartments fit together, making sure

that changes in one compartment mesh with the adjacent boundaries of other

compartments.

Compartment boundaries should be verified and corrected based (in

order of preference) on:

In the event a survey corner can be located visually using rectified

digital aerial photography, compartment boundaries will be based on

the corners as seen on the imagery. Utilize the latest imagery

whenever possible. Leaf-off imagery is often the best tool for this

task.

Example: Corner originally thought to be in center of road. Examiner

found actual corner monument in center of opening. Compartment

boundary moved by RAU.

GPS corner locations will be used where applicable and data was gathered with suitable equipment. Consult with the GPS committee for standards.

If GPS corner locations are not available, and other evidence does not

exist for locating the compartment boundary, the quarter-quarter

sections have been used in the Compartments layer. The quarter-

quarter grid is a geographic grid system developed from breaking

down sections into 40 acre parcels. A mathematical formula was used

to automatically create the parcels from the one mile-square sections.

The sections were developed from the original survey completed

throughout the state of Michigan in the 1800s.

If a boundary can be determined visually using rectified digital aerial

photography, compartment boundaries will be created using the


boundaries as seen on the imagery. This includes features such as

previous harvest lines, adjacent farm fields, and other features. These

boundaries are only to be used in the absence of other locations as

noted above.

If a compartment boundary follows a geographic feature (road, river,

lake, etc.), the centerline of the geographic feature will be used as the

boundary. If the road or river falls on a private boundary, the

property description shall be used.

Meandering lakes shall be repositioned similarly to the other base

features using the most recent imagery covering the entire area of the

lake in question.

After the boundaries are approved by the unit, and the RAU has created the

initial Pre-Inventory layer for the compartments to be inventoried, the Stand

Delineation Process begins.


Stand Mapping Rules

What is a Stand?

Stands, as defined earlier in the chapter, are polygons representing a

relatively homogeneous area of a similar cover type. This is different

from past inventory systems used in Michigan (such as Operations Inventory) in

that treatments past or future are not part of the definition. Stands should

not be delineated base on management objective, or the next potential period of

treatment. Stand boundaries are different from proposed and approved

treatment boundaries, which are different from actual treatment boundaries.

One size doesnt fit all. Final cover type boundaries can and will be different

from treatment boundaries created later in the process.

Mapping Unit Sizes

IFMAP is an inventory of cover types. Any inventory must have rules of inclusion

and exclusion. Mapping unit size and multi-poly rules have been developed to

meet DNR needs of quality, efficiency, and consistency. Features that do not

meet these rules must be merged into adjacent stands. Noteworthy

landscape elements that do not meet the minimum mapping rules should be

identified with the Opportunistic Field Survey (OFS) tool.

RULES:

All areas that are forested, and of similar species composition and size class that are larger than 5 acres (measured in ArcGIS as at least 4.51

acres), must be mapped. Similar species composition is defined as

continuous areas of the same level 4 cover type.

All areas that are Non-forested, and of similar species composition (continuous areas of the same level 4 cover type) that are larger than

1 acre (0.951 acres), must be mapped.

Forested stands less than 5 acres (4.51 in ArcGIS), and Non-forested stands less than 1 acre (0.951 acres) cannot be mapped unless they

meet one of the exceptions below.


Exceptions:

1. Inclusions forested cover type polygons down to 1 acre (measured in

ArcGIS as at least 0.951 acres) may be delineated as a stand if the

adjacent stands differ in either of the three following ways:

a. Adjacent stands with different cover type calls at:

Uplands at least a level 2 difference (e.g. pine

vs. oak, which are level two cover types upland

coniferous vs. upland deciduous, or forested vs.

non-forested)

Lowlands level 3 difference (actually the same

level difference, but level 3 due to naming

conventions)

b. Adjacent stands different by 2 classes at canopy closure.

The canopy closure classes are 0-25%, 25-50%, 50-75%,

and 75-100% (e.g. 25-50% vs. 75-100% closure).

c. Adjacent stands different by 2 classes in size class (e.g.

sapling vs. log stands).

2. Split stands if compartment lines (state land on both sides of line) split

a feature that in total meets minimum mapping size rules, the stand in

the current compartment may be less than the minimum mapping rules.

3. Isolated parcels (small ownerships) may be less than minimum

mapping rules by necessity.

4. Linear features

Roads, Power lines, and Pipelines need a minimum width of 12 meters

(40 feet) to be mapped as a polygon. All roads will also be line

features on the transportation layer.

Rivers and Streams need a minimum width of 15 meters (50 feet) to

be mapped as a polygon.

Multi-poly stands The general definition of a stand is a polygon

representing a relatively homogeneous area of a similar cover type.

There are times when a homogeneous area of a similar cover type may


consist of multiple polygons that are not directly adjacent. In most cases,

those should be treated as separate stands. The rules described below

were developed to accommodate those limited situations that arise

because of management history. The most common situations where

multi-part polygon stand rules apply include (but are not limited to): strip

plantations, smaller adjacent young stands (5-spot or patch harvests),

and stands that are split by map-able artificial boundaries like roads or

rivers. In order to accommodate the use of multiple polygons that are

indeed the same stand, such as strip plantations, rules have been

developed. The individual polygons of multi-poly stands are subject to

the same minimum mapping sizes as inclusions.

Here are a few situations where multi-polygon stands may be used:

Forested Stands:

a. Past Management Influences. Under this exception, two or more polygons can be considered the same stand if all of the

following apply:

Have the same documented (planting record, disturbance,

stocking survey, or cut record) year of origin.

Appear to have the same tone and texture in imagery.

Be no more than one tenth mile apart from edge to edge.

No more than one of the polygons may be larger than 10 acres

(In other words, if one of the multiple polygons being

considered for a multi-polygon stand is larger than 10 acres,

then the others must be smaller than 10. Otherwise, two or

more stands should be made.)

Multi-poly pieces are subject to the same minimum mapping

sizes as inclusions.

Note: This is meant to be used in a very limited fashion for

specific treatment-caused conditions such as strip plantations

and spot harvests.

b. Split by map-able features. For this second situation, all of the following must apply:

Appear to have the same tone and texture in imagery

Be separated by a delineated pipeline, power line, river, stream,

ditch; or roadway.


They must have a documented year of origin within 10 years

(closer is preferred) in all polygons from planting records, cut

records, or multiple recent documented increment bores (OR

both are truly uneven-aged as defined).

Non Forested Stands

a. Split by linear map-able features. For this situation, all of the following must apply:

Be separated by a delineated pipeline, power line, river, stream,

ditch; or roadway.


b. Be a linear stand that is split by ownership. For this situation, all of the following must apply:


Be separated by a break in ownership.


Stand Delineation Tools

After the compartment boundaries are approved by the stand examiner, the RAU

creates the initial pre-inventory layer and the FMU examiner does initial stand

delineation. The examiner may make modifications (edits) to that delineation on

throughout Stage 1 data collection, ending with the final stand boundaries

when field work is complete.

Overview of Stand Delineation Procedure

What follows is brief overview with recommended procedures within the IFMAP

GDSE for completing stand delineation. The sections following will go into greater

detail on each step or tool referred to in this overview.

1. The first time you enter a compartment for stand delineation, select Open a

Template after logging in. Choose the template on the IFMAP tab labeled

Pre-Inventory Stand Delineation.mxt.

2. To begin digitizing, start an edit session (see Appendix Z). Choose the

correct GIS database (that includes the Pre-Inventory layer), and set the

selectable layer to the Pre-Inventory Stands layer (on the Selection tab in

the table of contents).

3. Delineate any additional long linear features. Use the Split or Line-Cutter

Buffer tools.

4. Delineate stand island features. For islands within islands (think

doughnuts), digitize the outside island first, then smaller islands within it.

5. Delineate the remainder of the stands.

6. After each delineation (or after entire compartment is delineated):

Verify that the stand meets minimum mapping sizes.

Fill in forested/non-forested on the data entry form.

For non-forested stands, fill in the cover type code.

7. Save edits often during digitizing sessions. Saving the document (.mxd)

does not save edits to stands! Use the save edits command.

8. If you would like to use your document to continue work in the future, save

the .mxd into your home directory (M: drive in the GDSE).


Edit Tools

For stand delineation, the GDSE uses only 4 basic edit tools available by

selecting the Pre-inventory toolkit:

Split - splits an existing polygon into two polygons by drawing a

line across the original polygon.

Island creates a polygon within an existing polygon that does not

share in the original polygons border.

Merge merges existing polygons into one.

Explode explodes a multi-part polygon into its constituent parts.

In addition, two other edit tools are available in the Pre-inventory toolkit:

Burn-In polygon - This tool can be used to delineate stands that

may have been missed at first and now need to be identified, but

intersect multiple existing stands. It saves the steps of multiple

stand splits and merges.

Line Cutter Buffer delineates long linear features that bisect a

compartment and have a consistent width (roads, power lines,

etc). It can also be used to burn-in a new stand through multiple

existing stands.

If users follow the recommended procedures, these 6 tools can create or undo

any stand configuration. By only using these 6 tools, creation of slivers and

other unwanted conditions is minimized.

Tip: Remember to turn off the imagery when panning and zooming. Keeping

imagery off as a default will speed up drawing time considerably.

Long Linear features Use of the Split or Line Cutter Buffer tool.

As noted, the Split tool splits an existing polygon into two polygons by drawing a

line across the original polygon.

Since these features will share a common boundary with many other stands,

they should be delineated first. Typically, these features will be created by using

the split poly tool. If the stand maintains a VERY consistent width, you may use


the Line-cutter buffer tool and specify that width and the side of the line that

should be buffered.

1. Using the Imagery, locate any long skinny stands.

Zoom to a scale that allows you to see the entire

length of the stand.

2. Start Editing. Select the Pre-Inventory toolkit, and

set both the selectable layer and target layer to

the Pre-Inventory Stands layer.

3. Select the polygon that needs to have a long stand punched into it by using

the Editor Arrow or the Select Feature

Arrow . Only one polygon can be cut (split)

at one time. If several polygons are selected, a

message box will inform the user that user has

multiple selects and must only have one poly

selected. If no polygons are selected a message

will pop-up informing the user that they must

first select a stand before using this tool.

4. Click the Split Polygon icon.

5. To cut the polygon, the split line must start and end outside of the

polygons boundaries. Use the pencil tool on the Editor menu to

delineate (it should default to this). Click once at the end of each

vertices (portion of the line) when you change direction; then

double-click (or Right-click>Finish sketch) to end the line. The line

must cut the polygon completely into two sections; therefore the

split line cannot end in an island of the same polygon. The split line

can go through other polygons but will not cut them.

TIP: In order to split long linear features, the screen must be

zoomed out to see the entire length, yet this may not be the best

scale to allow placement of each vertices correctly. ArcMap allows

use of zoom tools in mid-digitizing stream. Use the zoom-to tool

to zoom in. When the delineation needs to move beyond the extent


of the zoomed in display, use the vertical and horizontal slider bars along the

side and bottom of the View window to pan to the next segment of the

delineation.

6. As soon as you end the line (double click), a

message appears that tells you the application

is splitting polygon please wait. The stand

will be split into two numbered polygons and

the attribute editor appears, listing showing

both stands. More information on the

attribution editor is

provided further in this

chapter.

7. If this is the first line of a

long polygon, dismiss (click

the in the upper right corner) the attribute editor and

repeat steps 3-6 for the other side of the polygon.

8. If this stand was missed at first, and existing stands were

digitized that crossed this line, its possible to use the

Line-cutter buffer tool to burn-in a new stand that has a

consistent width.

Creating Stand Islands

Many stands will not at least initially share boundaries with adjacent stands.

These are island polygons.


The Island tool creates a polygon within an existing polygon that does not share

in the original polygons border. To digitize island stands:

1. Using the Imagery, locate an island stand. Zoom to a scale that allows you to

accurately digitize the stand.

2. Start Editing. Select the Pre-Inventory toolkit, and set both the selectable

layer and target layer to the Pre-Inventory Stands layer.

3. Select the polygon that needs to have an island stand punched into it by

using the Editor Arrow on the Editor Toolbar or the Select

Feature Arrow on the IFMAP Toolbar.

4. Click the Create Island Tool from

the Pre-inventory Toolkit Menu Bar. A

message box appears instructing you to

digitize the island. (If no polygons are

selected, the tool will instruct the user

to first select a polygon.)

5. Click Ok and, using your mouse, delineate the stand. Double-click to finish

the sketch. Sometimes Citrix has difficulty recognizing a double click action

in that case, right click and select the Finish Sketch option.

Delineation of a Stand Island Polygon

6. In the attribution form, select whether the new island is Forested or Non-

Forested.


7. Clear the selected feature by either pressing the deselect button on the

IFMAP toolbar or clicking outside of the pre-inventory stands layer.

8. Repeat this process of Stand Island delineation for all island stands, saving

edits often.

Creating the rest of the Stand Polygons

After creating the island stands, the rest of the stands can be digitized using the

split polygon tool (see instructions above).

Completed stand delineation for the compartment polygon

Using the Merge Stands Tool

Throughout the process, you may want to delete a digitized stand by merging it

back into an adjacent stand. The merge process is:

1. Using the Imagery, locate the stand you wish to merge. Zoom in to a scale

where you can see both the merge-to (parent) and the merge-from

(child) stands AND read their pre-inventory stand number labels.

2. Start Editing. Select the Pre-Inventory toolkit, and set both the selectable

layer and target layer to the Pre-Inventory Stands layer.

3. Select the parent stand the attributes from this stand will be the stand

attributes after the merge. The attributes of the child stand will be lost. The

merge tool will not operate if multiple stands are selected.

4. Select the Pre-Inventory Toolkit and click Merge Stands .


5. A form appears. Select the stand

number of a polygon that you

want to merge into the selected

stand.

6. Once you have chosen the stand to merge, the second stand will be

highlighted on the map. When you click the Merge button, the tool will

combine the stands and the custom attribute editor will appear. Attributes

from the first stand selected, or the parent stand, will be retained by the

new merged stand.

TIP: To create multi-poly stands, first verify that the situation fits the mapping

rules for multi-poly stands earlier in this chapter. Merge non-adjacent polygons

into multi-poly stands, using the same techniques shown under Using the Merge

Stands Tool above.

Explode tool

There are cases when the delineator must unmerge or explode stands. For

example, a group of polygons that seemed to be identical from the imagery

actually has very different characteristics.

To explode a stand into its constituent parts, select the stand you wish to

explode and click on the explode tool. The stand is split into individual

polygons with identical attributes. Update individual stand attributes as needed.

Burn-In tool

The burn in tool is one of the newer IFMAP delineation tools that have been

developed. It was primarily built for use with other data layers (e.g.-

Treatments, etc), but can be used in Pre-Inventory to delineate stands that may

have originally been incorporated into several other stands. It can save you the

trouble of numerous splits and merges.


Filling out the Pre-Inventory Attributes

After each delineation/edit that results in a new polygon, a data entry form

(pictured above) appears that allows definition of the attributes for the new

stand(s). When delineating stands, you must update the following attributes

before a stand is complete:

Forested Stands: Check the box to specify the stand as Forested.

Nonforested Stands: Check the box to specify the stand as Nonforested AND

specify your best estimate for a Pre-Inventory covertype call in the box labeled

Nonforested Code. Refer to Appendix A for the decision rules on Nonforested

stands.

You can also access the attribute editor by selecting a polygon and

clicking on the attribute editor button.

This editor button is one of the most powerful tools (and also one of the plainest

looking!) in the entire system. It allows you to edit the database behind the

shape on the screen. Remember, often times the data behind the stand or

treatment is more important than how it looks on the map! The attribute editor

is often the easiest way to access and edit that data.


A split, island, burn-in, or line-cutter buffer editing action will result in the

creation (and selection in highlighted blue) of at least two polygons (maybe

more). The new stand will inherit the Forested and Non-Forested identification

of the stand it originated from, while the acreage will be updated and a new

stand number will be automatically generated by the system. The exception is

the Is field work complete? field, which defaults to No in the new stand. This

attribute should remain No for now. You will edit this attribute during field data

collection (optional).

When you click on a stand number in left margin of the attribute editor, the

selected stand will flash on the map. Use this function to be sure that attribute

edits are being made on the correct stand.

After creating a new stand, verify that it meets minimum mapping sizes.

Select the Non-Forested or Forested attribute during this initial stand

delineation.


If the stand appears to be non-forested, (less than 25% of the ground is covered

by tree canopy), enter an estimated cover type code. This should be determined

from imagery and other supplementary information available at this time, such

as NWI (National Wetlands Inventory), USGS DRG (Digital Raster Graphics), old

OI records, FTP files, etc.

If you add comments, the Save icon will enable. Click anywhere on the form

to save the comment. (Note: This does not permanently save the comment until

the edit session is saved). Comments should be added anytime the delineation

is less than obvious comments will be used by central review team to review

delineations. You may also be able to view your comments when taking this

data into the field using Solo Forest field GIS software.

In some cases, creating a stand requires 2 edit actions. For example, with a road

polygon that traverses the compartment, each edge must be edited. In this

case, dismiss the attribute editor window after defining the first edge of the 2-

sided polygon without entering any attributes.

After creating a new stand, verify that it meets minimum mapping sizes.

Site Conditions

Site Conditions can be delineated the same way as Pre-Inventory stands and can

be started, if desired, during the Pre-Inventory digitizing process. The same tools

apply on Toolkit 7_Site Conditions: island, split, merge, explode and Burn In

Polygon as on the Pre-Inventory Toolkit. Digitizing can be done simultaneously

or by using Pre-Inventory stand lines as they are drawn using the Burn In

Polygon tool. Using this tool to its advantage will take practice. Delineation of

Site Conditions does not have to be completed during this stage, but some

advantages to getting started exist. See Chapter 16 for further information on

digitizing Site Conditions and Appendix O for a complete listing of Site

Conditions.


Central Review Process

In any stand delineation, the power of the pen is a valuable tool. In order to

ensure consistency in delineation to adhere to mapping rules and to balance

the lumpers and the splitters and to ensure quality and resource

consideration, a review process has been developed. There are three basic

stages:

Delineators quality control check

Review by other local interests

Central review

Delineators quality control check

When the examiners are satisfied that they have adequately delineated cover

types, they are to check through the compartment for several items:

Do all stands meet minimum mapping standard rules?

Have all stands been designated as either Forested or Non-Forested?

Do all Non-Forest stands have a best estimate Non-forest cover type

code entered?

There are several tools you can use to check that all stands meet minimum

mapping standards. Below are instructions on the two easiest to use.

The Symbol Picker:

This is the easiest tool to use for checking your work. To check that all stands

are designated as either forested or non-forested, use the Symbol Picker for the

Pre-Inventory layer (refer to Appendix Z for use of the Symbol Picker). In the

symbol pickers for the Pre-Inventory layer, there is a folder titled Central

Review. It contains five different renderings of the Pre-Inventory layer that will

allow you to check for most issues that arise during central review. This will

symbolize the Pre-inventory layer based on whether the stand is forested, non-

forested, or unspecified.


1. Start with the imagery turned off, and zoom to the extent of your

compartment.

2. Right click on the Pre-Inventory Stands layer in the Table of Contents, and

choose Symbol Picker from

the menu.

3. One at a time, choose one of the symbol rendering types in the Central

Review folder.

4. Stands will be displayed in a way that you can check that your delineation

meets the specifications for all Forested and Nonforested stands.

The Custom Query Tool

Another strategy for completing Pre-Inventory attribution is to use the Custom

Query tool. For example, to find non-forested stands missing a cover type code:

1. Open the Custom Query tool found in the QRM toolkit (See Appendix

Z).


2. Copy the Non-Forest with cover type query from System Queries to My

Queries. This allows changes to be made no edits can be made on

queries that are under the system queries tab.

3. The first step of this query sets your compartment otherwise you will

query the entire statewide database. The second step selects non-forest

stands from that compartment, and the third steps selects from those the

stands that do not have a cover type coded.

4. Use the build button on the first step to change the compartment

number to the appropriate compartment. Run Query. You can also zoom

to the resulting selection with the zoom to selection button.

5. To fix the selected stands, start an Edit session. Make sure that Selection

tab is set to Pre-inventory Stands.

6. Select the attributes icon in the editor toolbar to display the custom

attributes editor.

7. For each selected stand, estimate the Non-forest label where it has not

yet been done.

Other considerations prior to central review:

1. Use the comment field for entering information about special

considerations that the central reviewers may need to be aware of.

2. After entering comments, be sure to click the Save icon before moving to

the next stand. To close the attribute editor, click on the X in the upper

right corner.

When all of the above steps are complete, the delineator notifies the local wildlife

staff (or forestry staff if delineator is wildlife staff) and the District Inventory and

Planning Specialist that the compartment is ready for local review.

Review by other local interests

Forestry and Wildlife staff should work together throughout the stand delineation

process. The examiner should discuss concerns and considerations with their


alternate in the other division at the Inventory Preview meeting. Co-managers

concerns should receive full consideration during the entire inventory process.

After the initial stand delineation is done, the local wildlife staff can review the

compartment (or vice-versa if wildlife staff are the examiners). Unit managers

may also want the delineation checked by another forester at times in interest of

local quality control.

The local review should include:

Have all stands been delineated correctly?

Have all stands been classified as either forested or non-forested?

Are the non-forested cover calls reasonable?

After the local review is complete, the examiner notifies the District Inventory

and Planning Specialist that the compartment is ready for central review.

Central Review

The central review will occur at either the district or state level and include both

forestry and wildlife reviewers. This is a quality control check to see that

mapping standard rules are met and to look for major problems.

Have all mapping rules been met?

Are stands being consistently identified?

Are there problems with the delineation that need to be corrected

before field work begins?

After the central review is complete, the District Inventory and Planning

Specialist proceeds to geographic renumbering.

Geographic Renumbering

At initial delineation stand numbers are automatically created for every new

stand based on the order they were created without any regard for geographic

proximity.


When a compartment passes central review, the central reviewers will use the

geographic renumbering tool. Using this tool, the stands are renumbered

geographically starting from the upper left (most Northwest stand) and ending in

the lower right (Southeast) corner.

Once the stands have been renumbered, the District Inventory and Planning

Specialist notifies the examiner and the compartment is ready to move to the

next phase preparation for stage 1 field data collection.
