Who We Area & What We Do
http://www.biology.ualberta.ca/facilities/gis
Each year 40-80 researchers integrate:
• GIS
• remote sensing
• satellite telemetry
to improve or develop alternative methods used in their
ecosystem and wildlife investigations
3
ACCRU
Associated with the Alberta Cooperative
Conservation Research Unit (ACCRU) –
a multi-disciplinary and multi-institutional research and
learning centre
http://www.biology.ualberta.ca/accru
4
Terrestrial & Aquatic Research
Simply visualize spatial patterns of collected field data
Complex modelling in conservation biology
and landscape ecology methodologies
Quantity of data that must be quantified
necessitates automated batch solutions
5
Challenges in Ecology
ResearchBasic out-of-the-box functionality of the GIS
software often needs to be taken one step
further to:
• fully address the specialized applications
• increase productivity
Although other custom applications (MGET, GME, and
HRT) are excellent free third-party extensions… they do
not allow modification

Solutions: Open Flexible
ApplicationsModelBuilder and Python:
• are free
• tools are easily reconfigurable with different
parameters/arguments/variables
10
ACCRU Tools
http://www.biology.ualberta.ca/facilities/gis
11
Licensing Requirements
Majority accessible with ArcView
Several require Spatial Analyst
Tools requiring ArcInfo:
• Measures Per Area (polygon input)
• Percent Contours From ASCII (polygon output)
• Date Matched Contours (near tool)

ArcGIS
9.3+
The Toolbox
Easily
accessible
Model and
Script tools
Grouped by
categories of
common use – but
may be applied to
alternate use
13
Structure
The label of each tool is
prefixed by a categorical
numbering system
Allows for efficient
indexing and searching
in ArcToolbox
The numbering is not meant to
be followed in a linear fashion
14
How To Use
Command Line and Python
scripting references the basic
tool name (i.e. does not have
the numbering prefix)
Recommend accessing
tools via ArcCatalog
Documentation via tool
dialog side-panel help
15
Workflows
To use ACCRU tools fit the custom tools
together (along with any built-in tools) for complete
conservation ecology workflows
Which bird nesting locations would be affected by the density of new
roads to simulated forest cut blocks?
