Zonation in practice: tutorial and GUI

2

Simplified Zonation workflow

1 Data collation and manual preprocessing (GIS)

2 Automated preprocessing using Zonation

3 Iterative landscape ranking (Zonation run)

4 Visualization, automated output & post-processing

5 Manual/external post-processing in GIS

3

Species distributionsBiodiversity distribution data1

Spatial (static) patterns of biodiversity

4

Manual pre-processing of data2

5

• In the GUI, setups are included in “projects”• A minimum setup requires

• Define a project (potentially several variants/runs)• Features/species list• A set of raster maps: one for each feature in the list• Settings definition (if empty, defaults are used)

3 INPUT: Zonation setup

6

• Biodiversity feature raster• Example: .tif, .img or .asc file; standard GIS formats

as supported by GDAL (http://www.gdal.org/)• Raster showing the species occurrences and the

dimensions of the raster

• Basic setup: one raster for each feature

3 INPUT: a set of raster maps

7

3 INPUT: a set of raster grids

Example: ascii raster files(as in the tutorial)

• Biodiversity feature (e.g. species) list file• text file, frequently with extension .spp for distinction • List of all those biodiversity feature raster map files

included in the analysis

• Trick: same map can entered multiple times for connectivity, retention etc. analyses

• More details about files, later

INPUT: features/species list file (.spp)4

18

• Open Zonation GUI (zig3gui.exe) • Open project: do_zig3.bat

• It uses:• Features list file: splist.spp• Settings file: set.dat

Basic core-area Zonation

19

Feature raster mapsSpecies weightsOther parameters (onlyneeded for more complex analyses)

Setup files: features/species list

20

Setup files: settings (.dat)

If empty,defaults are used

21

Project: all the pieces together

Setup files: Project file (.bat)

22

• The .spp, .dat and .bat files are actually text files that can be edited with any text editor, including notapad. The .spp and .dat extensions have been used for distinction. The .bat is the extension of a dos/windows batch command file.

Note about .spp, .dat and .bat files:

23 Explore settings and input files in the project tree

Right-click on files to edit

Expand settings and files included in an instance/setup

24

• Prefix of names: fourth parameter to zig3.exe• Priority ranking map (raster and image: .jpg)• .curves.txt performance (representation) of each

feature during the cell removal • .run.info.txt keeps track of analyses, files and

settings (details how the software runs)

• .rank.asc, .prop.asc, .wrscr.asc, and others for post-processing in GIS

Output files

25

• Open project do_w.bat• Open features list file splist.spp (right-click -> Edit)

Example: change species weights

Change weights, save and re-run

26

• Open project do_ds.bat (then right-click -> Edit)

Example: distribution smoothing

Distribution smoothing: ON Factor to multiply feature-specific (dispersal) parameters

27

Multiple runs in a same project

• Open project do_multiple.bat

You can use the tutorial files as templates for your own projects

• Fire up the GUI and open project do_abf.bat• Explore the project tree:

• Display some of the input raster files• open the .spp and .dat files. What’s there?

• Run (queue) the project• Explore the results (in GUI and output files)• Compare top areas with ABF (do_abf) against

CAZ (do_zig3). Tip: use ”merged maps”• Plot results using ”interactive plots”
