1. Habitat Analysis in ArcGIS Use of Spatial Analysis to characterize used resources Thomas Bonnot http://web.missouri.edu/~bonnott/

2. Introduction GIS Modeling –Summarizing characteristics of resources associated with fish and wildlife use Resource Selection, Survival, Movement Descriptive and Exploratory Purposes –Types of GIS Data Involved Organization and Preparation of Data Ways to automate Geoprocessing

3. Spatial Analysis Spatial Analysis: The study of the locations and shapes of geographic features and the relationships between them Measuring distances between points Modeling the behavior of ecosystems Geoprocessing Tools Tools that prepare, manipulate, and analyze data spatially

4. Characterizing resources associated with features of use Inputs –Features representing use –Resource or environmental data of interest

5. Spatial Features Types of features in ArcGIS 1)Point  Nest Site; Telemetry Location 2)Line  Movement Path; River ; Xsct 3)Polygon  Home Range; Nest Plot

6. Spatial Features cont. Feature Class –Group of features of the same geometry –Can be filed in different formats Shapefile

8. Resource Data Contain information and data about the resources of interest Can be feature classes

9. Rasters Made up of square cells Each cell represents a specific portion of an area –Describes location and relative position in space –And the characteristics of that area

10. Rasters Containing Thematic Data Represent some measured quantity or classification of a particular phenomena

11. Image Rasters Images or photographs Still composed of cells Cells represent colors or spectral reflectance

12. Missouri Land Cover, Classified Satellite Imagery – 30m

13. USDA NAIP Color Infrared Aerial Photography – 1m

14. Digitized Land Cover for Study Site

15. Have the Data. How do we characterize? Use Features Resource Data Layers

16. Geoprocessing for Characterizing Used Resources Use Feature Resource DataGeoprocessing Tool Points Feature ClassSpatial Join Polygons Points RasterZonal Statistics as Table Polygons Clip then Calculate Areas (When summarizing areas of polygons in polygons)

17. Geoprocessing for Characterizing Used Resources Use Feature Resource DataGeoprocessing Tool Points Feature ClassSpatial Join Polygons Points RasterZonal Statistics as Table Polygons Clip then Calculate Areas (When summarizing areas of polygons in polygons)

18. Right Click on the Layer and go to “Joins and Relates”

19. Geoprocessing for Characterizing Used Resources Use Feature Resource DataGeoprocessing Tool Points Feature ClassSpatial Join Polygons Points RasterZonal Statistics as Table Polygons Clip then Calculate Areas (When summarizing areas of polygons in polygons)

21. Geoprocessing for Characterizing Used Resources Use Feature Resource DataGeoprocessing Tool Points Feature ClassSpatial Join Polygons Points RasterZonal Statistics as Table Polygons Clip then Calculate Areas (When summarizing areas of polygons in polygons)

24. Organizing Data Tables in ArcGIS Important Consideration in Spatial Analysis Geoprocessing Tools produce outputs in different tables and with different formats Joining and Summarizing Tables

25. Joining Tables Getting output data into master datasets Common Attribute (Unique Identifier) Master Dataset Output from Tool Desired Attribute

26. Right Click on the Layer Go to “Joins”  “Relates”

27. Summarizing Tables Multiple Records For the Same Feature When output tables have

28. Right Click on the Field Go to “Summarize” Choose statistic to summarize

29. Model Builder to automate Geoprocessing Create Models to link together multiple Geoprocessing Tools Can set parameters ahead of time or allow for them to be entered manually

30. Right click on a Toolbox Go to “New”  “Model”

31. Click and Drag tools to Model Builder Window Connect tools together so that outputs from one tool become inputs for the next To Create Parameters Right click on Tool Go to “Make Variable”  “From Parameter” Select the parameter for use in the dialogue box

32. After saving the model, open the model from ArcToolbox to see a dialogue box where you can specify the input and output parameters
