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

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 ToolsTools that prepare, manipulate, and analyze data spatially

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

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

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

Resource Data• Contain information and data about the
resources of interest
• Can be feature classes
![Page 9: Habitat Analysis in ArcGIS](https://reader033.vdocuments.net/reader033/viewer/2022061511/5681494f550346895db69d8c/html5/thumbnails/9.jpg)
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

Rasters Containing Thematic Data
• Represent some measured quantity or classification of a particular phenomena
![Page 11: Habitat Analysis in ArcGIS](https://reader033.vdocuments.net/reader033/viewer/2022061511/5681494f550346895db69d8c/html5/thumbnails/11.jpg)
Image Rasters
• Images or photographs
• Still composed of cells
• Cells represent colors or spectral reflectance

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
![Page 25: Habitat Analysis in ArcGIS](https://reader033.vdocuments.net/reader033/viewer/2022061511/5681494f550346895db69d8c/html5/thumbnails/25.jpg)
Joining TablesGetting output data into master datasets
Common Attribute(Unique Identifier)
Master Dataset Output from Tool

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

• Right click on a Toolbox• Go to “New” “Model”
![Page 31: Habitat Analysis in ArcGIS](https://reader033.vdocuments.net/reader033/viewer/2022061511/5681494f550346895db69d8c/html5/thumbnails/31.jpg)
• 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
![Page 32: Habitat Analysis in ArcGIS](https://reader033.vdocuments.net/reader033/viewer/2022061511/5681494f550346895db69d8c/html5/thumbnails/32.jpg)
After saving the model, open the model from ArcToolbox to see a dialogue box where you can specify the input and output parameters
