Understanding ArcGIS Toolbox and Environment Settings for Advanced Geoprocessing

This guide explores the workings of ArcGIS Toolboxes and Environment Settings. Users will learn how to define and manage standard toolboxes, set parameters using strings or objects, and understand the five categories of environment settings: General, Coverage, Geodatabase, Raster Geodatabase, and Raster Analysis. The documentation includes specifications for complex parameters and objects, such as spatial references and value tables. Detailed examples illustrate how to retrieve properties using Describe in Python, enhancing geoprocessing capabilities.

  1. Geography 465 Working with ArcGIS Tools and Environment Settings

  2. Toolbox defined

  3. Standard Toolboxes

  4. Parameters are specified using strings or objects

  5. Environment Settings Divided into five categories: • General • Coverage • Geodatabase • Raster geodatabase • Raster analysis Names are unique; same constraints as tool names

  6. Environment Setting

  8. Save Environment Setting

  9. Save Environment Setting

  10. Complex Parameters - Objects For example: Spatial references, value tables, weighted overlay tables, and remap tables Read/write properties Each tool documentation has the specification

  11. Complex Parameters - Objects

  12. Retrieving properties usingDescribe # Workspace dscWS = gp.Describe (“Seattle.mdb”) # FeatureClass Properties dscFC = gp.Describe (“Seattle.mdb\\Parcels”) # DataSet Properties dscFD = gp.Describe (“Seattle.mdb\\Census)

  13. Describe method - 9.3
