Geography 465 Working with ArcGIS Tools and Environment Settings

Toolbox defined

Standard Toolboxes

Parameters are specified using strings or objects

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

Environment Setting

Save Environment Setting

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

Complex Parameters - Objects

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

Describe method - 9.3
