Using Python within ArcGIS requires foundational Python knowledge. The following modules support Python integration:

(1) Python Window

Implementation Steps:

  1. Import ArcPy:

    import arcpy

  2. Execute commands directly:

    arcpy.env.workspace = "C:/Data/Tongass"
arcpy.Clip_analysis("standb4", "clipcov", "standby_clip", "1.25")

Key Features:

  • Default Workspace: arcpy.env.workspace defines processing locations, enabling layer access by name without full paths
  • Tool Drag-and-Drop: Drag tools into the window to auto-generate corresponding code
  • Path Retrieval: Copy layer paths directly from Catalog
  • Built-in Help: Right-click tools for parameter documentation (Chinese language pack recommended)
  • Code Completion: Real-time tooltips display parameters and descriptions

(2) Field Calculator

Execute Python scripts for field operations (e.g., renaming fields, calculating geodesic areas):

(3) Model Builder

Embed Python scripts to extend functionality:

  1. Incorporate custom Python tools

  2. Call scripts within Calculate Field

    import arcpy 

input = arcpy.GetParameterAsText(0) 
clip_features = arcpy.GetParameterAsText(1) 
output = arcpy.GetParameterAsText(2) 
arcpy.Clip_analysis(input, clip_features, output)

Note: Custom script tool creation will be detailed in future updates.
