PyGILE-Plus v1.1.0

PyGILE-Plus v1.1.0

Major Additions

• Introduced a complete notebook-based geospatial analysis workflow
• Added STAC + Microsoft Planetary Computer integration for DEM discovery and download
• Implemented end-to-end watershed-based terrain analysis pipeline

New Analysis Workflow

1. DEM acquisition via STAC / Planetary Computer
2. Automated watershed delineation with pour point
3. Terrain derivative computation (slope, aspect, curvature, TPI, TWI, TRI)
4. Edge detection and texture analysis
5. Final landform classification

New Notebooks

  Centralized JSON-based configuration for paths, tools, parameters, and visualization
• 02_Python_Geospatial_Ecosystem
  Overview and categorization of 80+ geospatial Python packages used in PyGILE-Plus
• 03_Watershed_Delineation
  Automated watershed extraction from DEM using WhiteboxTools
• 04_SAGA_GIS_Tutorial
  Terrain analysis including slope, curvature, TWI, TRI, and convergence index
• 05_GRASS_GIS_Tutorial
  Advanced terrain metrics including TPI, roughness, and neighborhood analysis
• 06_OTB_Tutorial
  Edge detection, texture analysis, and filtering applied to DEMs
• 07_WhiteboxTools_Tutorial
  Hydrological modeling and geomorphometric landform classification

GIS Engine Integration

• WhiteboxTools for hydrological and geomorphometric analysis
• SAGA GIS for terrain derivatives
