Professional-grade terrain analysis toolkit for QGIS featuring:
• Hydrological Analysis: D8 flow direction, flow accumulation, watershed delineation, depression filling, flow indices (TWI, SPI), flow distance/length, basin analysis
• Geomorphometric Analysis: Slope, aspect, curvature, hillshade, roughness, TPI, openness, visibility analysis, hypsometric analysis
• Stream Network: Stream extraction, Strahler/Shreve ordering, stream links, vectorization, gap joining, valley extraction
• Structured Workflow: Organized tools following standard hydrology analysis workflow
Key Features:
- Numba JIT acceleration for 10-100x faster processing
- Standard D8 flow direction encoding (industry-compatible)
- Automatic symbology for flow direction and stream order
- NoData handling with -9999 standard
How to Use:
1. Open Processing Toolbox (Ctrl+Alt+T)
2. Expand "MAS Spatial Analysis Tool"
3. Select algorithm category (Hydrological, Geomorphometric, Stream Network)
4. Double-click tool to run
5. Typical workflow: Fill DEM → Flow Direction → Flow Accumulation → Extract Streams
