About
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
