Overview
QGIS-RRIM is a QGIS plugin that implements the Red Relief Image Map (RRIM) technique for enhanced terrain visualization using digital elevation models.
Methodology
The plugin generates the fundamental raster layers required for RRIM visualization:
- Slope
- Differential openness
These layers are combined to enhance micro-topography, scarps, lineaments, and subtle geomorphic features while remaining largely independent of illumination direction.
Applications
- Geomorphological mapping
- Morphostructural analysis
- Tectonic interpretation
- High-resolution topographic analysis
Implementation
The plugin is fully integrated into the QGIS Processing Toolbox and supports multiple DEM sources, including LiDAR-derived datasets.
Release
GitHub release available through the official repository.
