High‑Performance, Dependency‑Free Terrain Visualization
The RRIM Toolbox is now available as a fully ArcGIS Pro–native Python toolbox designed for high‑resolution terrain visualization in geomorphology, archaeology, hydrology, and landscape analysis.
This release provides:
- Native Topographic Openness (POS/NEG)
- Openness Index (POS–NEG)
- Slope from DEM
- Red Relief Image Map (Custom)
- Red Relief Image Map (Classic)
All tools run inside ArcGIS Pro’s default Python environment using only NumPy and GDAL already bundled with Pro — no external installs, no conda, no RVT dependency.

🛰️ About RRIM
Red Relief Image Maps combine openness, slope, and color‑mapped blending to produce high‑contrast terrain visualizations ideal for scientific analysis and publication‑quality figures.
This toolbox implements both modern Cividis‑based RRIM and classic red‑on‑gray RRIM with optimized, tiled GeoTIFF output.
🧭 System Requirements
- ArcGIS Pro 3.x
- Python 3.9 (default)
- NumPy + GDAL (included)
