I’ve created an app that makes it easy to create great looking hill-shaded color relief images with GDAL. This simple tool offers an easy-to-use interface for editing colors and GDAL settings, provides quick previews of settings, and automatically runs all the GDAL commands necessary to generate a high-quality merged hillshade and color relief. There are lots of different ways to create color relief but I think this single purpose tool may offer some advantages:
Color Editor
- Instant Previews: Adjust color settings and see results immediately.
- Color Palette Selector: Easily assign colors to elevation ranges.
- Undo Support: Roll back changes.
- Insert/Delete Rows: Add interpolated rows, delete rows.
- Rescale Elevation Values: Rescale all values with a single click.
- Import: Import standard GDAL color files.
Hillshade Editor
- Real-Time Previews: Fine-tune hillshade settings and immediately view results.
Relief Image Generation
- Blending: Combines hillshade and color relief using composite multiply for high quality results.
- Optimized Workflow:
- Only rebuilds components when changes are made, saving time.
- Leverages multi-core processing for faster performance.
- All settings are automatically stored in a single config file.
- Post-Processing Tools: Launch external viewers like QGIS.
- Seamless Workflow: Copy the final image directly into your map project folder.
Elevation File Management
- Drag-and-Drop Elevation Downloads: Add elevation files with simple drag and drop.
- CRS Support: Sets Coordinate Reference Systems (CRS) for files.
- Source Management: Save URLs and license information for your elevation data.
