Prep

• You'll probably want tag transformations : https://www.openandromaps.org/en/map-basics-2/tagtransform

Processing

1. Download various elevation data needed using phyghtmap (http://katze.tfiu.de/projects/phyghtmap/phyghtmap.1.html)
2. Download maps using download_maps.py
3. Create a custom map list (see custom.list for an example) for use
4. Run map processing with --no-map-download, --tag-mapping and --tag-transform
