This site, created by Tom Patterson, started out as a resource for cartographers creating shaded relief, panoramas, land cover, and related raster art on maps. It has since grown to include his other cartographic interests and has become a repository for his maps, all of which are in the public domain. It also includes articles and tutorials on the topic of cartography.

An open-source tool for reading OpenStreetMap PBF files using DuckDB.

• Scalable reader for OpenStreetMap ProtoBuffer (pbf) files.
• Is based on top of DuckDB1 with its Spatial2 extension.
• Saves files in the GeoParquet3 file format for easier integration with modern cloud stacks.
• Utilizes multithreading unlike GDAL that works in a single thread only.
• Can filter data based on geometry without the need for ogr2ogr clipping before operation.
• Can filter data based on OSM tags.
• Utilizes caching to reduce repeatable computations.
• Can be used as Python module as well as a beautiful CLI based on Typer4.

A Cloud Optimized GeoTIFF (COG) is a regular GeoTIFF file, aimed at being hosted on a HTTP file server, with an internal organization that enables more efficient workflows on the cloud. It does this by leveraging the ability of clients issuing ​HTTP GET range requests to ask for just the parts of a file they need.
