The main map generator is mostly local and coherent, but the package includes under-disclosed network, caching, and credential-handling helpers that do not fit the advertised offline map-export purpose.
Review this package before installing in an environment with real credentials or sensitive project locations. The main CLI appears intended for local map generation, but the bundled helper modules should be removed, narrowed, or clearly documented before use, especially the hardcoded Earthdata credentials, netrc/secrets access, external geocoding, home-directory cache, and unpinned dependencies.
