Package Exports
- geobuf
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (geobuf) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
geobuf
A compact encoding for geographic data.
Like vector-tile-spec, this is a protobuf-based encoding.
Unlike vector-tile-spec, this deals with untiled data in native projections.
