About FlatGeobuf
FlatGeobuf is a modern, high-performance binary format for geospatial vector data, designed for efficient streaming and cloud-native workflows. Based on FlatBuffers, it supports random access via HTTP range requests, making it ideal for serving large datasets directly from object storage like S3 without a tile server. FlatGeobuf is an OGC Community Standard and is supported by GDAL 3.1+, QGIS, Mapbox, and the GeoJSON ecosystem. Its compact binary encoding is significantly faster to parse than GeoJSON for large datasets.
Strengths
- +Extremely fast read/write — binary encoding
- +Supports HTTP range requests for cloud-native access
- +OGC Community Standard
- +Compact — much smaller than equivalent GeoJSON
About KML
Keyhole Markup Language (KML) is an XML-based format developed for Google Earth and now maintained by the OGC. It is widely used in Google Maps, Google Earth, and many consumer-facing mapping applications. KML supports styled geometry, network links, folders, and time-based animations. It always uses geographic coordinates (WGS 84) and is stored as plain XML text. KMZ is simply a ZIP-compressed KML file, which can also include embedded images and other resources.
Strengths
- +Native in Google Earth and Google Maps
- +Supports rich styling and labels
- +Human-readable XML
