The GeoBase file system A methodology of storing spatial data for optimal performance in geospatial or location-based applications.
For more information see the GeoBase File Systems FAQ page. (or GBFS) is a methodology of storing spatial data for optimal performance in geospatial or location-based applications.
GBFS takes 3rd party spatial data sets - such as street data, building outlines, POI's- and compresses the information through a bit-encoding process. This process is lossless- meaning the resulting data set retains all of the information in the source data. For the US & Canada, the source SHP files are ~20 GB in size; the compile process yields a 1.8GB GBFS A methodology of storing spatial data for optimal performance in geospatial or location-based applications.

GBFS also includes spatial indexes so that the data sets can be quikly searched by mapping engines, geocoders and general spatial queries.
