GeoPackage is the modern alternative to formats like SDTS and Shapefile. Its SQLite-based format efficiently stores and transfers geographic vector features and image tiles.
GeoPackage is the modern alternative to formats like SDTS and Shapefile. At it’s core, GeoPackage is simply a SQLite database schema. If you know SQLite, you are close to knowing GeoPackage. Install Spatialite – the premiere spatial extention to SQLite – and you get all the performance of a spatial database along with the convenience of a file-based data set that can be emailed, shared on a USB drive or burned to a DVD.
GeoPackage was carefully designed this way to facilitate widespread adoption and use of a single simple file format by both commercial and open-source software applications — on enterprise production platforms as well as mobile hand-held devices. GeoPackage is a standard from the Open Geospatial Consortium. It was designed and prototyped following a multi-year, open process of requirements testing and public input. It is designed for extension. So if you need more than the core GeoPackage feature set, join OGC's open process to standardize community-tested enhancements.
