GeoPackage - Introduction¶
The GeoPackage Encoding Standard describes a set of rules and conventions for storing vector features, imagery tile matrix sets, raster map tile matrix sets and non-spatial tabular data in an SQLite database. The standard also describes rules for extending the capabilities of a GeoPackage.
GeoPackage 1.0 was approved as a standard in January 2014. GeoPackage 1.1 was approved as a standard in August 2015. GeoPackage 1.2 was approved as a standard in August 2017. GeoPackage 1.3 was approved as a standard in November 2020.
1.3 is the current latest version
- Test Suite
A test suite exists in the OGC repository.
GeoPackage is used for storing and accessing:
Vector feature data
Imagery tile matrix sets
Raster map tile matrix sets
Non-spatial tabular data
Metadata that describes other stored data
Implemented in an SQLite database
Feature geometry is encoded in Well Known Text (WKT) based on the OGC OpenGIS® Simple Features Interface Standard (SFS)
Supports both vector feature data and tile matrix sets of imagery and maps
Ideal format for encoding geospatial data where Size, Weight and Power (SWaP) are limited
Relation to other OGC Standards¶
Due to its XML serialization, GML is well suited to geospatial data exchange across networks. In contrast, GeoPackage is better suited to storage and random access of geospatial data on a file system. GeoPackage implements the OGC OpenGIS® Simple Features Interface Standard (SFS) which provides a common way for applications to store and access feature data in relational or object-relational databases.
