An open format for geographic information system data based on SQLite.

GeoPackage is a compact, portable, self-describing and platform-independent data format for geographic information systems (GIS). It is based on SQLite, an open-source database software, that offers an efficient way of storing, managing, and distributing geospatial data.

As a file-based data container, GeoPackage conveys and manipulates vector geospatial features, tile matrix sets of imagery and raster maps at various scales, as well as attributes directly to, from, and within mobile devices, web clients and desktop applications. Importantly, it allows for both the transfer and use of spatial data in a consistent manner across these platforms.

GeoPackage was adopted as an Open Geospatial Consortium (OGC) standard to facilitate better interoperability and use of geospatial data. Users are no longer tied to a particular software or GIS applications, as GeoPackage enables seamless data sharing and exchange between users, regardless of the application used.

The GeoPackage format encompasses a complete set of features necessary for effective geospatial data management. These include but are not limited to: straightforward storage of vector features, the inclusion of elevation data, the possibility of layer attributing, flexible data indexing, and advanced spatial querying for geographic operations and analysis tasks.

Storing data in the GeoPackage format comes with notable advantages. Firstly, the SQLite basis of GeoPackage ensures a high level of data access efficiency and speed. The use of SQLite allows for direct data read and write, without any slow server requests or conversions involved. Moreover, SQLite's query capability promotes interactive and dynamic map displays.

GeoPackage's standard also allows for appending data, making it possible for users to add more data to an existing GeoPackage file. Data can be instance-wise, spatially distributed points, or comprehensive geographical features, providing immense flexibility.

Secondly, due to its file-based nature, GeoPackage data can be stored locally on a device, removing the need for constant internet connectivity. Geospatial data in the GeoPackage format is also inherently portable and can easily be shared or transferred via email, cloud storage, or other file transfer method.

In summary, leveraging the GeoPackage format in GIS applications brings forth a lightweight, OCI standardized, self-contained, and interoperable system for geospatial data exchange, storage, and manipulation. It streamlines the user's interaction with geospatial data by ensuring accessibility, portability, and usability across multiple platforms. GeoPackage, through its integration with SQLite, has revolutionized the interface between users and spatial data.
