lecture: Using and extending GeoPackages
GeoPackage is an OGC standard combining vector data and raster tiles in a single database file. Since its official publication in February 2014 adoption has grown very quickly and the new format got support by most major Open Source and proprietary software products.
Its combination of easy distribution and efficient use thanks to an SQL interface makes it interesting in a wide range of usage scenarios from embedded devices up to Open Data portals.
This presentations shows the current state of support in Open Source applications like GDAL and QGIS, but also covers recent and planned extensions of the format. Examples are the proposed GeoPackage Elevation Extension, an extension for storing point cloud data and the recent QGIS all-in-one GeoPackage format. The latter implements storing map styling information right in the GeoPackage file, allowing to distribute a dataset together with map views and print layouts in one file.
