.GPKG

📌 A .GPKG specification is closely focused on the compound GeoPackage database file basement. Precisely, the .GPKG arrangement includes specific data tables that recognize geospatial data, which may be properly saved in both vector and raster extension layouts. For instance, a typical .GPKG data element may include a bundle of vector overlays managing the internal features on the distinctive map areas, a comprehensive set of raster maps of the aforementioned area depicted at various scales, and various metadata items. The .GPKG, or in other words GeoPackage, format pattern has been invented and designed by the Open Geospatial Consortium (OGC) in 2014. The .GPKG technology was primarily oriented on designing both vector and raster data at the same time remaining entirely and productively decodable, for further usage with lightweight web and mobile software projects and initiatives. Each of the particular .GPKG file hierarchies refers to an SQLite 3 database which involves a range of multiple data tables. The tiles of the aforementioned .GPKG embraced tables are comprised of the raster maps saved in the pyramids, applied to zooming in appropriate geographic areas at higher map scaling and resolutions. These relevant maps are commonly handled, operated, and opened up as .JPEG or .PNG graphical instances. Miscellaneously, featured tables maintain vector data resources overlaid on the predefined maps, to efficiently demarcate certain geographic options and abilities. Other categories of tables involved into .GPKG specification logic are composed of extensions tables, attributes, and associated file metadata.

How to open an .GPKG file?

📌 The .GPKG file resources can be freely and effortlessly revealed, opened, and examined by QGIS, GeoServer, GDAL, or ESRI ArcGIS for Desktop program solutions, adaptable for all types of operating platforms and architectures. Finally, if you don’t desire to preinstall any auxiliary .GPKG compatible software or utilities on your desktop PC, make use of NGA GeoPackage Viewer web-service, runnable from any web-browser accessible in your working area or infrastructure.
