GeoPackage Viewer for macOS

• Open a .gpkg and see what is inside, layer by layer
• MapKit integration to put the spatial data on an actual map
• export to WKT when you need the geometry as text.

GeoPackage is the OGC standard that replaced the shapefile: one .gpkg file holding vector features, attributes, tile layers and metadata, built on SQLite. It is what modern GIS exports look like, and on a Mac without QGIS installed it is a blank icon.

GeoPackage Viewer reads them as GIS data rather than as a generic database. The layer sidebar comes from the gpkg_contents catalogue and shows feature layers and tile layers with their coordinate reference systems and bounds. Attribute tables browse, sort and filter like any table. Geometry columns display as POINT, LINESTRING or POLYGON with their vertex counts rather than as unreadable binary, and the geometry inspector lets you double-click any geometry to see its shape, its coordinates, and copy it as WKT.

Reading the geometry meant implementing the GeoPackage binary header and the underlying well-known binary format directly, including the coordinate reference system identifiers that determine how a geometry should be interpreted.

GeoPackage Pro adds the map view: feature layers plotted on Apple's basemap for the common web and GPS projections, with per-layer toggles and a legend, plus an offline true-to-shape coordinate plot for any other projection, a layers diagram, and export to CSV with geometry as WKT or to SQL.

Built on the same fast engine as Fast SQLite Viewer — a GeoPackage is SQLite underneath, after all.
