Read a GeoPackage

Sample Viewer View Sample on GitHub

Add rasters and feature tables from a GeoPackage to a map.

Use case

The OGC GeoPackage specification defines an open standard for sharing raster and vector data. You may want to use GeoPackage files to support file-based sharing of geographic data.

How to use the sample

When the sample loads, the feature tables and rasters from the GeoPackage will be shown on the map.

How it works

  1. Create a GeoPackage object using the path the local geoPackage.
  2. Connect to the GeoPackage.loadStatusChanged signal.
  3. Load the geoPackage geoPackage.load(), then iterate through the available rasters, exposed by geopackage.geoPackageRasters.
    • For each raster, create a raster layer then add it to the map.
  4. Iterate through available feature tables, exposed by geopackage.geoPackageFeatureTables.
    • For each feature table, create a feature layer then add it to the map.

About the data

This sample features a GeoPackage with datasets that cover Aurora, Colorado: Public art (points), Bike trails (lines), Subdivisions (polygons), Airport noise (raster), and liquour license density (raster).

Additional information

GeoPackage uses a single SQLite file (.gpkg) that conforms to the OGC GeoPackage Standard. You can create a GeoPackage file (.gpkg) from your own data using the create a SQLite Database tool in ArcGIS Pro.
