Publishing GeoPackage to GeoServer Using QGIS

Recently, I had the occasion to attempt to generate an OGC GeoPackage from QGIS and publish it using GeoServer. The use case was fairly straightforward. I had been given data in GML format and needed to publish it. For many valid reasons (such as lack of spatial indexing), GeoServer does not natively support publishing GML data. As a result, I need to convert it to something that GeoServer did support.

QGIS opened and displayed the data easily and, from there, I could export it into any number of formats. (Or I could have used OGR.) The feature attributes had very long names and I didn’t want to lose that richness by exporting to shapefile. I was trying to keep my server-side life simple, so I was hoping to avoid setting up an RDBMS data store for this purpose. It was then that I noticed QGIS supports exporting to GeoPackge, so I decided to give it a go.

For purposes of this post, I am using a shapefile of building footprints of Leonardtown, Maryland. The process is the same for a GML file, however.

As shown below, you initiate the process like any other by right-clicking and choosing “Save As…” in the context menu.

Comment Period Open for GeoPackage Specification Draft

The Open Geospatial Consortium (OGC) has published a draft GeoPackage specification for comment. The GeoPackage specification attempts to create a non-proprietary means for packaging and exchanging all geospatial data in all its forms (vector, raster, and tiles). A couple of things that jump out at me:

  • It calls out SQLite as the reference implementation of a GeoPackage container
  • It calls out SpatiaLite 4 as the reference implementation of a vector feature store
  • It does not call out a reference implementation for rasters or tiles
  • It does not mention exchange of cartography.
