FAQ: GeoPackage for Lac

Why is GeoPackage better than Shapefile?

GeoPackage stores all layers in one file, supports long field names, UTF-8, and has no size limit.

Can I open GeoPackage in QGIS?

Yes, QGIS is the best free editor for GeoPackage. Just drag the file into the window.

How do I find out which layers are inside the file?

In QGIS they are shown as a list when you add the file. On the command line — ogrinfo -so map.gpkg; in Python — fiona.listlayers("map.gpkg").

Which coordinate system do the layers arrive in?

WGS84 (EPSG:4326). You can reproject right inside QGIS when saving a layer, or with the ogr2ogr command and the -t_srs switch.

Can I edit the file and add my own layers?

Yes. A GeoPackage is a full-fledged SQLite database: QGIS writes edits and new layers into it, and any SQLite client runs SQL queries against the tables.
