How to Create Geopackage in QGIS

Learn the difference between creating and adding layers to a GeoPackage in QGIS. Understand how a GeoPackage works, why geometry types must be specified, and how it stores multiple layers in a single file.

A GeoPackage is a single file that can store all kinds of map data—like points, lines, polygons, tables, and even images—in one place.

In simple terms:
Think of a GeoPackage (.gpkg) like a digital container or map folder that holds:
• Your map layers (e.g., roads, rivers, buildings),
• Their attributes (e.g., names, heights, types),
• And even raster images or basemaps.
But unlike folders with many files (like shapefiles), a GeoPackage keeps everything neat and compact in one file.

Why it matters:
• It’s portable — easy to share and move around.
• It’s efficient — stores large data without clutter.
• It’s modern and flexible — works in QGIS, ArcGIS, and more.
• It can hold many layers of different types in one file.

Example:
Instead of sending:
• roads.shp
• rivers.shp
• buildings.shp
• buildings.dbf
• roads.prj

You send just one file: project_data.gpkg
