Home · Features · GeoPackage Studio

The GeoPackage is the database. This is its studio.

Design schemas, import five vector formats, edit features with real Z elevations through native ArcGIS Editor widgets, read ESRI mobile geodatabases — all offline.

Manage

Design it, fill it, ship it

Schema editor, import .gpkg / GeoJSON / Shapefile / FlatGeobuf / Parquet, export GeoJSON or CSV — all offline on disk.

Z + M preserved

ESRI JSON ↔ NTS ↔ OGC GPKG blobs — verified bit-exact round trip at z = 1500.5.

Native Editor widget

Z-aware FeatureLayer with absolute-height elevation — stock ArcGIS Editor in SceneView.

Transactional edits

applyEdits batch with rollback · offline queue · conflict strategies.

Mobile geodatabase

Read .geodatabase / .mmpk offline via ST_Geometry — no ArcGIS license.
