02CadGis - CAD/GIS Importer
Convert MS Access (.accdb, .mdb), ArcGIS File Geodatabase (.gdb), Google Earth KML/KMZ, AutoCAD DWG/DXF, Shapefile, GeoJSON, GML, CSV, GPX and MicroStation DGN to GeoPackage in a few clicks: preview the layers inside, keep the ones you need, reproject, filter hundreds of files by extent and export back to DXF, KML/KMZ or MBTiles.
02CadGis is a conversion studio for the files GIS work keeps receiving: Microsoft Access databases (.accdb, .mdb) and ESRI Personal Geodatabases, ArcGIS File Geodatabases (.gdb), Google Earth KML and KMZ, AutoCAD DWG and DXF drawings, Shapefiles, GeoJSON, GML, CSV/TSV with X/Y or WKT columns, GPX tracks, SpatiaLite, MapInfo TAB/MIF, FlatGeobuf and MicroStation DGN. Drop a file on the dock, see every layer with its geometry type and feature count, tick the ones you need and get one clean GeoPackage, or add large Geodatabase layers live without copying.
Along the way it reprojects, splits CAD drawings by layer or level, keeps CAD elevations, labels texts, expands KML balloon tables into real fields and turns KMZ ground overlays into GeoTIFFs. The Batch Spatial Extent Filter scans hundreds of drawings and datasets and keeps only those that touch your study area. The other direction works too: QGIS layers export to DXF, KML/KMZ or MBTiles/XYZ tiles, and three Processing tools make the steps scriptable.
Older DWG files (up to R2000) open directly; newer DWG versions need the free ODA File Converter or LibreDWG's dwg2dxf. Access files need the free Microsoft Access Database Engine on Windows. Regional extras: Netcad NCZ/NCA drawings and Turkish imar (zoning) plan styling with MPYY (QGIS 3.30 or newer).
