# File formats

# Importable file formats

### Upload panel

###### Datasets

* Need to be in a global coordinate system and assigned height reference system, and compressed into one ZIP file
* ZIP file maximum size 2GB & amount of points 50 million

**Supported 3D model formats**: .obj & .ifc

If the .obj file includes textures, include also the .mtl and .png/.jpeg -files to the same compressed ZIP file, if they exist.

# Import geospatial file formats

You can import geospatial files in various places within the GISGRO system. Some file formats do not contain coordinate system information. In these cases, your Port’s coordinate system is used. The following sections describe details about the specifics of the file formats supported by GISGRO.

### GeoJSON

GeoJSON files can optionally contain a coordinate reference system definition. If it’s used, then GISGRO will use the CRS reported in the file. Otherwise, GISGRO will use the World Geodetic System 1984 (WGS 84) datum, with longitude and latitude units of decimal degrees as specified by IETF RFC 7946.

### DXF

GISGRO supports reading DXF files generated by all recent versions of AutoCAD. Any arcs, ellipses, circles and rounded polylines are approximated with respective linestring geometries. Hatches are imported as areas (polygons) in GISGRO. Any block references within DXF files are expanded with the geometry of the block they reference.

||| Styling information for geometries is generally lost when importing them from DXF files.

|| Since DXF doesn’t support georeferencing, the organisation’s coordinate reference system is used when importing DXF files.

### DWG

GISGRO supports all versions of DWG file formats all the way up to DWG 2018 (AC1032) both in binary and ASCII format. Any arcs, ellipses, circles and rounded polylines are approximated with respective linestring geometries. Hatches are imported as areas (polygons) in GISGRO. Any block references within DWG files are expanded with the geometry of the block they reference.

||| Styling information for geometries is generally lost when importing them from DWG files.

|| Since DWG doesn’t support georeferencing, the organisation’s coordinate reference system is used when importing DWG files.

### DGNv8

GISGRO supports the DGN v8 file format. Generally speaking, any concept of complex objects, and cells as associated components is lost. Each component of a complex object or cell is imported as an independent feature. Any arcs, ellipses, circles and rounded polylines are approximated with respective linestring geometries. Shape and ComplexShape objects are imported as areas (polygons) in GISGRO.

### ESRI Shapefile

ESRI Shapefiles are supported for points, linestring and area (polygon) geometries. Since ESRI Shapefiles consist of multiple files, they can be uploaded to GISGRO by firstly combining them to a zip archive and then uploading the zip to GISGRO.
