Map Data Workflow

From map data to a working drawing

Converting GTI to DGN usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • Convert every layer in a folder to DGN with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

FAQ

GTI to DGN Conversion

What are GTI files?

GTI (Raster Tile Index) is a small file that turns a large collection of map or image tiles into one seamless virtual picture. Instead of storing any pixels, it points to the individual raster files, which may be aerial photographs, satellite scenes, or terrain tiles, and describes where each of them lies on the map. A program that opens the GTI file sees one continuous image and loads only the tiles needed for the visible area, which makes it practical to work with archives of thousands of files without merging them first. The format appeared in 2024 and is stored as a short XML file with the .gti extension, or as a tile index in a GeoPackage or FlatGeobuf file.

What are DGN files?

DGN stands for "design" and represents an extension typically used for CAD (Computer Aided Design) files created with Bentley Systems' MicroStation or with IGDS (Intergraph's Interactive Graphics Design System) — two popular programs used by architects, engineers, constructors and designers. DGN files can include sizeable building projects with a rich amount of details, usually have a very large size and can be viewed with a limited number of CAD programs.
