Convert GML to IGS

Online GIS converters cap file size and need an upload. reaConverter converts GML to IGS locally, whatever the size of the dataset.

Online converters too slow for your GML files? reaConverter works locally and handles unlimited batches. All processing runs locally on your PC, so your files stay private and secure. Works without QGIS or ArcGIS, so GIS data can be converted on any office PC.

Technical note

GML to IGS: what carries over and what does not

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. IGS expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as GML and end up in IGS. reaConverter turns the layers into drawing entities in batch, so a full project folder moves across in one run.

  • Convert every layer in a folder to IGS 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.
