Technical note

KMZ to IGS: what to expect from the conversion

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. KMZ is one of the few GIS formats that stores its own styling: colours, line widths, placemark icons, labels and a folder hierarchy. IGS has no place for most of it, so the geometry and names come across while the look of the map does not. Placemark descriptions written in HTML arrive as raw markup in an attribute field.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as KMZ 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.
