Technical note

What changes when you convert GEOJSONL to IGS

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 GEOJSONL 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.

FAQ

GEOJSONL to IGS Conversion

What are GEOJSONL files?

GEOJSONL is a text format for large collections of geographic features, in which each line of the file is a complete GeoJSON feature, with its shape and attributes. A regular GeoJSON file wraps all features in a single container, so a program has to read the whole file before it can use any of them. In a line-delimited file the features are independent, so they can be read, filtered, and processed one at a time, and new features can be added at the end simply by writing another line. This makes the format popular for very big data sets and for passing data between tools in a pipeline. The same idea is described in RFC 8142, the standard of GeoJSON Text Sequences, which was published by Mapbox.

What are IGS files?

The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.
