Technical note

GSB to IGES: 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. IGES 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. A line in a GSB image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the GSB does not survive as colour in the IGES.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as GSB and end up in IGES. 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 IGES 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.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

GSB to IGES Conversion

What are GSB files?

GSB (Grid Shift Binary) is the file extension of the NTv2 format, short for National Transformation version 2, developed in Canada by Natural Resources Canada for converting map coordinates from one geodetic datum to another. When old maps were based on one model of the Earth and new surveys use another, the same place ends up with slightly different coordinates, and a file of this type records how far each point has to move. It covers an area with a net of points and stores the shift in latitude and longitude at each of them, usually together with an estimate of the accuracy. The format later spread to other countries, including the United Kingdom, Switzerland, and Australia, and it is widely used in surveying, cadastre, and GIS.

What are IGES files?

IGES (Initial Graphics Exchange Specification) is a widely used file format for exchanging 2D and 3D CAD data between different design and engineering software. It supports wireframe, surface, and solid models, making it a common standard in mechanical, aerospace, and automotive industries.
