Convert GVB to IGES

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

Batch GVB to IGES conversion doesn't have to be complicated. reaConverter processes entire folders with consistent quality settings. Works offline with no internet required, so you can convert anywhere, anytime. Surveyors and planners use it to pass GIS data to colleagues who work in other software.

Technical note

How GVB and IGES differ in practice

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. How good the result is depends almost entirely on the GVB going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

Map Data Workflow

From map data to a working drawing

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

FAQ

GVB to IGES Conversion

What are GVB files?

GVB is a datum grid shift file that follows the NTv2 (National Transformation version 2) model, created by the Geodetic Survey of Natural Resources Canada. Such a file helps convert map coordinates between two geodetic datums, which are different mathematical models of the Earth, so that old and new survey data line up correctly. It covers an area with a net of points and stores, for each of them, how far latitude and longitude have to be moved, usually with an estimate of the accuracy of the shift. A program finds the points nearest to a location and calculates the exact correction between them. Files with this structure are used by national mapping agencies and surveyors, and they are particularly valuable for cadastral and engineering work, where small errors matter.

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.
