Technical note

What changes when you convert GRIB to IGES

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. GRIB is made of pixels and IGES stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside an IGES container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the GRIB to begin with.

Map Data Workflow

From map data to a working drawing

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

GRIB to IGES Conversion

What are GRIB files?

GRIB (GRIdded Binary) is the standard format of the World Meteorological Organization (WMO) for weather and climate data laid out on a grid. It was created in 1985 by the WMO Commission for Basic Systems to replace older formats of the Aeronautical Data Format family, and it became the main way for forecasting centers around the world to share the results of their computer models. A file of this type may contain many separate records, each describing one quantity, such as air temperature, wind speed, or rainfall, for a given height and moment in time. The format is compact, which suits the huge volumes of forecast data produced several times a day. It exists in two editions, GRIB1 and GRIB2, and both can appear under the .grib extension.

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.
