Technical note

MRF 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. A line in an MRF 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 MRF does not survive as colour in the IGS.

Map Data Workflow

From map data to a working drawing

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

MRF to IGS Conversion

What are MRF files?

MRF (Meta Raster Format) is a format for very large images, such as global satellite mosaics, that was developed at NASA's Jet Propulsion Laboratory to serve maps to web browsers quickly. The picture is divided into many small square tiles, and the tiles are stored at several levels of detail, from the whole image at full resolution down to small overviews. A viewer needs to load only the few tiles that are visible, which makes it practical to browse images of enormous size. An MRF dataset is made of three files: a small readable file with the .mrf extension that describes the image, a data file with the tiles, and an index file with the .idx extension that tells where each tile is. NASA uses the format for its Global Imagery Browse Services, and Esri has helped to develop it further.

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.

Can reaConverter convert MRF to IGS?

Yes! reaConverter instantly converts .mrf to .igs with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert MRF files directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them. For MRF to IGS it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.

Why choose offline conversion with reaConverter?
