Technical note

What changes when you convert GFF to GBR

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. GBR 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. GFF is made of pixels and GBR 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 a GBR 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 GFF to begin with.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GFF data has GIS software. reaConverter renders it to GBR for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to GBR with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • 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

GFF to GBR Conversion

What are GFF files?

GFF (GSAT File Format) is a raster image format developed by Sandia National Laboratories in the United States to store images and image products from its synthetic aperture radar (SAR) systems. The name comes from the Ground-based SAR Applications Testbed (GSAT), the program in which the format was created. A file of this type consists of a header of variable length, which records the configuration and performance parameters of the instrument and the image, followed by a matrix of pixel data. The format was designed to allow custom annotation of radar images, and it has gone through several revisions as Sandia's radar programs developed. It remains the main image format of the laboratory, which keeps a large library of SAR images in this form.

What are GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.

Can reaConverter convert GFF to GBR?

Yes! reaConverter instantly converts .gff to .gbr 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 images 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 GFF to GBR it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline.
