Technical note

How FGB and GBR 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. 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.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as GBR opens on any computer and any phone. reaConverter produces those from FGB in batch, entirely offline.

  • 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

FGB to GBR Conversion

What are FGB files?

FGB is the extension of FlatGeobuf, a modern binary format for geographic vector data, created by Björn Harrtell and published as open source. A file holds a collection of features, which are points, lines, and polygons with their attributes such as names and codes, together with the coordinate system and the extent of the data. The format is built for speed: an optional spatial index, built in a smart way, lets a program pick out only the features in a chosen area without reading the whole file, and the same trick works over the internet, where just the needed bytes are downloaded. Files are written once and then read many times, which suits large collections of static data, and the format has no size limit of the kind that older formats like Shapefile have.

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.
