Convert THF to GBR

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

Batch THF to GBR 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 THF 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 THF 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

THF to GBR Conversion

What are THF files?

THF is the main file of a package in EDIGEO, the French standard for exchanging digital geographic data, and it is best known from the French cadastral plan, the digital map of land parcels that the tax administration makes available for every commune. A single EDIGEO delivery is made of several files with the same base name, and the THF file is the one that stands at the top: it describes the transfer as a whole and tells which other files belong to it. By itself it holds no map, and the parcels, buildings, and boundaries are in the other files of the package. Such packages are published openly for the whole of France and are widely used to produce local maps and to import cadastral data into other systems.

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.
