Technical note

What changes when you convert GTX 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. A line in a GTX 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 GTX does not survive as colour in the GBR.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GTX 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

GTX to GBR Conversion

What are GTX files?

GTX is a grid file used by NOAA's VDatum software to convert heights from one vertical reference to another. Heights on maps can be measured from different surfaces, such as the ellipsoid used by satellite positioning, the geoid that approximates mean sea level, or a tidal level like mean lower low water, and the difference between these surfaces changes from place to place. A file of this type covers an area with a regular net of points and stores the height difference at each of them, so that a program can add it to a measured height and obtain the value in the other system. Earlier versions were text files, while current ones are binary. The format is also used for global geoid models and for national height transformations.

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 GTX to GBR?

Yes! reaConverter instantly converts .gtx 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 GTX 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 GTX 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. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.

Why choose offline conversion with reaConverter?
