Technical note

What changes when you convert ZARR 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 ZARR 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 ZARR does not survive as colour in the GBR.

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 ZARR 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

ZARR to GBR Conversion

What are ZARR files?

ZARR is an open format for storing very large multidimensional arrays of numbers, such as satellite image series, climate model output, weather forecasts, and microscope scans. A Zarr data set is cut into small chunks, and each chunk is compressed and saved on its own, so a program can read just the part it needs without loading the whole data set, and many computers can work on different parts at the same time. The format was designed for cloud storage, where data are kept as separate objects, and it is now widely used for analysis-ready geospatial data in the cloud. It is maintained by a community of developers, and an OGC community standard describes its second version.

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.
