Technical note

How ZARR and STEP differ in practice

ZARR is made of pixels and STEP is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a STEP container.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to STEP 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 STEP 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.
