Technical note

BYN to STP: what carries over and what does not

BYN is made of pixels and STP 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 an STP container.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to STP 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.

reaConverter handles STP file conversion excellently. The batch processing feature is perfect for converting multiple CAD files at once, and the drag-and-drop interface makes it super easy to use. Quality is preserved well during conversion, and it supports plenty of output formats. Recommended for engineers and designers.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

BYN to STP Conversion

What are BYN files?

BYN is a binary grid format developed by the Canadian Geodetic Survey of Natural Resources Canada (NRCan) to distribute geoid models and height conversion grids, such as CGG2013a and HT2_0. A file of this type stores a regular grid of geoid heights, which allows ellipsoidal heights obtained from GNSS measurements to be converted into heights above the Canadian Geodetic Vertical Datum of 2013 (CGVD2013). The file consists of an 80-byte header and a data section. The header gives the grid boundaries and spacing in arc-seconds, the size of each value, and a scale factor, while the data section holds whole numbers instead of decimals, which keeps the file compact. Companion files with the .err extension use the same structure to describe the accuracy of the model.
