Technical note

Before you convert HGT to GLB

HGT files have no header. Each tile's position is encoded only in its name: N45E006.hgt is the one-degree square whose south-west corner sits at 45° north, 6° east. The resolution is read from the file size, 3601 by 3601 samples for 1 arc-second SRTM and 1201 by 1201 for 3 arc-second. A renamed tile can no longer be placed, or even recognised, so keep the original name on anything derived from it. HGT is made of pixels and GLB 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 GLB container.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to GLB 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.

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!
