Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your HGT files into AI without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

How HGT and AI differ in practice

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. Lettering in the image is traced as shapes, not recognised as text. Every character arrives as an outline that can be scaled and edited like any other geometry, but not retyped, restyled or searched, and no font is attached to it. Titles and callouts on a scanned drawing usually have to be typed again in the AI if they need to stay editable.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to AI 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.
