Technical note

ACE2 to AVIF: what carries over and what does not

Every cell in an ACE2 file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. AVIF stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the AVIF returns a shade, not an altitude. Missing cells in an elevation grid, such as water, radar shadow or the edge of a survey, are not empty: they hold a sentinel value, -32768 in SRTM, -32767 in DTED and very often -9999 in ESRI grids. Counted as a real height, that value stretches the scale so far that the actual terrain collapses into a few near-identical shades. When an AVIF output looks flat and washed out, a void treated as data is the usual cause.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as AVIF opens on any computer and any phone. reaConverter produces those from ACE2 in batch, entirely offline.

  • Render every file in a folder to AVIF 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.

Google Photos auto-saved my pics as AVIF files that won’t open anywhere. reaConverter rescued 3 years of memories AND kept the quality. Take that, ‘innovation’!

Twitch thumbnails keep saving as AVIF and my editing software freaks out. reaConverter swaps them to JPEG instantly. Now I can actually post my ‘🔥HOT TAKES🔥’ without crying over file errors.

FAQ

ACE2 to AVIF Conversion

What are ACE2 files?

ACE2 is a raw binary raster format used to distribute the Altimeter Corrected Elevations (Version 2) global Digital Elevation Model (DEM), developed through a synergistic fusion of the Shuttle Radar Topography Mission (SRTM) dataset and multi-mission Satellite Radar Altimetry. Distributed primarily as 15 by 15 degree geographic tiles, a file of this type contains matrix elevations with spatial resolutions available at 3, 9, and 30 arc-seconds, as well as 5 arc-minutes. The format inherently lacks embedded geospatial metadata, meaning its exact georeferencing and spatial bounds are determined entirely by standard filename conventions referencing the southwestern edge of the southwestern-most pixel. Native compliance allows these files to be seamlessly integrated into specialized environmental, climate, and terrain modeling software.

What are AVIF files?

AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency. Multiple graphics compression tests show that the .avif format outperforms the JPEG, PNG and WebP image formats for its image quality to compressed file size ratio.

Can reaConverter convert ACE2 to AVIF?

Yes! reaConverter instantly converts .ace2 to .avif with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.
