Technical note

How ACE2 and JP2 differ in practice

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. JP2 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 JP2 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 a JP2 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 JP2 opens on any computer and any phone. reaConverter produces those from ACE2 in batch, entirely offline.

  • Render every file in a folder to JP2 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.

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!

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

ACE2 to JP2 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 JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.

Can reaConverter convert ACE2 to JP2?
