Questions & Answers
ACE2 files: Frequently Asked Questions
What are ACE2 files?
ACE2 (Altimeter Corrected Elevations DEM) is a binary raster format for the second-generation global Digital Elevation Model produced by ESA and De Montfort University. The file stores a matrix of little-endian Float32 elevations in which SRTM surface features are corrected with re-tracked altimetry from the ERS-1, ERS-2, Envisat, and Jason satellites, extending coverage beyond the 60-degree latitude limit; quality, source, and confidence layers are stored as Int16 arrays. The format has no header, so tile bounds and cell size are derived solely from the filename. For graphics output, elevations are rescaled to 8-bit or 16-bit grayscale, colorized with a hypsometric ramp, or rendered as shaded relief in PNG, JPEG, or TIFF, while GeoTIFF preserves the full floating-point values. Global Mapper, ArcGIS Data Interoperability, and Manifold GIS can export ACE2 grids for hydrology, flood risk assessment, and terrain visualization.
