Technical note

ASC to TGA: what to expect from the conversion

Every cell in an ASC 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. TGA 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 TGA returns a shade, not an altitude. ASC carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. TGA has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the ASC original if the data still has to go back into a GIS.

FAQ

ASC to TGA Conversion

What are ASC files?

The ASC (Esri ASCII Grid) format stores raster geospatial data as plain text. Developed by the Environmental Systems Research Institute (ESRI), it describes a rectangular grid of cells using a short header — number of columns and rows, coordinates of the lower-left corner, cell size and a no-data value — followed by the cell values themselves, written row by row as ordinary numbers. Because the entire grid is human-readable text, ASC is widely used for exchanging elevation models, slope maps and other continuous surfaces between GIS packages that would otherwise share no common binary format.

What are TGA files?

The TGA (Truevision Graphics Adapter) format, also known as Truevision TGA or TARGA, is a bitmap file containing raster graphics and was initially associated with TARGA and VISTA boards. TGA files can be used on DOS, Windows and Mac OS X platforms for storing and transferring deep-pixel images. They support a color range of up to 24 bits and an 8-bit alpha channel. TGA files are associated with graphic adapters that can capture NTSC and/or PAL video images signals, and they are particularly popular in the domain of still-video editing.
