FAQ

ASC to QRT 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 QRT files?

The QRT format file is associated with the QRT Ray Tracer, also referred to as Quick Ray Tracer. QRTs are uncompressed raster graphic images which contain 3D scenes for ray tracing. Although they haven't been used very frequently in past years, they can be used for various rendering applications.
