FAQ
ASC to PNG 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 PNG files?
The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.
