FAQ
ASC to FLIF 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 FLIF files?
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
