About ASCII Grid

Arc/Info ASCII Grid is a simple text-based raster format. Each cell value is stored as a number in a plain text file with a header describing the grid dimensions and position.

Extensions: .asc
Software: ArcGIS, QGIS, GRASS GIS, GDAL, SAGA GIS
Limitations: Very large file sizes (plain text). Single band only. No built-in compression. Slow to read for large grids.

About GeoTIFF

GeoTIFF is the standard raster format for georeferenced imagery and elevation data. It embeds coordinate system and projection metadata directly in the TIFF file.

Extensions: .tif, .tiff
Software: QGIS, ArcGIS, GDAL, ENVI, GRASS GIS, Google Earth Engine
Limitations: Large file sizes for high-resolution imagery. No built-in compression by default.
