-    "GeoTIFFS (Geographic Tagged Image File Format (GeoTIFF)) are an image format based on the TIFF (Tagged Image File Format), that contain georeferencing information embedded within a raster image. Rasters in GeoTIFFs are made up of gridded pixels (or arrays) that map to a geographic region. The pixels values represent a characteristic (variable) for the geographic region it maps to.\n",
+    "The TIFF (Tagged Image File Format) format is a metadata rich image format for raster data. GeoTIFF (Geographic Tagged Image File Format) files are TIFF files that use georeferencing information (such as map projection and coordinate systems) as metadata. A GeoTIFF file with a single band contains 2D raster data for a single characteristic (i.e., variable) and maps to a geographic region. A GeoTIFF file can have multiple bands that all map to the same geographic region.\n",
