is-cog
Super Light and Fast Method for Checking if a TIFF is a Cloud Optimized GeoTIFF
how does it work
- It uses id-tif to check if the file is a TIFF.
- If it is a TIFF, it uses is-geotiff to check if the file is a GeoTIFF.
- If it is a GeoTIFF, it uses has-bytes to check if the bytes associated with the following tags are present: TileWidth, TileLength, TileOffsets, and TileByteCounts.
