tiff to kml conversion is most likely related to export of GIS Imagery (exported maps to TIFF format) to Google Earth's KML/KMZ format. Can be also used as basis for making rendering of 3D topography or similar purposes. Most GIS tools actually support geoTIFF files, which are a special type of TIFF images with additional metadata. This means that not every TIFF is suitable for such export.
