GMTI allows users to download the x,y,z coordinates found in the tile filenames as well as surrounding tiles to show more context around an individual title. It will also convert the x,y,z coordinates to their corresponding longitude, latitude coordinates which can then be plotted in Google maps.
The x,y,z coordinates can either be manually entered or GMTI can search a hard drive for filenames that match the Google maps title filename format.
An investigator could download Google Maps tiles to get insight into what directions a person was viewing, which may indicate their whereabouts.
