Footprints is a geo-tagging program I think. It uses your GPS to tag pictures you take as far as where you are and stuff like that.

"HTC FootPrints lets you create a diary of places and events. So on one screen you can have a photo, the location (even GPS tagged), voice notes, the time/date, written notes and a phone number so you can create a diary of events. So if you go on a trip or if you just want to remember a restaurant location this is a pretty slick piece of software. It links with GoogleMaps as well as TomTom, CoPilot, PaPaGo and NaviTel but you do not need any of those GPS applications to use it. If you want Google Maps to work with it then you need to install FootPrints first and then GMaps else the GMaps icon will not appear. HTC FootPrints will install into Programs/MultiMedia. This was ported by KDKobesfrom xda-developers."
