Looking into the google earth possibilites,... the problem with that is that google earth doesn't really sync up with a gps .... right now the most promising software I have come accross is this
TNC Invasive Species Initiative page
it syncs with gps, can produce maps, and excel reports, and furthermore its actually designed around the idea of tracking invasive species ( or weeds as they call them ) this seems ideal as it will also serve as a database for invasive species, and we can track our progress over the course of time. It can also be run on ppc for use in the field.
Has anyone had any experience with this software ? or know of any other similar programs ? Any GPS enthusiasts here ?
