Forumites I wanted to find out more about GPS units, a topic many people have asked about on this listserv in the past. What I am trying to figure out is the accuracy between an item like the Trimble Geo-Explorer XT compared to something more economically available like a Garmin 12 or Magellan product? Are people happy using simple GPS units like the Garmin 12 to collect data especially if you want to conduct geospatial analyses and if so how do you deal with spatial accuracy and post processing data if it can be done. Also, what is the spatial accuracy compared to sub-meter GPS units. I would assume that it couldnt but it might also be difficult to do. I know the Trimble GPS unit and Pathfinder Office makes this easier and you have better accuracy and precision, you even get a root mean square error with you data so that could be discussed. I appreciate any input and help from any one and look forward to hear what has to be said. You can reply to me and then I can summarize what was said to the listserv if need be.
