. Most of you are familiar with GPS, right? So, GPS is really just a means to find out “where you are”, or, in the case of acquiring map data, “where you were”. In EAST, students primarily use GPS to gather map data that aren’t available from other sources, such as the Internet. What they do with the data after they gather it is really the key, and that is where GIS comes into play.
Here’s an example from Russellville High School, where students used GPS to add map features for their school to a digital aerial photograph.
In another example, also from Russellville, students took a GPS unit in a car and drove a new segment of road,
providing updated data for their street map.
