Reply to "What is GIS?"

GIS is new to me. I expect the raw data is the same as what we see on Google Earth, and I'd expect the same level of accuracy.

I did a search and got:

GIS Mapping

I would be reluctant to accept this as equal to a competently-done bike measurement. One drawback is that the certifier would be presented with a take-it-or-leave-it pile of data.

There may be information relating to the accuracy of the method, but until such is presented and made understandable and credible, I do not believe we should accept it for course certification.
