• METADATA & DATA INTEGRITY •
Rounding up reference data for use in a geographic information system requires the same scepticism as a conventional literature review.
The same is true if you plan to use a mobile ap or Internet GIS as an information source. The spatial databases behind Internet-based geographic information systems and map services are as vulnerable to errors and omissions as databases created by you and me. If we want to use these tools, we need to be alert to data integrity issues and participate in the feedback process offered by the database owners.
That Darned Lake
A non-existent lake shows up on a number of reputable web maps and map services. It's just our luck that someone plunked it down right next to our Wabikon Forest Dynamics Research Plot. We have a web page devoted to our efforts to get the error corrected.
