Seems like a bit of an odd question but it's a good one. We need to be asking it more often. At the heart of it is a common concern - what needs and questions can be appropriately answered with a given GIS dataset. The things we map change. A small stream today can be a sizable river in the rainy season. Today's GIS community wants to build and use "live maps" that address these dynamic issues as opposed to "dead maps". To complicate matters, we are looking to to inject Volunteered Geographic Information (VGI), citizen science data or sensor content from the Internet of Things (IoT) into our enterprise geospatial systems. This requires us to evaluate how good an open source data set is in comparison to our base information prior to ingesting it into our enterprise GIS. What it comes down to is that we have no way to quantitatively measure quality, until now.
