Spatial Accuracy 2.0

University of California, Santa Barbara
Abstract. Research on spatial accuracy assessment occurs within a broader context that provides its motivation. That broader context is dynamic, and has been changing at an accelerating rate. The concept of the Geospatial Web imagines a world of distributed, interoperable, georeferenced information in which it is possible to know where everything of importance is located in real time. It assumes an ability to conflate that is far beyond today’s capabilities. Web 2.0 describes a substantial involvement of the user in creating the content of the Web, and has particular relevance to geospatial information. Metadata 2.0 shifts the onus for metadata production to the user, and addresses some of the growing issues surrounding existing standards. There is a growing need to address the accuracy assessment of the vast quantities of geospatial data being contributed by individual Web users.
