ACM SIGPATIAL Symposium (ACM GIS 2012)
Abstract. Geospatial data has become an important resource in today’s Web applications not only as type of content, but also as metadata. De- spite its undisputed usefulness, issues need to be addressed with respect to the availability, the accuracy, and the cost of the data. The advent of Web2.0 created several creative-commons initiatives ad- dressing geospatial dataset creation and countless (mobile) applications have been producing large amounts of point cloud datasets. In this work, we demonstrate how to query user-contributed point- cloud data using a collaborative Web-based approach.
