Iii: Small: A Theory Of Topological Relations For Compound Spatial Objects, Max J. Egenhofer Editor

University of Maine Office of Research Administration: Grant Reports

Spatial data collections with an incomplete coverage yield regions with holes and separations that often cannot be filled by interpolation. Geosensor networks typically generate such configurations, and with the proliferation of sensor colonies, there is now an urgent need to provide users with better information technologies of cognitively plausible methods to search for or compare available spatial data sets that may be incomplete. The objective of the investigations is to advance knowledge about qualitative spatial relations for spatial regions with holes and/or separations.

The core activity is the study of the interplay between topological spatial relations with holed regions and …

Toward A Commons Of Geographic Data, Joseph J. Campbell

Electronic Theses and Dissertations

Making scientific data openly accessible and available for re-use is desirable to encourage validation of research results, and/or economic development. A significant body of spatially-referenced, locally-produced data produced by individual researchers, non-profit groups, private associations, small companies, universities, and non-governmental organizations across the United States is not online and therefore not generally available to professional scientists and to the general public. If there were an online environment, a "Commons of Geographic Data," where that data could be deposited or registered, and where users could access and re-use it, what infrastructure characteristics might potential contributors find desirable in order for them …
