We describe a tool, MatchMaps, that generates sameAs and partOf matches between spatial objects (such as shops, shopping centres, etc.) in crowd-sourced and authoritative geospatial datasets. MatchMaps uses reasoning in qualitative spatial logic, description logic and truth maintenance techniques, to produce a consistent set of matches. We report the results of an initial evaluation of MatchMap...

Buried military munitions, such as bombs, artillery projectiles, rockets and landmines can present serious safety hazards. Geophysical investigations are often used to detect such munitions so that they can be safely recovered and destroyed. However, different geophysical methods each have particular capabilities and limitations. Magnetometers and gradiometers are well suited to detecting ferro...

Cognitive models of orientation using aerial-view 2D diagrams such as maps could help us to predict where their contents and design help, or hinder, cognitive processes, resulting in more usable map designs for situations where orientation is a common problem. However, the complex realities of geographic space, and the large scale transformations required with maps, make it less easy to model e...

The US Army Research Lab and the Knowledge Engineering Group of the US Army Ordnance Center and School (Aberdeen Proving Grounds, Md.) have developed a visual expert system for diagnostics of the M-l tank’s turbine engine. TED (Turbine Engine Diagnostics) is currently delivered on a color laptop PC one support level behind the front lines. Pictures of the engine and graphical representations of...
