Finding Structures in Weather Maps

We describe an eeective computational method for extracting structural information from spatial data sets. For instance, the structural information such as the location, shape, size, and movement about pressure cells and troughs are important for weather prediction. We are interested in extracting these structures and representing them at aggregate levels where salient geometric features are hi...

For those people who are visually impaired or blind there are tactile maps that can be read by touch. Like in visual maps, the tactual entities representing geographical features have to be carefully selected and placed on the map with respect to technical and sensory considerations, i.e. abstraction. A schematic map is abstracted beyond technical needs. It can support map-readers to better gra...
