My research interests center on the spatial concepts of GIScience, including Geographic Information Systems (GIS), remote sensing and their applications. In particular, I'm interested in the effect of scale and spatial homogeneity in modeling physical geographic phenomenon. During my daydreaming, all spatial models utilize remotely sensed / GPS data in an open-source, open-standard GIS for analysis and communicate the result in real-time with the audience through distributed GIServices on the Internet all in a seamless fashion.
