With the rapid development of data observation and model simulation in geoscience, spatial-temporal data have become increasingly multidimensional, massive and are consistently being updated. As a result, the integrated maintenance of these data is becoming a challenge. This paper presents a blocked hierarchical tensor representation within the split-and-merge paradigm for the compressed storage,...
Modeling dynamics of complex geographical phenomena is of lots of difficulties in current GIS system. In this paper, Spacetime algebra, a powerful algebra system in expression and analysis of the unified spacetime, is introduced in modeling the dynamics of geographical objects. The basic structure of spacetime algebra and its design schemes are discussed. Case application with satellite altimetry...
