摘要

Due to the increasing volume of spatio-temporal data generated from remotesensing, sensor networks and computational simulation, there is a need for a generic,domain-independent framework for spatio-temporal data analysis. This researchpresents a generic set of data processing and manipulation tools for spatio-temporalraster data called multidimensional map algebra (MMA). MMA is an extension ofconventional map algebra that operates not only on data that are two-dimensionalin space but also on data that are: (1) one-dimensional in time; (2) both two-dimensional in space and one-dimensional in time; (3) three-dimensional in space;and (4) both three-dimensional in space and one-dimensional in time. MMA datatypes, neighborhoods, lags, and functions are presented, including rules for combin-ing data types of different dimensionality within local, focal, and zonal functions. Aprototype implementation in JAVA is provided as a demonstration and syntaxspecification for the functions. Challenges to continued development of MMAinclude performance and efficiency issues for processing very large multidimensionaldata sets.
