Theoretic and Methodological Review on Sensor Information Tupu Computation
Dongping Ming · Geo-information Science · 2009
The essential issue of remote sensing application is to extract thematic information and domain knowledge from earth observation images,and thereby these information to be used in various processes of analysis and decision-making.However,information computation is the basement of the entire remote sensing application service technology system.Based on the theory of geo-informatic Tupu,we proposed the spatial cognition theory coupled with remote sensing information Tupu,constructed the theoretical and methodological system of remote sensing information Tupu in the way of pixel-object-target-pattern,which can be divided into two levels of pixel-level and object-level.This paper also discussed the idea of the designing and developing the remote sensing Tupu computation platform based on the high performance computation environment,and summarized the developing trend and important research issues of remote sensing information Tupu computation.
