Abstract :
How does one effectively manage spectral data to find information oriented subjects? How does one mine the spectral data in observation intervals from data in existence? In this paper, a tree data structure, which includes dimension tables and fact tables, is presented to establish the top architecture and tie together the various data tables, for instance, spectrum data and its interrelated matching parameters. A new method on mining canopy spectra in observation intervals is discussed, which is based on certain crop models and the tree structure data warehouse. At last, a case on vegetation spectral simulation is given to test the structure of a data warehouse and to verify the data mining method using SE590 data obtaining during the field experiment conducted from March to May 2001 in Shunyi, Beijing, China (40°00´-40°18´N, 116°28´-116°58´E).
