Based on RS and GIS, took 1993, 2000, 2007 and 2009 TM images as the data source, classic area (CA), pieces of Percent of landscape (PLAND), plaque number (NP), patch density (PD), largest patch index (LPI), shape index (LSI), fractal dimension (PAFRAC) were used to analyze the change of landscape from the types of Tangshan coal mining subsidence landscape. Landscape characteristics and dynamics change...
For the large-scale acquisition of hyperspectral or multispectral images, data distribution challenges the capabilities of available transmission technologies. It is therefore common to include data compression as part of a distribution system for remotely sensed imagery. While individual images can be compressed for transmission by taking into account the inherent spatial and spectral redundancy,...
