2018/5/16
The ZY-3 is the civil high-resolution optical stereoscopic mapping satellite independently developed by China. The ZY-3 constellation of the twin satellites operates in a sun-synchronous, near-polar, ...
AN IMPROVED DEM CONSTRUCTION METHOD FOR MUDFLATS BASED ON BJ-1 SMALL SATELLITE IMAGES: A CASE STUDY ON BOHAI BAY
Mudflats BJ-1 image Waterline detection method Tidal grid model DEM
2018/5/15
The topographic measurement of muddy tidal flat is restricted by the difficulty of access to the complex, wide-range and dynamic tidal conditions. Then the waterline detection method (WDM) has the pot...
COMPARISON OF THE LINEAR AND THE NON-LINEAR BLOCK ADJUSTMENT ON SATELLITE IMAGES RESEARCH
Linear Least square method Non-Linear Least square method error equation Block adjustment Rational Function Model High-resolution Satellite images
2018/5/14
The Rational Function Model （RFM） is a non-linear model. Usually, the RFM-based satellite image block adjustment uses the Taylor series to expand error equations, and then solves the linear model. The...
A NOVEL TWO-COMPONENT DECOMPOSITION FOR CO-POLAR CHANNELS OF GF-3 QUAD-POL DATA
GF-3 satellite, Model-based decomposition, Two-component decomposition, Co-polar data, PolSAR
2018/5/14
Polarimetric target decomposition theory is the most dynamic and exploratory research area in the field of PolSAR. But most methods of target decomposition are based on fully polarized data (quad pol)...

BUILT-UP AREA DETECTION FROM HIGH-RESOLUTION SATELLITE IMAGES USING MULTI-SCALE WAVELET TRANSFORM AND LOCAL SPATIAL STATISTICS
Built-up Area Detection High-resolution Satellite Image Wavelet Transform Local Spatial Statistics
2018/5/11
Recently, built-up area detection from high-resolution satellite images (HRSI) has attracted increasing attention because HRSI can provide more detailed object information. In this paper, multi-resolu...
ESTIMATION OF SATELLITE-BASED SO42− AND NH4+ COMPOSITION OF AMBIENT FINE PARTICULATE MATTER OVER CHINA USING CHEMICAL TRANSPORT MODEL
PM2.5 chemical components sulfate ammonium satellite-estimated chemical transport model
2018/5/15
Epidemiologic and health impact studies have examined the chemical composition of ambient PM2.5 in China but have been constrained by the paucity of long-term ground measurements. Using the GEOS-Chem ...
