IMAGE QUALITY ASSESSMENT OF HIGH-RESOLUTION SATELLITE IMAGES WITH MTF-BASED FUZZY COMPREHENSIVE EVALUATION METHOD
Image Quality Assessment High-resolution Satellite Images MTF Fuzzy Comprehensive Evaluation
2018/5/15
A Modulation Transfer Function (MTF)-based fuzzy comprehensive evaluation method was proposed in this paper for the purpose of evaluating high-resolution satellite image quality. To establish the fact...
DISCUSSION ON HEIGHT SYSTEMS IN STEREOSCOPIC MAPPING USING THE ZY-3 SATELLITE IMAGES
ZY-3 Stereoscopic Satellite Mapping Geoid Ellipsoidal height Orthometric height Accuracy
2018/5/16
The ZY-3 is the civil high-resolution optical stereoscopic mapping satellite independently developed by China. It is mainly used for 1 : 50,000 scale topographic mapping. One of the distin...
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...
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...
SATELLITE IMAGES OF AIR POLLUTANTS AND LAND COVER FOR ENVIRONMENTAL EDUCATION AND DISASTER PREVENTION
Atmosphere Pollution Vegetation Volcanoes
2015/8/24
We studied the behavior of air pollutants such as volcanic gas and Asian dust by using satellite remote sensing data and ground
observations. In addition, we studied some natural disasters occurred ...
