PAIRWISE-SVM FOR ON-BOARD URBAN ROAD LIDAR CLASSIFICATION
LiDAR on-board classifiaction SVM MRF
2016/7/4
The common method of LiDAR classifications is Markov random fields (MRF). Based on construction of MRF energy function, spectral and directional features are extracted for on-board urban point clouds....
PERFORMANCE OF TDVI IN URBAN LAND USE/COVER CLASSIFICATION FOR QUALITY OF PLACE MEASUREMENT
PERFORMANCE URBAN LAND USE COVER CLASSIFICATION QUALITY OF PLACE MEASUREMENT
2015/12/31
Measuring the Quality of Place (QOP) is a hard task since it involves both physical and socio-economic dimensions. Being one of the major land use categories, urban vegetation plays a significant role...
SURFACE URBAN HEAT ISLAND IN SHANGHAI,CHINA:EXAMINING THE RELATIONSHIP BETWEEN LAND SURFACE TEMPERATURE AND IMPERVIOUS SURFACE FRACTIONS DERIVED FROM LANDSAT ETM+ IMAGERY
Land Surface Temperature Impervious Surfaces Linear Mixture Spectral Analysis Urban Heat Islands Shanghai
2015/12/28
This paper investigates the relationship between the surface urban heat islands (SUHI) and the percent impervious surface area (%ISA) in Shanghai, China. The %ISA was characterized from a Landsat-7 ET...
ANALYSIS OF VEGETATION DISTRIBUTION IN URBAN AREAS: SPATIAL ANALYSIS APPROACH ON A REGIONAL SCALE
