road extraction road connection K-mean cluster high spatial resolution
2015/12/23
For the significance of road information to the city management, urban roads are subjects of great concern to be extracted from remotely sensed images. With the availability of high spatial resolution...
CHANGE DETECTION BASED ON PERSISTENT SCATTERER INTERFEROMETRY–CASE STUDY OF MONITORING AN URBAN AREA
Persistent Scatterer Interferometry (PSI) Change Detection Urban Monitoring
2015/9/21
Persistent Scatterer Interferometry (PSI) is a technique to extract subtle surface deformation from sets of scatterers identified in time-series of SAR images which feature temporally stable and stron...
COMPARING FREQUENCY-BASED MEASURES OF SPECTRAL AND MORHPOLOGICAL DIVERSITY WITH SOCIODEMOGRAPHIC CHARACTERISTICS IN AN URBAN AREA
frequency-based contextual classification urban morphometry housing crime lidar
2015/8/3
Remotely-sensed imagery has a demonstrated connection to urban demographic variables. In a previous study, frequency-based contextual counts of cover type classes have been related to census housing v...
