Remotely sensed multi-spectral and -spatial data facilitates the study of mosquito-borne disease vectors and their response to land use and cover composition in the urban environment. In this study we assess the feasibility of integrating remotely sensed multispectral reflectance data and LiDAR (Light Detection and Ranging)-derived height information to improve land use and land cover classific...

We developed a Sub-pixel Imperviousness Change Detection (SICD) approach to detect urban land-cover changes using Landsat and high-resolution imagery. The sub-pixel percent imperviousness was mapped for two dates (09 March 1993 and 11 March 2001) over western Georgia using a regression tree algorithm. The accuracy of the predicted imperviousness was reasonable based on a comparison using indepe...

Web-based 3D GIS becomes one of the major areas of GIS research, which extend distributed virtual geographic environment when integrated with virtual reality. Distributed virtual city environment, one of the most important research fields, will meet the demands of the urban planning and urban landscape. Firstly, a CORBA-based distributed architecture is presented. Secondly, a new 3D LOD buildin...

The past few years have witnessed a proliferation of studies using spatial metrics to examine spatial structure of land cover change. Urban analysts are no exception, applying landscape metrics to study and model patterns of urban growth. While the majority of this research examines emerging urban structures by measuring changes in their aggregate forms, these spatial patterns are often dominat...

logistic regression (lr) was used to model urban growth between the years 1987 and 2001 in gorgan city, north east of iran. three groups of variables including economic-social, land use and biophysical variables were used in the modeling practice. using covariance of the independent variables, distance to administrative and sporting centers plus distance to cities were removed. roc (relative op...
