This paper reports the initial results of an analysis of LIDAR data using statistical methods in an attempt to categorise residential and industrial buildings. Two study sites representing these two land uses are identified. 3D models for the study area are constructed using an integrated methodology utilising the building polygons from digital map data and a LIDAR Digital Surface Model (DSM). ...

This paper introduces a novel top-down approach to geospatially identify and distinguish areas of mixed use from predominantly residential areas within urban agglomerations. Under the framework of the World Bank’s Central American Country Disaster Risk Profiles (CDRP) initiative, a disaggregated property stock exposure model has been developed as one of the key elements for disaster risk and lo...

In situ electromagnetic (EM) radio frequency (RF) exposure to base stations of emerging wireless technologies is assessed at 311 locations, 68 indoor and 243 outdoor, spread over 35 areas in three European countries (Belgium, The Netherlands, and Sweden) by performing narrowband spectrum analyzer measurements. The locations are selected to characterize six different environmental categories (ru...

This study focuses on identifying source and frequency of noise pollution in Yazd, Iran. For data collection, we used two approaches: First we selected 55 monitoring stations for 122 km grid network; the distance between two stations was 2 km. Then, at the same time, we measured the sound pressure level (SPL) at main roads; the distance between two monitoring stations in this case was 1 km. Aft...

Based on the authors' fieldwork, this article examined the spatial and demographic growth of a slum community in Colombo, Sri Lanka, in association with the inhabitants' socioeconomic conditions. In this slum community, which is near the industrial and commercial centers and has developed especially since the early 1970s, most dwellers are migrants from other parts of Colombo. The increase of d...

Given terrain information and user preferences such as desired city size, Autopolis generates commercial and industrial centers, and grows areas surrounding these centers. The program also creates streets and highways, and assigns a land-use for each parcel. Compared with previous methods, Autopolis generates cities with better realism, greater detail in layout, and more design variety.
