Cement-based materials are fundamental resources used to in construction. The increase in requests for and consumption of cement products, especially in Iran, indicates that more cement plants should be equipped. This study developed a geographical information system using pairwise comparison based on grey numbers to identify potential sites in which to set up cement plants. A group of five exp...

The objective of this research is to evaluate multi-temporal RADARSAT-2 polarimetric SAR data for urban land-cover classification using a novel classification scheme. Six-date RADARSAT-2 Polarimetric SAR data in both ascending and descending orbits were acquired during June to September 2008 in the rural-urban fringe of the Greater Toronto Area. The major land-cover types are builtup areas, roa...

High-resolution visible remote sensing imagery and thermal infrared hyperspectral imagery are potential data sources for land-cover classification. In this paper, in order to make full use of these two types of imagery, a spatial-spectral-emissivity land-cover classification method based on the fusion of visible and thermal infrared hyperspectral imagery is proposed, namely, SSECRF (spatial-spe...

In this paper, the problem of the detection of road networks in high resolution Synthetic Aperture Radar (SAR) images is addressed. Our method, which is an improvement of previous work based on line extraction and connection with Markov random field, is dedicated to dense urban areas. The major modifications are, first, the introduction of a classification in order to improve both the level of ...

The first and most important step in road safety management is the identification of roads with safety needs. The most prevalent road screening technique utilizes the quality control method. Exposure data is used to estimate the expected number of crashes, which is then compared to the actual number of crashes in order to identify locations with safety needs. This approach must be modified when...

Roads are of important elements of urban infrastructure which directly and crucially affect the life of people in cities. The criticality of the roads network in urban areas justifies the efforts made to use remotely sensed data especially High Resolution Satellite Imagery (HRSI) to generate fast and accurate knowledge about road networks and to update road maps. Besides, on the way towards inv...
