High mortality rates and lack of recruitment in the acacia populations throughout the Negev Desert and the Arava rift valley of Israel have been reported in previous studies. However, it is difficult ...
Extended morphological profile (EMP) is a good technique for extracting spectral-spatial information from the images but large size of hyperspectral images is an important concern for creating EMPs. H...
Digital Elevation Model (DEM) is indispensable for many analyses such as topographic feature extraction, runoff analysis, slope stability analysis and so on. Beforehand such analyses, accuracy of DEM ...
In this paper we present a quality evaluation of two-dimensional building acquisition. We propose methods for identification and quantifi-cation of differences between independently acquired regions, ...
The determination of the spatial extent of geo-objects is generally approached through the boundaries or more precisely through the position of the boundary points. The analysis of the geometric uncer...
This paper presents the first results of a study which investigates river basin water quality management based on the ability of GIS to integrate different data sources into a common geographical data...
The southern part of the Alps is interested by frequent avalanche phenomena. It is very important to provide a suitable method to manage avalanche risk. The usual approach is based on the mapping of t...
Analyzing the law of economic development and estimating the regional economy development’s level to discover the relation between the economy development and area diversity, which can providethe refe...
Ground spatial data acquisition is a key technology in digital city engineering, It is important to improve the efficiency of data acquisition. The main purpose of this paper is to develop vehicle-bor...
Following the development of spatial information acquisition technology, more and more spatial data have been collected through various approaches. There has been a full utilization of geospatial info...
Mumbai city has become extremely vulnerable due to a large population living in huts especially in low-lying areas. Whenever city receives heavy rains; roads get waterlogged and the traffic is disrupt...
Recently, it is required to investigate the spatial distribution of vegetation in urban areas on a regional scale for not only the improvement of urban environment but also the conservation of ecosyst...
Within the scope of processing large amounts of data and complex calculations the use of grid computing is a good choice for achieving high performance, because processing of extensive spatial data ca...
Tremendous amount of spatial data reside in operational or legacy data stores of public and private institutions. These databases contain topographic maps, aerial photos, satellite images, medical dat...
As the Geospatial Technology (GT) grows, the generation and utilization of 3D city spatial model are actively studied. In some applications, the fundamental model is too detail comparing with the leve...
