Landfill siting should take into account a wide range of territorial and legal factors in order to reduce negative impacts on the environment. The suitability of selected site for disposal center affects the amount of generated energy and the cost of disposal generation. Suitable sites should be determined on the basis of technical, economical and socio-environmental issues. GIS along with appr...

Recent developments of GSM technology enable new applications in distributed GIS and LBS so as to provide more relevant active service to the mobile user. Specifically, the visualization of the spatial data is very important for mobile devices that have limited display capacity. The visualization problems are mostly dealt with generalization algorithms such as displacement, simplification and a...

This paper aims to incorporate intelligent mechanisms based on Soft Computing in Geographical Information Systems (GIS). The proposal here is to present a spatio-temporal prediction method of forestry evolution for a sequence of binary images by means of fuzzy inference systems (FIS), genetic algorithm (GA) and genetic programming (GP). The main inference is based on a fuzzy system which proces...

Context based classification is an important field of study in digital image analysis. Neighbouring pixels may possibly have almost equal grey values. The information of local homogenous patterns in a patch based landscape organisation has lead to studies, assuming the organisation of landscape patterns as being a complex of local spectral distributions. Image segmentation techniques are well k...

We introduce a new method to compute plant distribution in Ethiopia under paleoclimatic conditions using fuzzy logic. Using published map of the potential vegetation for we decipher boundary main units shown, reflecting modern climatic temperature and precipitation this region. Fuzzy logic these values on GIS platform then derived computational vegetation. Comparing it with original shows gener...

Geospatial data has become an integral part of many decision making processes specially related to socio-economic development. The geospatial information are often stored, maintained and processed by various diverse organizations in proprietary GIS systems. With increasing use in Internet and web services on line data sharing and accession has increased. Thus the major bottlenecks of integratin...

To effectively monitor the atmospheric quality of small-scale areas, it is necessary to optimize the locations of the monitoring sites. This study combined geographic parameters extraction by GIS with fuzzy matter-element analysis. Geographic coordinates were extracted by GIS and transformed into rectangular coordinates. These coordinates were input into the Gaussian plume model to calculate th...

Thematic maps of spatial data are constructed by using standard thematic classification methods that do not allow management the uncertainty and, consequently, evaluation reliability resulting map. We propose a novel fuzzy-based method applied to construct in Geographical Information Systems. An initial fuzzy partition domain features dataset is triangular numbers; our finds an optimal evaluati...
