The Standardized Precipitation Index (SPI) has become a popular measure of drought across the globe. In this study, Standardized Precipitation Index (SPI) was used in annual period of time to survey on drought. Also, in order to zonation frequency of drought, geographic information system (GIS) software and Kriging method used for extracting dry areas. The zoning maps show most severe drought i...

This paper presents a new design for a census-based binational geographic information system. GIS has had limited application intra-censally i.e. between nations. The reasons are the formidable obstacles of standardization of attributes, matching of meaning of attributes, consistency of data-bases, and consistency of boundary files. Many problems in public administration can be solved by using ...

fuzzylogic computes a multi-criteria evaluation by means of either a boolean analysis, weightedlinear combination (wlc) and ordered weighted averaging (owa) of factor images. owa works withstandardized factor images and employs a variant of the wlc. it takes into account the risk associated withthe decision and degree of tradeoff associated with the variables in the analysis. in this research, ...

The key cha...

Geographical Information Systems (GIS) have long bridged the gap between geo-information databases and applications. Although conceptual modelling approaches for GIS have been particularly successful in the representation of the specific properties of geographical information, there is still a need for a better integration of user intentions and usage. This paper introduces a conceptual framewo...

The problem of the distribution of dairy products, which is classified as a combinatorial optimization problem, cannot be solved in polynomial time. In this paper, an algorithm based on Ant Colony Hybrid meta-heuristic system and Geographic Information System (GIS) was used to find a near-optimal solution to this problem. Using the former method, the nearest neighbor heuristic algorithm was use...

Geo-collaboration appears when individuals or groups of individuals work together to solve spatial decision-making problems facilitated by geospatial information technologies. In this paper we focus on current developments in geo-collaboration where we take an example of public participatory geoinformation systems (PP GIS). This research field focuses on the issues related to the participation ...
