A Geographical Information System (GIS) utility, such as network analysis is a tool used to solve common network problem, This study is intended to use GIS as a tool of analyzing. integrating and displaying information. the overall activities of the work were concentrated around sub area selected as the study site in the Khartoum north city (Khartoum ) of main capital, Sudan .To demonstrate the use of road network analysis, this project focused on determining the best route between too destinations , the closest facility from a given incident , and a service area for a given facility . The present study attempt to analyze the potential use of network analysis in defining the optimal service area of different services such as hospitals, schools and university of Khartoum north. Generally for the purposes of this project ,distance is taken as impedance in order to find the best route and the closest facility and that of travel time is taken as impedance in order to find the service area.

Tourist Resource

In inland areas water is an important resource for attracting tourists as is the case in Extremadura. For this reason this research aims to determine its attraction capacity for travelers from other parts of Spain. In 2017, 13,848 surveys were carried out in the tourist offices of the region, from which 3403 were selected from those practicing tourism related to water. This has allowed us to find out the type of tourist who visits the area and his/her origin. By means of a geographical information system, a network analysis was applied to determine the attraction capacity of certain infrastructures. This result confirms that the most frequently visited areas coincide with the presence of natural swimming pools, although reservoirs do not act as centers of attraction for tourists although they do for visitors. At the same time, it was found that tourists practicing activities related to water resources come from neighboring areas but their attraction capacity extends to distant areas which coincide with areas that were the destination for regional emigration. Moreover, we advocate the need for establishing tourist policies involving greater tourist exploitation of reservoirs and the deseasonalization of tourism in the northern area, where most areas prepared for bathing are to be found.

Hierarchy Process

The aim of this study is to analyse the potential of geographical information system (GIS) in decision making in rail route planning process. The various parameters affecting the alignment of rail route are considered in this study and a feasibility map is prepared considering the cumulative effect of these factors. The factors considered in this study are road network, slope, topographical characteristics and drainage characteristics of study area. Each parameter is given weights according to analytic hierarchy process (AHP) in GIS environment. The layers of parameters affecting the feasibility of route are overlaid in GIS environment to find a feasibility map. Feasibility map is divided into five categories i.e. very low, low, moderate, high and extremely feasible on the basis of feasibility index.

Maximum Value

In this paper we show how it can be useful to the probability of intersections in the determination of a classification rule for raster conversions in Geographical Information System (GIS) and GRASS GIS for the Road Network Analysis (RNA). We use a geometric probabilities approach for irregular path considering these results for transportation planning operations. We study two particular problems with irregular tessellations, in order to have a situation more realistic respect to map GIS and considering also the maximum value of probability to narrow the range of possible probability values.
