“…We can imagine the contact between GIS and spatial data analysis as a spatial data matrix where, at a conceptual level, it consists of rows and columns where rows refer to cases and columns refer to the attributes measured at each of the cases, and the last columns provide the spatial referencing.

“…GIS has made possible the conceptualization and representation of geographic reality in finite digital forms, that is, as countable numbers of points, lines and areas in two-dimensional space. [5] Spatial data analysis is concerned with this domain where the geographical referencing of objects contains important information. We can imagine the contact between GIS and spatial data analysis as a spatial data matrix where, at a conceptual level, it consists of rows and columns where rows refer to cases and columns refer to the attributes measured at each of the cases, and the last columns provide the spatial referencing.…”

Geographic Information Systems are computerbased tools for mapping and analyzing spatial data. The technology dates back to 1960 [1]. In many spatial data applications, the events at one location are highly influenced by the events at neighboring locations which is known as spatial dependence [2]. This spatial dependence is measured by spatial autocorrelation which could be viewed as property of a variable that is distributed over space [3].As part of the economics discipline GIS technology has been used to automate the marketing of the real-estate industry. It is helpful for finding properties by analyzing data around locations, demographics, aerial photographs and traffic counts [4]. In this case, spatial data could be visualized in different formats. One of these formats is the map. When used in real-estate industry, GIS simplifies urban and resource planning and management due to its features of storing, retrieving and mapping large areas with huge volumes of spatial data.There are several approaches to explore and search for realestates in Lebanon, but these approaches have many limitations; to begin with, they are neither map-enabled nor GIS-integrated and hence do not provide graphical representations of estates, second, they do not cover the services related to distance and altitude calculation of geographical areas, moreover, the modeling of traffic information, population and absorption rates in addition to road mapping facilities are also absent. To surpass some of the above limitations, we propose UGIS which is a solution to model the real-estates search services in Lebanon. UGIS is enhanced with Geographical Information System. Although ZipCode addressing schemes are not yet used in most of the middleeastern countries, the GIS technology when present, makes the search service easier, faster and more accurate due to the mapping facilities used in our solution.UGIS, or "You Get It Simply", was developed to search and explore the different types of real-estates and properties around Lebanon. The absence of such solutions in this country, gives UGIS an added value, since it uses a GIS to provide a graphical representation of geographical locations of the capital which will allow the users to get an idea of the look and the surrounding of the estates; this is achieved by displaying the region of where the estate is located in addition to other related details over two different types of maps: Cadastral map and a Road map.

“…Effective deployment of GIS in power distribution would go long way in the power industry efficient and financially viable besides enhancing the consumer's satisfaction due to uninterrupted quality power supply [10]. GIS today represents a solid basis for spatial data analysis [11]. The spatial analysis tools available in the GIS have been used in various planning studies of the electricity distribution network around the world [12], [13], [14], [15].…”

Electric energy has become essential nowadays not only for the daily life of each of us but also for the economy of different countries. The dissemination of geographic information plays an important role in national development as it facilitates communication between managers, investors, and consumers in this sector. Since the management of electricity network data was previously done in Tunisia based on paper maps and plans, the purpose of this article is to present a case of planning based on GIS, Web, and 3D Web GIS, which would have significant positive consequences on this sector from a technical and financial sides with an improvement in customer satisfaction and the creation of an intelligent electricity network which will be a real decision-making tool. This work draws up an inventory of the network MV (Medium Voltage)/LV (Low Voltage) of the region of Medjez El Bab which routes electricity to the big centers of consumption with access to MV/LV subscribers. The analysis of the network's impedance allowed carrying out different scenarios to optimize performance and obtain more realistic routes. Many thematic maps were produced as part of this project (Slope map, Land use map, map of the MV voltage domains, map of the MV/LV transformer stations power, etc.). A three-dimensional virtual city has been developed to visualize the graphical and attribute data for the study area. A Web and 3D Web GIS applications that allows the publication of the interactive maps on the Web as well as the database information have been developed to offer users the possibility of consulting the produced products by internet. Finally, a website related to the study was developed.
