GIS-Based Planning and Web/3D Web GIS Applications for the Analysis and Management of MV/LV Electrical Networks (A Case Study in Tunisia)

Abstract

Geographic Information Systems (GISs) have an essential part to play in the management and planning of electricity distribution. Since the management of electricity network data was previously conducted in Tunisia based on paper maps and plans, the purpose of this study is to present a case for the planning of an MV/LV (Medium Voltage/Low Voltage) electrical network in the region of Medjez El Bab (North-West of Tunisia), based on GIS, Web, and 3D Web GIS, to create an intelligent electricity network, which will be a decision-making tool. Analyses of vehicle transport and pedestrian accessibility between installations and a generation of Origin-Destination cost matrix to calculate the average transport distances between the service points were conducted. Moreover, an analysis of the network’s impedance allowed carrying out different scenarios to optimize performance and could obtain more efficient routes. The different analyses carried out were crucial for the maintenance of the electrical network and for future urban planning. A 3D virtual city has been developed to visualize graphical and attribute data for the study area. Web and 3D Web GIS applications that allow the publication of interactive maps on the Web as well as database information have been developed to offer users the possibility of consulting produced products by using the internet. A website related to the study was equally developed to gather the different obtained results.

Assessment of groundwater vulnerability to pollution in an Arid environment

“…3). A weight between 1 and 5 is assigned to each parameter, and each parameter is classified into several classes, each of which is associated with a rating ranging from 1 to 10 (Hamza & Chmit, 2022;Kirlas et al 2022). Unlike the DRASTIC method, the SINTACS method makes it possible to use, at the same time and in different cells, variable weights depending on the situation (Goyal et al 2021).…”

“…Each of the parameters is associated with a depth varying from 1 to 10, defined according to the intervals of the values (Goyal et al 2021). The lower depth represents conditions of lower vulnerability to contamination (Hamza & Chmit, 2022;Chakraborty et al 2022).…”

A web-based application for the spatiotemporal monitoring of the impact of nature-based solutions on the urban environment and the well-being of citizens: the euPOLIS visualization platform

“…Those computational tools make it possible to link georeferenced databases to digital maps and improve the visualization of the case's study geographical characteristics. The visualization modules frequently incorporate extra features by utilizing data from various sources 39 .…”

Measuring geospatial information system success on individual performance impact

“…This is an effective information device to deal with spatial data and complex interactions in cities and state constructions [16]. It is also important in the management and planning of technology distribution including even electricity [17]. PT Telkom has developed a geospatial-based sales information system since July 2017 with only six display layers, namely the occupancy ODP layer, the technician layer, the sales force layer, the mobi layer (mobile IndiHome), the demand layer, and the work order layer for broadband internet installations.…”
