The aim of the 3D DSS project is to investigate, how an application should be built to support decision-makers in deciding, which route should be chosen to construct a new power transmission line. For this purpose, a rational solution should minimize negative impacts and offer a good alternative to any stakeholder involved. Therefore, we combine different approaches from Geographic Information Science, Multi-Criteria Decision Analysis, game theory, statistics, and communication with each other to develop a 3D Decision Support System (3D DSS) which aims at lowering the time and costs needed to plan a new power transmission line.
Key findings
-
Developed the 3D DSS – a software for planning power transmission lines at each voltage level
-
New method developed for combining overhead and underground transmission line sections
-
New method developed for identifying several Pareto optimal solutions based on one scenario
Project description
Project 1: Planning Overhead Lines with GIS
Project 2: Planning Earth Cables with GIS
Geographic Information Systems (GIS) allow calculating and visualizing power line corridors in 3D. However, existing approaches are limited to overhead lines. The goal of this project is therefore to develop an integrative approach that models overhead lines and underground cables taking into account geological, infrastructural, ecological, as well as socio-economic aspects and to integrate the algorithm into an existing 3D web-GIS-platform.
