Water Pipeline Route Optimization Using GIS and Multi-Criteria Analysis

A paper by Francisco Eudes do Amaral discusses a GIS-based optimization model for water pipeline alignment. The model uses cost variables and criteria like slope, altitude, distance to rivers, and proximity to highways to simulate minimum-cost routes. The study area is an excerpt from the Pajeú pipeline in Pernambuco, Brazil, using data from the Pernambuco Three-dimensional Program and SRTM/TOPODATA.
