Pipeline Route Layout and Analysis Using mPathtm - (An integrated GIS/Access Data Base Evaluation Tool)

Pipeline route evaluations can be quite a challenging and frustrating process. The purpose is to select the most appropriate alignment for the given pipeline. This alignment can be through varied land uses, environmental features, and jurisdictional areas all having specific requirements and needs. The challenge is to adequately define the potential impacts for each alignment in a quantified and justifiable manner that is easy to use, yet allows the method to be adjusted to the local area.
