PESI now offers GIS services.  GIS is a collection of computer hardware, software, and geographic data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.  GIS links information to location data, such as addresses, buildings to parcels, or streets within a network.  The information can be layered to give you a better understanding of how it all works together.  Layers can be combined based on the questions that you need to answer.  Our program can map your system to replace those old hand drawn maps.  We can locate your water & wastewater facilities, which allow you to make accurate changes to your maps as your system grows or is updated.  Aerial photography is also available for your system.  What is GIS?
