Geographic Information System (GIS) is a powerful tool for capturing, storing, editing, updating, retrieving, analyzing, modeling, and displaying data that are spatially referenced to the earth.


GIS is made up of the following components: computer hardware, GIS software, databases, procedures and, most importantly, skilled personnel.

GIS Components

GIS integrates data from various different sources and helps to visualize patterns and trends that spreadsheets alone won't portray. GIS allows us to see patterns, linkages and trends that put the big picture in context. GIS allows us to manage places such as watersheds, neighborhoods, communities, and ecosystems.

GIS Layers

Global Positioning System (GPS) is a powerful tool for capturing data that are spatially referenced to the earth. This tool allows us to capture locations of City facilities and assets in a digital format in the field an to easily download to our GIS as a data layer.

GPS is a worldwide navigation system formed from a constellation of 24 satellites and their GPS receivers on the earth. GPS works through the triangulation method that measures distance by time travel of radio signals from the satellites to the GPS receiver.
