Geographic Information Systems (GIS)
A GIS, or Geographic Information System, is a computer-based software system for capturing, storing, checking, integrating, manipulating, analyzing, and displaying data related to positions on the Earth's surface.
Through the capabilites of GIS, GAI is able to provide services relating to GPS control networks and surveys, GIS surveys, data management, digital file conversions, aerial mapping control, and quality assurance testing.
Whether siting a wind farm location or finding the best route for a transmission line, most of our problems have a geographical component. GIS gives us the power to create maps, integrate information, visualize scenarios, solve complicated problems, present powerful ideas, and develop effective solutions. GIS thus becomes a support tool that combines the attribute data handling capabilities of a relational database system with the spatial data handling capabilities of CAD and desktop mapping systems. Gresham and Associates, Inc. provides GIS services to both the private and public sectors.
Want GIS implemented for your town? Gresham and Associates, Inc. provides the in-house capability of locating and managing all public works assets. As geo-spatial professionals, our organization strives to strengthen your city’s infrastructure for better asset management, planning, and prioritization. We accomplish this in two stages (Please see below).
We accomplish this in two stages:
Locating involves survey grade geographical location of many civil assets such as transportation and water infrastructure, fleets of vehicles, signs, and trees, to name a few. This is achieved by such methods as aerial photography and on-site locating using GPS.
Once location data is compiled, we then work towards the construction of these materials into a database. This database will enable us to quickly retrieve geo-referenced infrastructure information that includes detailed information about easements, utility operators, even ownership information of land parcels.
This process will allow us to make public works planning more efficient and accurate.
