Storing and finding this information can be a large problem. GIS consists of layers of information over an accurate base map. One layer might include the road system, another drainage, and a third signage. Data from other systems, such as RSMS and SIMS, can add information to the GIS base map. All information is digitally stored in one place.
Information retrieval is quick and easy.
The system is easy to update and keep current. Selected areas can be printed to provide maps and visual information to managers, crews, and the public. Information, such as construction plans, sketches, pictures, and AutoCAD drawings can be scanned and linked to the base map. A road layer can be viewed with other layers such as water, sewer, and parcels, to show features that may conflict or prove advantageous for expansion. Municipalities can establish a GIS in annual increments.
