Unlike with a paper map, where typically you just see the outline of a city or town and its streets, a GIS map can combine many layers of information such as wetlands areas, pavement type and zoning. GIS can be used to perform complex geographic data analysis including modeling and forecasting, as well as more standard type operations such as object locations. Other functions enable information to be linked or 'layered' into a model for a specific purpose. Many departments can utilize GIS information to more accurately and effectively do analysis and forecasting. The Police Department can use GIS modeling to analyze crime patterns, map crime scenes or determine trends. The Fire Department can use the GIS system to maximize coverage and response times or track hydrant locations. The Public Works Department makes use of the GIS system for salt and sand truck routes, tracking road characteristics or sewer information. The Community Development Department utilizes GIS for high quality map production work and town planning. GIS allows you to select specifications of information pertaining to your particular project and layer them to create a customized depiction according to what goal you are trying to achieve. Much of the work that the Town's departments perform depends upon timely and accurate geographic information about the Town. Therefore, it is important for Town employees to have access to information that is pertinent to the responsibilities of their position. If you would like to purchase maps or data, click here.
