Background of Middletown’s GIS

The Town of Middletown began implementing its Geographic Information System in 2003.  In 2004 the Town was awarded a Federal Homeland Security Grant to conduct a Town-wide Aerial Base Mapping Project.  The information that was developed included the following data layers: building footprints, roads, parking areas, sidewalks, hydrography, infrastructure, railroad lines and 2-foot contours.  High-resolution large-scale color aerial photography was also prepared and provides a solid and useful foundation for the GIS.  New permanent control points were also placed enabling surveyors to tie into these highly-accurate monuments.

In 2006 a digital Parcels Base was developed that depicted the information shown on the hard copy Tax Assessor maps.  In Fall 2007 the Town contracted to digitally map and inspect the Town’s 80-mile sewer system and storm water outfalls.  Additional information such as canvassing districts, fire hydrants, open space, and zoning have been developed in-house by Town personnel.  Other geospatial data has been provided by the Rhode Island Geographic Information System (RIGIS).

Building and maintaining the Town’s GIS is an on-going process.  The Department of Planning and Economic Development is responsible for the implementation of the GIS throughout many of the Town’s Departments. The Town’s GIS utilizes ESRI’s ArcGIS technology.
