TRMUA's Geographic Information System (GIS) began in 2005, in an effort to assemble 40 years of paper plans and files into a centralized mapping interface.The system was built entirely by in-house staff, without the use of any outside consultants, and was completed within two years.
All 9,600 of the MUA's Sewer Manholes had their exact (x/y) coordinates verified in the field using sub-meter GPS units. Over 600,000 Line & Manhole attributes where entered into a centralized database from over 3,000 Engineering plans. In addition, an entire GIS Parcel base map was created, from scratch, to include additional elements not typically found on the Tax Maps, namely 3,000 Individual Condo Units and all Major Apartment buildings were added to the base map, which was then aligned to NJ State / USGS Orthophotography. The system is now available for all MUA office staff across an internal network, and to all field staff via 'ruggedized' laptop units. The system has increased operational efficiencies across all departments, by allowing instantaneous access to data that previously had to be searched for amongst reams of paper files and plans.The system also allows our field crews access to all the information they need to quickly assess and properly address emergency situations.
The system has grown beyond MUA's sewer infrastructure and now includes the following data layers:
-Parcels linked to the Tax Assessor's database -Water consumption data from United & American Water Companies -NJ DOT Street Layer -FEMA 100/500 Year Floodplains -NWI Wetlands -USDA Soil Polygons -Public & Private Fire Hydrants - Toms River Township Ward & Zoning Layers - USGS Quad Sheets with Hillshade Relief - Multiple Aerial Imagery sets from various years - Zoning & Ward Maps - Toms River Business Improvement District Maps - Microsoft Streets Basemap - Links to Microsoft Bing Bird's Eye Imagery for each Property - NGS Survery Markers - 2010 Census Data Mapping
- 2011 USGS 1/9th Arc Second National Elevation Data (NED)
- 2012 Hurricane Sandy / NOAA / FEMA Layers
- 2014 FEMA Pre-FIRM Maps for Ocean County
