GIS REPORT 2016 KING GEORGE COUNTY DEPARTMENT OF COMMUNITY DEVELOPMENT
Background The GIS (Geographic Information System) coordinator was hired in 2001 to develop a GIS for King George County. Prior to 2001, a permit technician maintained the E-911 addressing system (in AutoCAD) that was established by MSAG data consultants in the early 1990s. Below is a summary of milestone GIS events; In 2002, a portable GPS unit (~3 foot accuracy) was purchased to improve the location of all new buildings and driveways for addressing purposes. In 2003, 2007, 2010, and 2014 King George received aerial imagery from the State of Virginia for use in data creation and mapping. In 2004, the GIS had grown to over 30 data layers (parcels, zoning, roads, wetlands, flood zones, etc.). In 2005, King George hired MSAG Inc. to digitize the hardcopy tax maps (Commissioner of the Revenue) into the GIS, where they are currently maintained and updated on a quarterly basis. In 2005, King George hired MSAG Inc. to create/host the OnlineGIS, allowing anyone with an internet connection to use the GIS data. The OnlineGIS currently has over 3,000 users and is updated quarterly. In 2006, a GIS Analyst position was created to help with the maintenance of the GIS system. In 2007, MSAG Inc. was hired to digitize the hardcopy zoning maps into the GIS, where they are currently maintained and updated on a quarterly basis. In 2007, King George paid to have 4-ft contours derived from the 2007 aerials that we received from the State of Virginia. 2016 by the Numbers Plotted 195 maps for staff and citizens. Filled 24 GIS data requests from external organizations. Made 191 address changes to the GIS. Made 14 road changes to the GIS, including the addition of 10 new roads. 775 parcels were changed in the tax maps, using plats and coordinate geometry. The OnlineGIS averaged 3,386 unique users a month. 408,191 maps were created with the OnlineGIS. 16,767 water, sewer, and stormwater infrastructure assets were added to the GIS. Maintained and managed over 400 GIS layers. 2
2016 in Review New Land Cover dataset from DEQ/VGIN The GIS continues to provide quarterly updates of; tax maps for the Clerk of the Courts and the Commissioner of the Revenue, zoning maps for the Department of Community Development, digital updates of GIS data to the OnlineGIS, which is used by approximately 3,386 unique users a month, and digital updates to the state of Virginia, which uses our data in array of statewide data services. The GIS also provided various analysis and mapping to County departments throughout the year, including: Analyzed and mapped closest facility of soccer registrations for Parks and Recreation. Provided Comprehensive Plan mapping for Community Development showing VDOT improvements. Mapped all county owned property for County Administrator. 3
Created maps for Emergency Service grant in Fairview Beach. Mapped potential fire station sites for Fire Chief, including parking and building site design. Imported and mapped new land cover dataset from DEQ/VGIN. Developed residential address density analysis for Parks and Recreation. Created water and sewer infrastructure maps for Service Authority reporting. Provided the Sheriff Office with mapping to investigate noise complaints. Creating maps and GIS queries for the Commonwealth Attorney s office to use in court cases. Provided mapping to Economic Development for potential clients. Used fire and rescue incidents to map and analyze fire and rescue response. Updated database for the Septic Pump Out program and provided mailing labels for letters. Water and Sewer Mapping Project Residential Address Point Density map GIS work continued on the infrastructure project for the Service Authority. The water, sewer, and storm water infrastructure assets for the Courthouse service area, Oakland Park service area, Fairview Beach service area, Potomac Landing service area, and other areas were input into the GIS using GPS, CAD, aerials, and old plans. Over 16,000 infrastructure assets were brought into the GIS. Data driven map books were updated and web apps were created on ArcGIS Online to disseminate this data to County staff. 4
Future Projects 1. Continue work on water, sewer, and storm infrastructure data. 2. Develop Next Generation 9-1-1 plan for GIS. 3. Leverage ArcGIS Online, creating useful applications for County departments. 4. Look to expand services and support that the GIS provides. 5
