At the request of the Public Works Department, the Moore County GIS Department is building a hydraulic water distribution model. This will help in determining how future growth will affect the existing water system, as well as future expansion. The water distribution model will also help in making the best decisions on locating critical areas for improvement in the existing water system, by looking at various fire flow, water quality, and capital asset management simulations.
The goal of this project is to create a complete water and sewer system network in the county’s enterprise GIS. Working in conjunction with the Moore County Public Works Department, GPS is being used to field verify and collect all existing utility data. In addition, the GIS Department is collecting sewer manholes with a survey grade accuracy GPS unit. The higher accuracy GPS unit collects a more precise position, and allows a rim elevation to be collected for the manholes. With the rim elevation being collected, it will allow the sewer system to be modeled so the best decisions are made with future developments. In addition to utility asset collection in the field, the GIS Department is also recording all of the information from engineering record drawings and putting it into the GIS system. The record drawings are also being scanned, so that digital copies of the drawings serve as a back up to the original paper copies. Other goals for this project are to assist in data management, development of workflow processes, and to work with municipalities in the county on the collection of their utility systems. The Public Works Department will benefit from this complete system through more efficient response times, preventative maintenance, and the ability to better plan for future projects.
Therefore the Moore County GIS Department with the aid of the municipalities began a process of field verifying addresses. This process has been accomplished by first targeting areas where there were no known addresses and or where there were problems with current addresses being used. Then using a tablet PC with GIS software and the necessary data loaded on the laptop, the GIS department and a representative from the corresponding municipality were able to go to the areas of interest to collect addressing information. A small GPS device that plugged into the tablet PC also aided the collection of data by verifying the exact locations of the addresses.
Develop and maintain digital annexation records for all eleven municipalities in Moore County . This was achieved by relating annexation documents to a polygon layer in the GIS system. Using the original annexation documents as a guide, each municipality was divided up based on the legal description of each annexation. The next step was to extract effective date, annexation number, title, deed book, deed, and page number and store these in the attribute table. Finally each annexation document was scanned to a PDF.
GIS plays a vital role in Emergency Service Response. It is essential that the correct responder is sent at the time of an accident. The Moore County GIS Department, at the request of the Public Safety department, undertook a project to revise the emergency service response areas and streamline MSAG table maintenance. This project involved the coordination of 17 fire departments, 10 rescue units, and several county departments. At the time of the projects inception there were 456 ESN polygons in the county. The large number of ESN's complicated maintenance of the layer, and caused confusion in dispatching the correct responders. The ultimate goal would be a seamless integration the streets, addressing, ESN, and MSAG tables. The first step was a revision on the existing public safety layers.
Sample of 2007 Image Same Area Photographed in 2003
Moore County has contracted an update of county-wide digital orthophotography ("leaf-off"). The resulting imagery is used to update key infrastructure data layers (roads, buildings, etc.) and compare changes in landcover (trees, water, etc.). The 2007 imagery acquisition process will take advantage of the latest digital imaging technologies such as inertial measurement and airborne GPS to ensure spatial accuracy. The updated imagery will also include color (RGB) and near-infrared (NiR) from one source.
