Water Model

Model Graphs


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.



Historical Aerial Imagery
 Project Lead:  Status: 80% Completed

1973                                                                  1988

The Moore County GIS department, along with the Tax Department, has undertaken a project to scan and georeference historical aerial photography from 1939, 1950, 1966, 1973, 1983, and 1988.  The photos are on mylar sheets that will be scanned to digital format, then brought into GIS software and placed in their proper geographic location through georeferencing.  The result will be seamless historical imagery of the county that will be a valuable asset to other county departments and to anyone interested in the way that Moore County has changed and grown over the years.


Utilities - Asset Collection Project
Project Lead: Chris Butts Status: 40 % Completed




Sewer Network






















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.

Utilities - Record Management Application
Project Lead: Chris Butts Status: 90 % Completed

Utilities Application

The goal of the project is to develop and maintain an enterprise utility record management solution linked to the county's utility GIS infrastructure. This will be a web based application designed to create and maintain work orders and inspection records, and make this information available to the Public Works department in user friendly reports. This application will manage the collection and storage of inspection results, along with processes that will enhance document management by centralizing the storage of any materials related to an inspection, such as pictures, notes, CAD files, etc.


Address Field Verification
Project Lead: Rachel Wall Status: 85 % Completed

Address Field Verification

As additional Moore County government offices and municipalities begin to rely on the Moore County GIS Department for information and analysis it is important for the data collected, created, and maintained by the Moore County GIS Department to be as complete and accurate as possible.  With the additional responsibility of addressing in the county it has become even more important that the GIS department have an accurate address database.


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.


Mobile GIS-Field Laptops

The GIS department has worked with both the Tax Assessors and Zoning Enforcement officers to assess and develop solutions for their mobile GIS requirements. This involved putting in place a cost-effective, easy to use GPS solution that met the needs of workers in the field. The department also developed custom tools, data sets, and data update procedures to insure that workers in the field were able to perform their jobs efficiently and to create a seamless integration with the county's GIS data.


Historical City Annexations Records





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.


Master Street Address Guide - MSAG

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.
By bringing several layers into topological agreement, a much simpler ESN network was achieved. The next step was an overhaul of the MSAG table maintenance process. The goal was to have the MSAG related directly to the “live” street center line data. This involved the entire GIS department working to populate the street centerline layer with the appropriate ESN number. After the centerlines had the appropriate information attached, a process was created in ArcCatalog that generates a dynamic MSAG table for the county at the push of a button.



2007 Aerial Photography Update



Comparison of 2003 Imagery to 2007 Imagery

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.
