(Oak Island, N.C.) Mark A. Smith, CEO of Geospatial Holdings, Inc. (OTCBB: GSPH), a developer and producer of technologies and services for identifying and managing underground pipeline assets, has written an article published in the April issue of Water & Wastes Digest magazine. In the article, titled “3D Mapping and GIS: Key Tools for Utility Line Maintenance,” Mr. Smith highlights the use of Geospatial’s Smart Probe™ technology to help complete a project involving the mapping of water and sewer lines undertaken by the Town of Oak Island, North Carolina.

Geospatial was contracted to perform the project in September 2009. The first of two phases entailed the forensic mapping of an existing 1,500-foot long, 12-inch diameter water line located in the Atlantic Intracoastal Waterway, which connects Oak Island to the mainland. This line was mapped in order to determine the location of an area damaged during a previous pipeline installation. The second phase of the project performed by Geospatial involved the mapping of a newly installed 900-foot long, 12-inch diameter force main sewer pipeline under the Davis Canal, located between the Atlantic Ocean and the Waterway. This job was done in order to avoid conflicts with other pipelines in the vicinity of the island as the sewer project progresses.

In the article, Mr. Smith writes: “Geospatial engineers first fused a 4-inch diameter high-density polyethylene (HDPE) liner on-site. This was then pushed through the 1,500-foot water line to the damaged area. A Smart Probe™ was then sent through the line and successfully derived an accurate set of x, y, z coordinates that will assist when the necessary repairs are made. In the second phase, once again the Smart Probe™ was used, this time to map the position of the 900-foot long sewer line. The Probe’s readings indicated that this line may have been installed as much as 15 to 20 feet above its intended position…. In both phases of the project, Geospatial provided the town with a plan and profile report, accurate as-built drawings, and positional data for the pipelines that can be integrated into GIS or AutoCAD.”

The Smart Probe™ is a proprietary, autonomous pipeline mapping system that is capable of mapping the world beneath our feet in 3D and at a fraction of the cost of conventional techniques. The Smart Probe™ accurately determines the location of any and all utility pipes with internal diameters ranging from 1.5 to 60 inches. It travels through a pipeline at up to six feet per second; as it does so, it records 800 angular and linear velocity changes per second along the x, y and z axes. The data acquired by the probe can be stored on a laptop PC or immediately viewed and evaluated in the field. Alternatively, the data can be transferred via the Internet for evaluation, or stored and entered into a GIS/CAD database for future reference.
