Introduction

L.T. Mapping Services, Inc. specializes in providing both the telecommunications and energy industries with complete, accurate and up-to-date mapping and surveying procedures. We utilize the latest in advanced computer technology and both GPS and conventional survey for cross-country telecommunications, gas-gathering facilities, and cross-country pipelines.

L.T. Mapping Services, Inc. has the capabilities of providing our clients with a complete package for construction bid. Services include complete mapping and survey facilities for:

• Cross-Country and Metro Telecommunications
• Gas Gathering
• Cross-Country Pipelines
• Cellular Tower Sites
• GIS Mapping
• Inventory Survey and Mapping

Other services include:

• As-built Services based upon inspector's reports and other reports generated by the Client.
• Route Selection
• Right-of-way Acquisitions

L.T. Mapping Service's is a company of Excellence and Integrity. We take great pride in completing projects within client's budget and time frame and in furnishing clients with service that is above and beyond their expectations.

The company is directed by Mr. Larry M. Tucker, who has over 25 years experience in the mapping industry. He has personally managed projects ranging from 5 to 500 miles in length and encompassing all geographic regions of the United States. With his extensive knowledge he can not only effectively deal with problems as they arise but can also anticipate problems, thus saving clients both time and money.

Company Synopsis

It is L.T. Mapping Services, Inc.'s intention to stay at the leading edge of new survey and mapping technology and practices in order to provide an accurate and cost effective product for our clients.

Survey

• Our GPS receivers have the capability of receiving data from a total of 24 satellites, both U.S. and Russian, thus reducing down time in the field due to the lack of available satellite lock. This coverage also enhances our use of GPS equipment due to canopy overhang and building obstructions.
• Omnistar 7000 Receivers allow for real-time correction, which eliminates the need for post-processing of data. These are submeter systems (normal field test for accuracy 1 foot or less, X and Y coordinates) and do not require bases stations.
• Data collection is achieved by Fujitsu ST 1200 pen computer with 2 GB of storage utilizing Pen Map software. This allows the GPS technician complete information to satellite availability, which insures every shot is accurate. All line work is produced in the field and all nodes are tied to a code list and specific line type, all of which can be customized to the clients needs.
• In areas where GPS surveying is not the ideal method, we use total stations with Pen Map software or HP 48 collectors using TDS or SMI collection software. When using total station equipment as the primary source, intermediate control points are set by GPS for geo-referencing of data. All surveys accomplished by L.T. Mapping Services, Inc. are geo-referenced to the coordinate system preferred by our clients.

Mapping

In conjunction with our survey practices, we also use the latest mapping software available. We currently use AutoCAD 2004 software, along with AutoCAD Land Development Desktop. We have tailored our mapping process to be flexible for telecommunications, pipelines and gathering systems.

In addition to streamlining the flow from survey data to mapping data, we now offer automated alignment sheet generation.

• After importing of survey data begins development of the base drawing. We can also implement electronic third-party base maps, if desired by client. (i.e., aerial photography, etc.)
• After completion of the base map and the alignment or location of the proposed cable or pipeline has been established, the automatic generation of survey stations and offsets are calculated.
• Finally, automated alignment sheets are generated, complete with survey stations, either horizontal or sloped, match lines, materials and ground profile.
• An Access database is generated, reflecting X, Y and Z coordinate values, station numbers and offsets to surveyed points and items crossing the alignment. The database also contains a description of all items. This database can be exported to Excel, Word or DBF for client use and can export directly into Arcview GIS Systems.
• The end product is a computer-generated alignment sheet with very little CAD cleanup required. Elimination of equations and re-stationing can be accomplished in a matter of hours, not days.

With our process, generation of as-built drawings with corrected stations and offset can be accomplished with a reduced cost savings for our clients. We provide our clients with an automated mapping process that is cost-effective for all phases of mapping and provide GIS data as an end result.

All survey and mapping services provided by L.T. Mapping Services, Inc. will be geo-referenced to the coordinate system preferred by the client.
