GIS / Mapping Services
L.I. Smith & Associates, Inc. began acquiring experience in GPS surveying in the late 1980's, began working with GIS software in 2000, and quickly began combining the two technologies thereafter.
We are currently using ArcGIS to manage multiple projects where survey data is overlaid with project specific geospatial data. We migrate GPS data as needed between a variety of database formats including GIS software formats, and CAD formats.
L.I. Smith & Associates, Inc. has produced a multitude of project deliverable files which provide for each structure located, the unique ID, the X, Y, & Z coordinates, and any comments for that structure. We provide deliverable files to clients in multiple formats such as ArcGIS shapefiles / geodatabase format, Excel XLS, and numerous other database formats.

Taxiway Survey and Establishment of PAC/SACS for FAA AGIS Program
Pikeville / Pike County Airport, Pikeville, Kentucky
L.I. Smith & Associates, Inc. provided a location survey as a subconsultant to Stantec, Inc. at the Pike County Airport. Survey services were required for this project in order to comply with the FAA E-GIS mapping program.
L.I. Smith set and established one (1) Primary Airport Control Station (PACS) and two (2) Secondary Airport Control Stations (SACS) monuments on the airfield in accordance with AC 150/5300-16A. Geodetic control used to establish the PACS included one (1) NGS CORS station and a B order HARN station. The SACS was established using the PACS and two (2) 2nd-order vertical benchmarks. The two (2) SACS positions were tied horizontally and vertically to the PACS. Additional survey requirements for this project included the location of a new taxiway, runway safety area and runway ends.
All data processing was completed using the latest version of PAGE-NT, ADJUST and UTILITIES, GEOID, and WINDESC available from the NGS website. Station location sketches and visibility diagrams including photography of each control point were created as documentation to meet the requirements of the FAA.
Small Diameter Sanitary Sewer Cleaning and Inspection
San Antonio Water System, San Antonio, Texas
L.I. Smith & Associates, Inc. provided GPS mapping services as a sub consultant to Quality Pipe Services for the San Antonio Water System on a project to clean, internally inspect, and record the condition of designated wastewater collection system manholes, structures, and pipelines in San Antonio.
CCTV inspection was performed using a CUES Generation 3 CCTV camera system with survey data being collected and coded per NASSCO PACP standards via WinCan Vs 8 software. The survey team at L.I. Smith & Associates provided GPS mapping services using GPS RTK methods and technology and included collecting x, y, and z coordinates on over 4,200 sanitary sewer structures and manholes.
The data collected was used to update the San Antonio Water System's GIS system.
Sanitary Sewer Inventory and GIS Mapping
City of Boynton Beach, Florida
L.I. Smith & Associates, Inc. provided services as a sub-consultant to AUI, LLC to locate sanitary sewer manholes using survey grade GPS equipment and methods for the mapping of approximately 5,000 sanitary sewer manholes and to provide assistance with GIS mapping applications. The GPS location of manholes was part of a larger project, which has a primary goal to clean, televise and prioritize rehabilitation needs for the City of Boynton Beach, Florida.
L.I. Smith & Associates, Inc. provided Quality Control by finding and locating NGS monuments in the area and comparing the located coordinates with the known coordinates to verify accuracy. Quality Assurance was practiced to ensure each point was attributed with the correct information.
Deliverable files were provided in the ArcGIS shapefile format and other database formats with the unique point ID, X, Y & Z coordinates, and other attribute information requested. The data could then be combined with attributes collected by AUI and incorporated into a GIS map for the City Utility Department. The overall project included the cleaning and CCTV inspection of approx. 500,000 feet of sanitary sewer, 1500 manhole inspections, and 5,000 GPS locations.
City of Bowling Green, Kentucky
Stormwater Mapping Project
L.I. Smith & Associates, Inc. was contracted by the City of Bowling Green, Kentucky to utilize GPS methods in locating 3500 storm sewer structures throughout the city. The project required that structures be located to within 4 centimeters in the X, Y, & Z direction. Field survey crews collected various attributes, including structure type and size. The collected attributes were formatted to work with the existing structures in the city's GIS system. Upon project completion, the data was imported into the Bowling Green's GIS system.
L.I. Smith & Associates, Inc. also added to the City of Bowling Green's Stormwater geodatabase, through GPS location, approximately 800 stormwater structures and field location, a collection of approx 1400 stormwater pipes. Data collection for both the GPS points and pipes included descriptive attribute information as specified by the client.
Cadastral Mapping and GIS for the Rowan County
Property Valuation Assessor Office, Rowan County, Kentucky
L.I. Smith & Associates, Inc. has been providing GIS and Cadastral Mapping Services as a consultant to Rowan County, Kentucky for over a period of 9 years.
When a parcel of land is sold or there is a property split by an owner, or a new subdivision is being created by an engineer or developer, the parcel information is provided to the County Property Valuation Assessor’s Office (PVA). L.I. Smith & Associates has acted as a consultant to the Rowan County Kentucky PVA office and provided Tax Map maintenance and assistance with establishing and maintaining GIS parcel layers. Work for this project has included digitizing paper tax maps, creating and updating parcels based on deeds, plats, digital imagery, and other spatial data. Services provided have also included field verification of parcels, and updating parcel information.
L.I. Smith & Associates developed the original GIS Tax Maps for Rowan County along with 12 other Kentucky counties. Custom software was developed by L.I. Smith & Associates that is still being used by Rowan County and about 29 other Kentucky counties. The software program was sold by L.I. Smith & Associates in 2011, but few modifications have been made to it by the new administrator.
The GIS data and parcel information generated by L.I. Smith was linked to the PVA property management database so that annual tax bills could be generated for property owners within the county. L.I. Smith’s service also included working directly with members of the County staff on-site in the Assessor’s Office.
