PROJECT: Beaufort County, South Carolina (752 square miles)
LIDAR 1’ Interval Contour Mapping

PROJECT FEATURES
1’ Interval Contour Mapping
Most of County Leaf on Year Round
High Accuracy Through Canopy and Vegetation
Data Used for GIS Base Mapping and Engineering

Planning and Design
Verified Accuracy –8cm RMSE


Shaded Relief Map of Portion of Beaufort County

DESCRIPTION
In February of 2002 LMSI was sub-contracted by Thomas and Hutton Engineering Company of Savannah, Georgia to provide airborne laser mapping services for Beaufort County, South Carolina. LMSI was chosen as part of the Thomas and Hutton team because of our extensive proven expertise in providing 1’ interval contour mapping through dense canopy and vegetation in low coastal areas.

LMSI utilized an Optech ALTM 2033 33kHz laser system. We used a raw laser point spacing of sub 3’ for the project area in order to penetrate the dense canopy and to obtain maximum definition of the county’s drainage features, which are crucial in low coastal areas. Our crews arrived on site and followed our proven and tested procedures. We began our mapping operation, which included our team approach with ground control, laser data collection, GPS and laser data processing and quality review, all professionally managed in one operation. We completed all the laser data collection and laser data processing in a little over 2 weeks. We performed the final quality review of all the laser data on site, departing three weeks from the commencement of data collection. Most of the project area was covered in vegetation and canopy.

Our data was submitted to FEMA to review for compliance with FEMA guidelines for LIDAR flood hazard mapping. Their comment on our LIDAR data was that it “easily complies with the standards and guidelines of FEMA Appendix A”, and that it was a “pleasure to work with our data” and that it was “some of the best data they had seen from a high repetition system”. The data was independently ground truthed through the various vegetation and land classification types as required by FEMA, and the average RMSE for our data was around 8cm, suitable for NMAS and FEMA 1’ contour mapping.

Shaded Relief Map of Portion of Genesee County

DESCRIPTION
In March of 2002 LMSI was sub-contracted by Kucera International, Inc., of Willoughby, Ohio to provide airborne laser mapping services for Genesee County, Michigan. LMSI was chosen as part of the Kucera team because of our extensive, reliable, proven expertise in providing high accuracy LIDAR surveys.

LMSI utilized an Optech ALTM 2033 33kHz laser system. We used a raw laser point spacing of sub 3’ for the project area in order to get optimum resolution and minimize shadowing in an urban environment and also to get good definition of the county’s drainage features, which are crucial for the Countys engineering planning and design. Our crews arrived on site and followed our proven and tested procedures. We began our mapping operation, which included our team approach with ground control, laser data collection, GPS and laser data processing and quality review, all professionally managed in one operation. We completed all the laser data collection and laser data processing in about 1 ½ weeks. We completed our GPS ground truth surveys and performed the final quality review of all the laser data on site, departing two weeks from the commencement of data collection.

Sub 15 cm Required Accuracy


Ortho Photo Draped over LIDAR DTM

DESCRIPTION
In May of 2003 LMSI was sub-contracted by GRW Aerial Surveys to provide airborne laser mapping services for Marion County, Indiana. LMSI was chosen as part of the GRW team because of our extensive proven expertise in providing high accuracy LIDAR data, even through dense canopy and vegetation.

LMSI utilized an Optech ALTM 2033 33kHz laser system. We used a raw laser point spacing of sub 3’ for the project area in order to penetrate the dense canopy and to obtain maximum definition of the county’s drainage features. Our crews arrived on site and followed our proven and tested procedures. We began our mapping operation, which included our team approach with ground control, laser data collection, GPS and laser data processing and quality review, all professionally managed in one operation. We completed all the laser data collection and laser data processing in a little less than 3 weeks. We performed the final quality review of all the laser data on site, departing three weeks from the commencement of data collection. The county was in summer leaf on condition.

DESCRIPTION
In September of 2000 LMSI was contracted to provide airborne laser mapping and digital photography services for SVS-Boeing of Albuquerque, New Mexico. LMSI mapped a railroad corridor that ran from Albuquerque to El Paso along mountain valleys and through mountain passes. An Optech ALTM 2025 25kHz laser system was utilized along with a Kodak DCS 420 digital camera that was integrated with the laser system. Our crews arrived on site and followed our proven and tested procedures. We began our mapping operation, which included our team approach with ground control, laser data collection, GPS and laser data processing and quality review, all professionally managed in one operation. We completed all the laser data collection and laser data processing in 4 days, despite rugged terrain and severe wind conditions, sometimes exceeding 50 miles per hour.

Shaded LIDAR Relief Map of City of Gadsden Airport

DESCRIPTION
In April of 2000 LMSI was contracted to provide airborne laser mapping services for the City of Gadsden, Alabama. LMSI provided 2’ interval contour mapping for the City of Gadsden Airport and for a proposed golf course using an Optech ALTM 2025 25kHz laser system. Our crews arrived on site and followed our proven and tested procedures. We began our mapping operation, which included our team approach with ground control, laser data collection, GPS and laser data processing and quality review, all professionally managed in one operation. We completed all the laser data collection and laser data processing in one day, with no flight lines requiring re-flights. We completed our GPS ground truth surveys and performed the final quality review of all the laser data on site the same day, departing that afternoon. Most of the project area was covered in vegetation and forested lands.

In May of 1999, LMSI was contracted to provide airborne laser mapping for several resort development sites located near Hilton Head Island, South Carolina. The requirements were for 1’ interval contour mapping through dense coastal canopy and vegetation, already leaf on with the project being flown in late spring. The mapping data was used for the engineering planning and design of roadways, utilities, drainage, and all infrastructure improvements. We began our mapping operation, which included our team approach, with ground control, laser data collection, GPS and laser data processing and quality review, all professionally managed in one operation. We completed all the laser data collection and laser data processing in 7 days, and delivered the completed mapping in less than 90 days.
