Lidar Services

services-lidar.jpg

GSC has over 15 years direct experience using lidar topographic/bathymetric data to address coastal issues. This includes creation of custom Digital Elevation Models, development of breaklines and integrating additional remote sensing data with field collected data in a CAD/GIS environment. The ability to incorporate remote sensing data with traditional field data provides a cost-effective option to increase the breadth of findings while limiting resource intensive tasks.

Some of our services include:

  • Custom Lidar Processing – bare earth and custom classification of mass point clouds
  • Lidar QA/QC – third party review of data quality and accuracy
  • Development of custom DEMs for user-defined modeling or analysis
  • Lidar collection planning and statement of work generation

Military Installation Resilience Review – Beaufort County, SC

Geoscience worked with Sherwood Design Engineers to provide a host of flooding risk information, including pluvial (rain), shallow coastal, and tropical storms.

Bluff Stability Analysis Using 15 Years of Lidar Data

Geoscience Consultants, LLC (Geoscience) was contracted by McSweeney Engineers to examine some of the historical and physical changes to the bluff shoreline at Magnolia Plantation along the Ashley River. To help answer these questions Geoscience leveraged about 15 years (2006/7-2020) of lidar data to assess elevation trends along the bluff shoreline in concert with the lithology and morphology of the bluff.

Marsh Evolution and Sedimentation on the Whale Branch Portion of Port Royal Sound

The Phase I project used a small marsh island on the Whale Branch creek to model processes that control marsh health and evolution in the larger Broad River/Port Royal Sound habitats.

Sea Level Rise and Infrastructure Vulnerability - Beaufort SC
Sea Level Rise and Infrastructure Vulnerability - Beaufort SC

This project focused on identifying the potential infrastructure problems that will exist as sea level rise (SLR) occurs and determining how those effects can be minimized or mitigated to ensure that the needs of both the local communities and the military facilities are accommodated. This is particularly significant in the Beaufort area due to the fact that water and sewer services are provided to the military facilities by the same regional provider that serves the local communities; and local roads, highways and bridges provide the only access to MCAS Beaufort and MCRD Parris Island.
Marsh Migration - Technical Consulting

Geoscience performed a technical review of marsh migration models, the fundamental data sets and various parameters that drive model outputs.
Shoreline Analysis and Conceptual Design

Geoscience Consultants was hired to assess the historic shoreline trends and define the various sediment transport mechanisms at a hot-spot along South Padre Island. Based on the analysis, a low profile groin conceptual design using geo-textiles was also developed.
Graveline Bayou, MS - Analysis of Marsh Elevations and Habitat Restoration Needs

To assess habitat restoration needs Geoscience Consultants was hired to examine marsh substrate elevation differences caused by the existence of a causeway running across the bayou. The reduced flow inland of the causeway may have limited natural accretion thus limiting the ability of the marsh substrate to maintain equilibrium with the optimum growth conditions.
Plymouth Park, Charleston - Breakwater Analysis

Geoscience reviewed the potential effects from a proposed offshore sill/breakwater at a boat launch for a local engineering firm in Charleston SC

Daniel Island – Alternate Shoreline Protection Schemes

Geoscience worked with a local Charleston, SC engineering firm to perform a review of past shoreline/littoral changes and assess potential living shoreline stabilization techniques for a waterfront park
