LiDAR Application BHA
recently began testing the application for mobile LiDAR and drone
data collection for levee surveys. Surveying and subsequent
monitoring of CPRA restoration and protection projects utilizing
mobile and drone LiDAR, as opposed to aerial LiDAR and conventional
surveying, has the opportunity to provide efficiencies, accuracies
and data management not available through conventional survey methods
association and membership with the LSU’s Center for GeoInformatics
(C4G) GULFNet system allows us to provide our services efficiently,
accurately and in a relatively short time span. GULFNet is a high
precision GPS Network of Continually Operating GPS Reference Stations
(CORS) used to measure horizontal and vertical deformation across the
Gulf Coast; the network extends from east Texas across to Alabama and
up into northern Louisiana.
BHA also uses TopNET, a Real Time GNSS Reference Network delivering high accuracy positioning data to rovers.
GPS surveying is not applicable or available, BHA also provides
conventional surveying and mapping using control leveling and
traverse methods that fit the particular project scope.

Survey of physical features present underwater; measuring factors beneath the water that could affect marine activities such as dredging, marine construction, drilling, port activities, pier construction. Can be used to monitor coastline erosion, provide data for hurricane recovery programs, measure depths, compute volumes for dredging projects.
Survey of land before a pipeline is laid to determine position, depth and length; includes preliminary survey, right-of-way acquisition survey, construction staking and final as-builts.
Survey of all visible features and contours of a property and apparent rights-of-way. As well as above ground features such as buildings, trees, fences, sidewalks, manholes, driveways, utility poles, above ground utilities, etc.
