Drone LiDAR Surveys in Mississippi

In the Delta, the whole argument for LiDAR comes down to a few inches. The Mississippi Alluvial Plain runs from roughly 94 to 210 feet of elevation across two hundred miles, which means a rice field, a catfish pond, a duck impoundment, and a drainage ditch are all designed around relief you cannot see standing in the field. Six inches decides where the water goes. A survey that misses six inches has missed the job.

That is the specific problem drone LiDAR solves in Mississippi, and it's different from the problem it solves in hill country. Up in the Loess Hills or down in the Piney Woods, LiDAR is about seeing the ground through trees. In the Delta it is about measuring ground that is almost perfectly flat with enough density that the low spots are real, not interpolated.

What Mississippi already has, and why it isn't enough

Mississippi is better covered by public LiDAR than most Southern states. The Delta was flown in 2009–2010, and statewide collection under the USGS 3D Elevation Program ran roughly 2015–2020, distributed through MARIS as classified LAS, bare-earth DEMs, and county contours. Point spacing on those datasets runs about 1 to 4 meters, with DEMs delivered at 5-foot and 10-meter posting.

Vintages and coverage change as new collections are added. Check before you assume what exists over your tract.

That data is genuinely useful for watershed-scale hydrology, floodplain mapping, and a first look at a property. It is the wrong tool for designing a levee or leveling a field, for two reasons.

Density. Public QL2 LiDAR is nominally two points per square meter. A project-scale drone flight runs hundreds. On flat ground that is the difference between a surface that shows the general trend and one that shows the rice levee you cut last year, the relic slough, and the blown-out pipe under the turnrow.

Date. A Delta field flown in 2010, or even 2018, has been leveled, ditched, and flooded many times since. Public LiDAR tells you what the ground was. A project flight tells you what it is the week your engineer designs against it.

Where the inches matter most

Rice and row-crop land leveling. Mississippi planted about 164,000 acres of rice and 1.8 million acres of soybeans in 2025, much of it Delta ground that gets precision-leveled or furrow-irrigated on a designed slope. A dense bare-earth surface before the dirt pan moves gives the cut-fill map and the volume; the same flight after the job verifies the grade.

Catfish ponds. The state had roughly 29,900 water surface acres in catfish as of January 2025, and pond renovation is constant: reworking levees, deepening, splitting, converting to split-pond systems. Every one is an earthwork problem with a volume attached.

Private duck impoundments and flooded timber. Along the Yazoo, the Big Sunflower, Deer Creek, and the hardwood bottoms between them, the design question is always the same: what floods at what pool elevation. That is a terrain-model question, covered in detail on our levee surveys and flooded timber modeling pages. It is one flight for both.

NRCS wetland easements and EQIP practices. Wetland Reserve Easement restorations in the Delta are built on low levees, water control structures, and shallow-water areas designed to a few tenths of a foot. The engineer needs a current, dense surface to lay those out, and the as-built check afterward is the same flight again.

The public levee context, and where private work starts

The big picture in the lower Delta is federal. The USACE Vicksburg District signed the Record of Decision on the Yazoo Backwater Area Water Management Project in January 2025: a 25,000 cfs pump station, pumping to 90 feet in crop season and 93 feet otherwise, with nonstructural features and mitigation land attached. The Mississippi Levee Board is the local sponsor.

The federal levees have their own survey data and their own engineers. Where we come in is everything inside that system: the private levee around a 400-acre impoundment, the field drainage plan that has to work at a 90-foot pool, the pond complex, the pipeline right-of-way across a bottom. Public data tells you what the Corps built. A project flight tells you what your dirt is doing behind it.

Under canopy: LiDAR, not photogrammetry

The Delta's remaining hardwood bottoms, the dissected Loess Hills along the bluff line, and the pine plantations of the Piney Woods are all the same problem for a camera: it sees the top of the trees. Photogrammetry builds a surface from overlapping images, and if the images show canopy, the surface is canopy. In a bare field it works well and often costs less. Over a timbered slough it gives you a model of the forest and nothing about the ground.

LiDAR fires enough pulses that some find gaps and return off the dirt. Those ground returns are classified out and used to build the bare-earth surface. That is the whole trick, and it is why we use the same drone LiDAR workflow whether the job is an open rice field or a cypress brake. For timber companies, the returns above ground give you a canopy height model and stand structure from the same flight.

What we deliver

Whatever your engineer works in. Standard products are a classified LAS or LAZ point cloud, a bare-earth DTM, a DSM, contours at any interval, an orthomosaic, cut-fill and stockpile volumetrics, and exports in DWG/DXF, GeoTIFF, shapefile, and PDF sheets.

Everything is processed in-house, not subcontracted, so the deliverable gets built to your specification. Coordinate system, contour interval, how breaklines get pulled — that is a conversation before we fly, not a change order after.

Accuracy, the honest version

We run an RTK base station on every mapping mission, set ground control points when the job calls for it, and collect independent checkshots so the numbers we report are measured, not assumed.

The tightest vertical accuracy comes on open ground with proper ground control — that covers the Delta case: leveled fields, pond levees, open impoundments — and we report the checkshot numbers so your engineer can see what the surface actually holds.

Under heavy canopy it degrades, because fewer pulses reach the ground and the surface is built from a thinner sample. Dense evergreen cover is the hardest case. That is a physical limit, not a settings problem, and we will tell you up front what your site will support rather than quote a number that doesn't hold over your timber.

Paragon is not a licensed surveying firm. We collect and process aerial data. Boundary surveys, plats, and any sealed document are work for a Mississippi-licensed PLS or PE, and we are clear about where our deliverable ends and theirs begins.

Who calls us in Mississippi

Civil engineers and land surveyors who need a dense existing-conditions surface faster than a crew can walk it. Farmers and ag consultants planning land leveling or drainage. Foresters and timber companies who need bare earth and canopy structure over a stand. Duck clubs and landowners building or rebuilding impoundment levees. Pipeline and oil and gas operators working corridors through bottomland. We also fly construction progress on the same trips, and in season, drone deer surveys for many of the same clients.

Getting on the schedule

We are based in Tuscaloosa, which puts most of Mississippi within a few hours, and the 24-foot command trailer and UTV go with us. Our pilots are FAA Part 107 certified and insured, and they are ours, not a contractor network. We have flown more than 53,000 acres of LiDAR, mapping, and site work in the last 12 months alone — more acres with LiDAR drones than just about any company in the South.

Send a boundary — an onX share link, a KML, or a shapefile — and tell us what the engineer needs on the other end. We will tell you what the site will support and what it costs.
