SurveyFy — Real Estate Topography

Bathymetric surveys, above and below the waterline.

Our own hydrographic drone maps the bottom of lakes, ponds, canals and marinas while LiDAR captures the banks, seawalls and docks — merged into one signed and sealed plan with contours, cross sections and dredging volumes.

Tell us the waterbody, where it is and what the permit or the engineer needs. A licensed surveyor scopes it and replies with a price and a date.

Sonar, LiDAR, GNSS — one crew, one surface.

The same licensed team runs the hydrographic drone, captures the shore and seals the plan, so the underwater and the upland data always fit together.

  1. 01 · Capture

    Hydrographic drone and LiDAR

    The unmanned survey vessel runs planned lines with RTK positioning and a single-beam or multibeam echosounder; a drone or LiDAR captures the banks, seawalls, docks and structures on the same control.

  2. 02 · Process

    Merged surface and volumes

    Surveyfy AI merges the sonar and the LiDAR into one surface, draws the contours and cross sections and calculates volumes to the dredge template or between surveys.

  3. 03 · Deliver

    Sealed plan and CAD files

    Bathymetric plan with contours and spot depths, sections, volume report and Civil 3D surface — signed and sealed by a Florida PSM, typically in 5 to 10 business days.

What a SurveyFy bathymetric survey includes

The plan, the surface and the numbers the engineer, the dredging contractor and the permitting agency need.

  • Bathymetric plan contours and spot depths referenced to NAVD 88 or the datum the permit requires
  • Shoreline, seawalls, docks and structures captured with LiDAR or drone on the same control as the bottom
  • Cross sections at the stations and intervals your engineer or the permit specifies
  • Dredging volumes to template, between surveys or by area, in a signed report
  • Civil 3D surface and DWG merged bathymetry and topography, ready for design
  • Signed & sealed deliverables PDF and CAD by a Florida Professional Surveyor & Mapper

Our own vessel, our own crew — no subcontracted sonar.

Most land surveyors hire out the underwater part and stitch the results together later. SurveyFy owns the hydrographic drone and runs it with the same crew that captures the shore, so the bottom, the banks and the structures come back on one datum, on one plan, from one responsible surveyor.

  • Lakes, ponds and retention areas for capacity, maintenance and dredging design
  • Canals, channels and marinas with docks, pilings and seawalls captured above the water
  • Pre- and post-dredge surveys with volume reconciliation for pay applications and permits

For the people who design, dredge and permit on the water.

We deliver on the datum and in the format your project requires and coordinate directly with the engineer and the contractor.

Surveyfy AI · in-house software

Sonar below, LiDAR above — one surface in Surveyfy AI.

The hydrographic drone captures the bottom while LiDAR and drones capture the banks, seawalls and structures. Surveyfy AI merges both into a single surface, draws the contours and calculates dredging volumes — and a Florida PSM checks and seals the result.

  • Merged surfaceBathymetry and topography on one TIN, one datum, one plan.
  • Dredging volumesCut to template, slope quantities and material reports for the permit.
  • Cross sectionsChannel, canal and seawall sections at the intervals the engineer needs.
  • Change detectionCompare surveys over time to document shoaling, scour or dredge progress.

Every output is verifiable, signed and sealed by a Florida Professional Surveyor & Mapper.

What is the difference between a bathymetric and a hydrographic survey?

A bathymetric survey measures the depth and shape of the bottom of a waterbody. A hydrographic survey also maps the shoreline, structures and features above and around the water. We deliver both on one plan, on one datum.

How do you survey a small lake or pond?

With our unmanned hydrographic drone: it runs planned lines with RTK positioning and an echosounder, needs only shore access, and covers a typical retention pond in a few hours. The banks are captured with LiDAR or drone on the same control.

Can you calculate dredging volumes?

Yes. We compute volumes to a dredge template, between two surveys (pre- and post-dredge) or by area, and deliver a signed volume report with the plan and the Civil 3D surface.

What datum do you use?

NAVD 88 by default, with the conversion to NGVD 29 or mean low water when the permit or the agency requires it. Horizontal control is Florida State Plane.

What do you need to quote?

The location and approximate size of the waterbody, what the survey is for (dredging, design, permit, capacity) and any requirement from the engineer or the agency. We reply within 24 hours.
