Reservoir feasibility topographic mapping

Existing-conditions topographic mapping for a dam-rehabilitation feasibility study: DSM, DTM, half-foot contours, and checkpoint documentation. Outputs are not a boundary or recordable survey and are not for engineering reliance without licensed review and acceptance.

TYPICAL DELIVERY

Feasibility studies live or die on the quality of the existing-conditions surface. In this representative scenario, aerial topographic mapping documents visible existing conditions across the impoundment, the dam face, and the spillway approaches in one mobilization. Client- or PLS-supplied control and boundary information define the capture and testing plan.

A DSM, DTM, contours, orthomosaic, and checkpoint report may support feasibility review, but Outlook UAS does not provide a boundary or recordable survey. A licensed professional must independently review and accept any output before engineering, permitting, or other reliance.

Scope & deliverables.

Capture

Single mobilization · client- or PLS-supplied control and independent checkpoints · PPK flight over impoundment and structures

Deliverables

DSM · bare-earth DTM · half-foot contours · orthomosaic · RMSE documentation

Turnaround

Typical four days from capture to the full deliverable package

Reliance boundary

Not a boundary or recordable survey · licensed review and acceptance required before engineering or permitting use

How accuracy was held.

Tested to ASPRS. Client- or PLS-supplied ground control and independent checkpoints support a measured RMSE, computed and documented for the study record. ASPRS terminology describes the positional workflow only; it does not confer professional-survey status or establish suitability for engineering reliance.

Delivery commitments.

Standard-scope deliverables are typically available in the portal within 24 hours of flight; larger, survey-tested, or multisensor scopes receive quoted timeline.
Free reprocessing, revision, and re-delivery for the life of the project, within original scope.
Data is processed in the field and checked for completeness before demobilization (coverage, overlap, control residuals); final validation follows the stated delivery method.
