How this work actually goes.

Written for the people who have to buy it, use it, or defend a decision made with it. No vendor talk, no accuracy claims without the caveat, and a clear line between what capture data does and what a licensed professional does.

LiDAR or photogrammetry: which one your site actually needs

Pick by what the site is made of. Photogrammetry fails on canopy, fresh sand and water. LiDAR cannot tell you what a surface looks like. Most parcels here have both problems inside one boundary.

What to send your capture provider before the first flight

Send the boundary, the datum, the deliverable format, the tolerance, the access constraints and the real deadline. Six answers. Almost every capture project that goes sideways is missing one of them.

Documenting a coastal property before hurricane season

Fly the property in spring. After a storm, every conversation turns into an argument about what the roof looked like in June, and only one side of that argument can be proved.

Milestone inspections and SIRS: what reality capture can and cannot do

Aerial capture does not perform a milestone inspection and cannot. What it does is give the engineer who performs one detailed documentation of surfaces that are hard to reach, and give the board measured quantities instead of estimates.

Ground control and datum: why point clouds land in the wrong place

An accuracy number describes the sensor. Control describes whether the data landed where your project lives. Those are two different claims and only one of them is on most proposals.

What a digital twin actually answers on a restoration project

The flythrough impresses a board once. The measurements get used for two years. Only one of those is worth paying for, and it is not the video.

02/Ask directly

Not finding what you need?

If you have a question about whether capture data will support a decision you are about to make, ask it. We would rather tell you it will not than sell you a flight that does not answer the question.

05/Next step

Start with one site.

Send the boundary and the deliverable you need. We scope it, fly it, and return the data in your format, typically in under seven days.
