Aerial survey · Perth, Western Australia

Data your surveyor will accept.

Aerial survey for mining, civil and agriculture. Every dataset ships with the control report that proves its accuracy — checkpoint residuals, control network, datum. Not adjectives.

04 / What proves it

Independent checkpoints left out of the adjustment. ±25 mm horizontal, ±40 mm vertical, and the residual at each one published in the control report.

What the aircraft records. A raw point cloud. Millions of measured returns, classified by nothing yet.

What it resolves into. The surface, with the ground separated from everything standing on it.

What it is tied to. Ground control, on GDA2020 / MGA Zone 50. Not a local grid that only agrees with itself.

What proves it. Independent checkpoints left out of the adjustment. ±25 mm horizontal, ±40 mm vertical, and the residual at each one published in the control report.

02 / The part nobody publishes

Every operator says survey-grade. We show you the residuals.

We checked the category before we built this. The strongest competitor in Perth claims “survey-grade accuracy” and “verified accuracy” and publishes no number anywhere — verified against what, to what tolerance, evidenced how? Your surveyor will ask exactly that, and an adjective is not an answer.

Every job we deliver ships with a control report: the control network we used, the independent checkpoints we deliberately left out of the adjustment, and the measured residual at each one. You can check our work. That is the whole idea.
