Drone survey showcase

Measure the 3D model yourself

This is the same light web model of Anna's block as on the showcase page. Choose a measuring tool and click on the model to check a fence line, how far a shed is from the house, the fall of a paddock from top to bottom, or the area of a paddock or a building's footprint.

Measure it

Choose Distance or Area, then click points on the model. Clear removes every measurement, and Esc cancels the one in progress.

How to measure

Distance — choose Distance, click two points. The readout shows the distance along the ground, how much higher or lower the second point is, and the straight-line distance between them.
Area — choose Area, click the corners in order, then click the first corner again to close the shape (on a computer, double-clicking the last corner works too). The readout shows the plan area (the area as it would be drawn on a map), the distance round the edge, and the number of corners.
Moving around — drag to turn, right-drag or use two fingers to move, and scroll or pinch to zoom.
Accuracy tip — zoom in and look at the surface you are measuring face-on. A point clicked on a surface seen at a shallow, glancing angle can land a little way along it, because one screen pixel covers more ground there.

The model download is about 4.4 MB, and the 3D viewer itself is a larger download, so the page can take a moment on a slow connection.

What the model can and cannot tell you

The model has 119,561 triangles, a 4096-pixel photo texture, and was made from 1,301 drone photos. It has been cut to Anna's own land, with neighbouring properties removed.

The model is simplified for the web to roughly one point per 1.4 square metres. That is enough to measure paddocks, fence lines, tracks and building footprints well, but anything smaller than about a metre has been smoothed away. The full survey model we make for a client has centimetre-level detail; this page is a demonstration of the measuring, not of the full detail.

Heights are differences only

This model reports how much higher or lower one point is than another. It does not give a height above sea level, because an absolute height needs a vertical reference that the web model does not carry.

Not cadastral surveying

This is not cadastral surveying. Geomap NZ does not do boundary or cadastral work — that's a licensed cadastral surveyor's job.
