Do viewing and measuring 3D content consume my data usage?

Viewing and measuring 3D content do not count towards your standard imagery data allowance.


Will there be other measurement tools for 3D imagery?

The 3D tool set will be expanded over time. We would love to hear what tools you would like included in the future.


How do I know if my measurement line end point is at the spot I meant it to be at?

Lines will begin and end on the surface of the 3D mesh, when using the line tool a disc is used as a guide to the surface you are hovering over. This disc will reflect the surface slope and angles as you move over them and this can help you decide where to start and end your line.

Changing the camera position may also help you validate if you put the point where you wanted to put it, though at some angles seeing the line in front of the building may be confusing.


Why is the measurement different to the equivalent one I made on the Oblique map?

The most difficult part of measuring using either method is accurately picking the top and bottom of the object due to shadows, obstructed views and the limits of resolution. With practice behavior becomes more consistent, and in tests of measuring with both 3D and oblique images, results are consistently within about 1 meter of each other.


Which measurement is more accurate, 3D or Oblique?

The accuracy of the measurement tool is the same, so this will largely come down to how well the object in question has been resolved through either method and will vary from object to object. In practice the method that allows you to choose the top and bottom most clearly will likely result in the most accurate measurement.


Are my lines and measurements saved in projects?

Yes.
