You can view Nearmap 3D content in Cesium format in MapBrowser. This MapBrowser functionality is sometimes referred to as 3D Viewer.

To view 3D you need specific Nearmap subscription offerings. Please contact your Nearmap Account manager to enable this option.

Viewing 3D Imagery

You can view 3D imagery in MapBrowser by selecting 3D from the drop-down list above the compass:

Understanding 3D Capture Dates

Each 3D capture is made up of multiple surveys, flown at different dates. The capture name at the bottom of the screen consists of the region of the capture and the month and year of the first survey in the capture.

The entire scene could be made up of photos taken over one to three months.

Navigating the 3D Imagery

When using a standard two-button mouse with a scroll wheel:

  • Panning is achieved via the left mouse button
  • Tilting and rotating is achieved via the right mouse button
  • Zooming can be done by scrolling the scroll wheel

When using a laptop multi-touch touch-pad:

  • Pan using any part of the touch-pad with one finger
  • Tilt and rotate while holding the ‘Alt’ key (Windows) or the 'control' key (Mac) and using one finger on any part of the touch-pad
  • Zoom by sliding two fingers up and down the touch-pad.

3D Imagery Constraints

Because of the unique nature of capturing 3D imagery, we have a few constraints:

  • Photogrammetric 3D relies on surface reflectivity to resolve objects. Highly reflective surfaces and areas of dark shadow will result in holes and distortion. 
  • The viewable reconstructed 3D scene is actually a continuous surface. Individual objects are not extracted, so we see some blending or smooth interpolated surface between objects and where we would normally expect to see hard angles.
  • Urban canyons and narrow alleyways usually do not receive much sunlight and Nearmap's cameras find it very difficult to see detail at street level between tall buildings. As a result our 3D scene lacks detail at these locations.

3D Imagery Resolution

The geometry of the 3D scene is constructed using a 15cm ground sampling distance. Textures are applied to the geometry using our standard images with a resolution of less than 7.5cm. The ability to resolve objects is a function of size, shape and surface reflectivity. We expect to be able to resolve objects that are greater than 40cm in size, are not long and thin and are not highly reflective.
