Orthophotos can be used in different ways to help improve the data being shown.

Different Resolutions for different areas:

Sometimes an area is too big to have a fine resolution across everything, or it is desired to have more colour fill in the area around the point of interest, like the ground, rather than individual points and finer in the point of interest.

 

Here multiple orthophotos can be created at different resolutions.

In this case:

  1. In the settings set the point cloud rendering to be the desired output (like true colour).
  2. Turn off the main region containing the point of interest first.
    Note: The order of the point clouds should be the small point cloud first and then the larger one otherwise the larger orthophoto will cover the fine one.
  3. Create an orthophoto with a small pixel size.
  4. Turn off the smaller region and turn back on the other region(s).
  5. Capture the orthophoto at a higher pixel size.

This will fill in the gaps between the pixels for the ground, keeping a fine size for the point of interest.

 

Alternatively it may be desirable to have different colours for different areas to highlight certain aspects. In this situation using the above workflow, change the first setting of colour type in the tool for each orthophoto.

The example here is the cars are colour coded intensity at 0.01 for pixel size where the ground is greyscale at 0.09. This gives a distinctive difference between the two.

Note: Orthophoto outputs are limited to the ones set and region colour is not one.
