I'm looking for a way to do an elevation heat map relative to ground surface.

Hey all, first time poster here. I’m working on a project that has the remains of some old stone foundations, using the point cloud I’ve created a sort of elevation heat map with the point cloud, but it is relative to actual elevation, I would like to have those foundations ‘pop’ a little better using the elevation relative to the actual ground. I’ll attach an example, it shows the color by elevation but relative to actual elevation. I need colors to differentiated relative to elevation above ground. Anyone have any ideas?

Hi Ryan,

I just came across your post now so not sure if you have resolved your issue but I will try to assist in case you haven’t solved it.

The only way I can see this working in Matic is on flat terrain only which will not work in your example.

The other Pix4D solution I can think of other than using Mapper, is you could import your Matic project into Pix4D Survey, classify the terrain and non-terrain and choose two different colors to make your foundations pop.

See example blow:

However, Pix4D Survey will only give you one solid color for the non-terrain features. If you want the non-terrain elevation features to have a different elevation colors above ground, you would need to use a different software like QGIS or Global Mapper.

I use Global Mapper for this and you can see the same sample data area with the elevation colors relative to the ground below.

Please let me know if this makes sense.

Regards,
Craig
