Dense vegetation vs. quality topography output

Hi All,

We are looking to survey a particular land plot which is particularly flat but has very dense mangrove vegetation.

The contractor is asking how accurate will the topography model/output wil be?

We are located in Grand Cayman and a google satellite image of the interior of the island will show you what we are working with.

I look forward to your feedback.

Thanks,
Tim (AirVu)

Tim,
With my experience, the topo of a densely vegetated area will be of the tops of the trees or shrubs.

Hi Tim,

Dense vegetation is hard to map. check this out: https://support.pix4d.com/hc/en-us/articles/202560159
The accuracy depends on how many images will get calibrated and what is the spatial resolution of your images: https://support.pix4d.com/hc/en-us/articles/202558889

hope it helps,
