I am trying to do a 3D model with vegetation over a 50x50m grid over a specific point. I wasn’t able to collect a GCP so I am depending on only the camera/phantom altitude and geolocation data available. I have been noticing as I am processing the data that there is an overall shade gradient that I don’t necessarily think is an accurate depiction and leading to perhaps some inaccuracies in the data. Is there a way to get a better understanding of the vegetation heights/topography of the landscape without GCPs?
I have attached a couple images from a specific project. You can see the ridges of vegetation and water dispersed in the landscape but those instances aren’t necessarily depicted in the imagery/DSM because there is an overall gradient in the imagery and I have this is every single project!
Thank you so much for your help in advance!
