In some case, we need the ground terrain contour without vegetation effect.
Therefore, We firstly remove the point clouds of the high vegetation area and hope to get the ground contour for that area using interpolation calculations.
However, the operation of Pix4D’s contour generator seems not to use interpolation method with considerations of the surrounding terrain, but to set the lowest elevation of the project as the ground terrain for the high vegetation area, whose point clouds has been removed.
We would like to ask for your suggestion on the problem of Pix4D’s default setting as abovementioned. Is it possible to generate the ground contour for certain regions using interpolation method?
