Preparation
Exporting the 3D model, drawing the contour lines will be our goal. First we remove the trees and buildings from the original 3D.
Photogrammetry from drone Part2
Protogrammetry From Drone Survey
Goal
When information about a site is not available, it is interesting to make a survey by drone to realize a photogrammetry. The photogrammetry will allow to build a 3D model and to extract the necessary information to understand the site.
The preparation of the drone flight is essential. The flight must be able to cover the entire site from different angles. Otherwise, there would be deformations or missing information.
The example presented here presents the workflow for creating a 3D model from an aerial film shot with a drone and the processing of the data for further work.
Here, the drone was forced to work in sections. Here are the different views. The work to come will be to assemble the 3D file fragments. Continue la lecture

Setting up a custom environment in Spatial
This tutorial follows the requirements described on the Spatial.io web site here (https://support.spatial.io/hc/en-us/articles/360058728892-Custom-Environments-) and here (https://support.spatial.io/hc/en-us/articles/360042195672) but it describes more in details the setting up of the 3D model.
