Coordinate Reference Systems (CRS)
The Coordinate Reference System (CRS) refers to which geospatial reference system is used to assign horizontal coordinates and vertical elevation values to visualized data.
A CRS establishes the relationship between the 2D information and the actual physical world location using the coordinates.
2. Set Site CRS
Setting the CRS used for a Site is the first step to take when creating a Site on Aether.
The Site CRS can be defined in a couple of ways:
- During the Site Creation.
- Or later in the Site Info Panel (manager role required)
3. Set image CRS
Set image CRS when uploading a survey (Upload Survey), or after the selected images have been uploaded.
- If the picture has metadata, the input CRS will be filled automatically.
- If not, after adding the geolocation coordinates file (generally in a CSV file format), choose the appropriate formatting source and the File CRS :
4. Photogrammetry CRS
Every time a user requests photogrammetry processing, Aether will always request the desired output CRS system.
5. Consult the Site CRS
The site CRS is displayed on the Site Info Panel.
