Importing control points
There are two ways to import control points:
- With the block import: control points can be part of the block definition. See also Import blocks
- With a control points text
file imported from the Surveys tab (Import button).
Supported formats are TXT/CSV and ContextCapture Surveys (XML).
A basic example of supported control points files is a simple TXT file listing control points 3D positions with XYZ coordinates separated by a space.
Control points text file sample:
GCP_A 315796.627695945 4869916.09237971 627.8 GCP_B 315332.029686681 4870703.80261219 738.9 GCP_C 315483.66078491 4870210.48269584 833.2 GCP_D 315399.200463097 4871212.13895964 906.5
Thanks to the import wizard, you can import a custom text format with delimiter-separated-values, including advanced property like accuracy.
When importing control points, please ensure you have selected the right spatial reference system (SRS) (See Set the spatial reference system).
