How can i select some point from txt file using formula operator and delete by CALC_ATTR_FORMULA ?

DANBRI

Hi all
I have an RMSE report in "csv" format obtained by LIDAR_COMPARE based on a "txt" format 3D control point file

using CALC_ATTR_FORMULA in the scripting language, I need:

1. To eliminate all the points that have an RMSE> = 3 * "global_RMSE" in the RMSE report "csv" and edit the 3D control point file by eliminating the same point.

2. Recalculate a new global RMSE with the new 3D control point  file and generate a new report.
