Good morning every one,
In our company we got Trimble TDC 100 and install Qflied for data collection. We collect points and polylines. Our aim is to get vertex and points while saving their altitude ( height above the mean sea level ).
When we work on the desktop project, we enable the "Z". But after the field collection, Z($geometry) just products " 0 " not the altitude. Please how to solve this issue ?
