9.2.2 Data logging.
[Back to contents]
Data logging destination drive.
The destination drive letter can be chosen, either before the logging buttons are pressed, or while data logging is
enabled. If a drive letter other than 'C' is chosen (in the yellow background control), then the software will check for a
valid drive connection and also that there is more than 1GB of storage space available. If either check fails, then the
data are logged by default to C. The directory structure described below will be used regardless of which drive letter id
selected.
A LAN shared drive, or a directly connected (and powered) USB drive can be selected. The drive letter, and the button
position will be saved and used at next program start up.
Logging to a drive other than the Lidar's C drive may reduce acquisition speed.
Data logging directory structure.
Data are logged using the following directory structures:
C:Lidar\Data\Proc\yyyy\yyyymm\yyyymmdd\ - for processed data
C:Lidar\Data\Raw\yyyy\yyyymm\yyyymmdd\ - for raw data
And with the following naming convention:
Stare_ID_yyyymmdd.hpl – for daily stare files (.raw for raw data files) where ID is the Lidar system ID
Stare_ID_yyyymmdd_hh.hpl – for hourly stare files (.raw for raw data files)
If the optional de-polarisation channel is fitted, then the directory structure will be as above with the additional 'cross'
directory.
For other scan types, the naming convention is as shown:
VAD_ID_yyyymmdd_hhmmss.hpl (.raw for raw data files)
Wind_Profile_ID_yyyymmdd_hhmmss.hpl
User1_ID_yyyymmdd_hhmmss.hpl
All data files are appended to, therefore reducing the risk of loss of data due to power failure. When copying data
from the Lidar – avoid copying any of the current log files as file sharing violations could occur.
