C.A.Ts and Gennys are used to survey an area prior and during an excavation. Depending on the complexity of the area surveyed it is normal for C.A.T operators to perform a large number of scans in different modes.
All the scans preformed to survey an area are grouped into a single Survey.
Automatic Survey grouping
The C.A.T Manager Online system automatically groups different scans into survey as they are received.
The C.A.T Manager server looks at time difference and distance between subsequent scans. Scans which are within 30 minutes or 30m apart are considered part of the same survey.
Manual Survey creation
C.A.T field operators may want to start and stop a survey manually to ensure that only the correct scans are part of the survey being conducted and which will be monitored and analysed by their supervisor
For example if before starting a survey, the gC.A.T4 is tested in different modes and with its Genny in the same area in which the survey will be conducted, these “test” scans may be considered as a part of the same survey by the C.A.T Manager Online system.
You can start or end a survey directly from the home screen surveys screen:
NOTE: the survey will automatically close after 90min of inactivity
You can resume the previous survey, if this was ended no longer than 6 hours earlier, or just start and end a new one from the Manage surveys screen:
The survey will start and wait for the first scan to become active.
When a survey become active this will appear the first scan is received the survey become active and appear in the history window
NOTE: the app will warn you if you are trying to close a survey with no scan associated with it
