TrueView Sensor Tab
The TrueView Workflow Toolbar processes data collected from a GeoCue TrueView sensor.
There are three positioning modes available for processing TrueView 3D Imaging Sensor (3DIS ) data. These modes are:
-
Single Base – a single base station has been set up at or near the project. Alternatively, a single remote base station (such as a member of a Continuously Operating Reference System, CORS) will be employed.
-
Smart Base – a virtual base station from the Applanix SmartBase service will be employed
-
PP-RTX – Precise Point Positioning from the Trimble PP-RTX service will be used
Best PracticeSet a local base station near the takeoff location of the drone. You must observe for at least 5 minutes prior to startup of the TrueView system to at least 5 minutes after shutdown. If practical, an observation session over two hours is preferred since it allows for a more accurate position estimate. Rely on SmartBase and PP-RTX as backups for project recovery in the event something happens with your local base station. |
There are three collection modes available with a TrueView 3DIS:
-
LIDAR and Cameras (3DIS mode) – this is the default data capture mode
-
LIDAR only
-
Cameras only
Prior to starting data processing, you should verify the following:
-
The source data collected in the field is available either (a) on the USM memory stick from the sensor now attached to the processing computer or (b) has been copied to a folder on the processing computer or local network.
-
The base station observation file, if using a local base station, has been downloaded in RINEX format and either (a) copied to a local folder on the processing machine or (b) copied to the “Cycle_xxxxxx_yyyyyy\System” folder of the flight, either on the USM or in the local folder. Copying the observation file to the Cycle\System folder of a flight will automatically associate that file with that flight and include it in any processing. The observation file must be in RINEX 2.11 format or later.
-
The base station details are known; latitude/longitude/elevation (in ellipsoid meters) of the reference point, the manufacturer make/model of the hardware and the input frame of reference (including epoch) to be used in processing the trajectory.
-
The spatial reference system (coordinate system) to be used for the project. This should be the output SRS you want for your deliverable data set.
