GeoCue’s repository of TrueView tools, tips and workflows for the TrueView line of drone mapping products. Includes former AirGon products such as Loki and ASPSuite.
The Cycle Log from a TrueView 3DIS containing a Riegl laser scanner contains a diagnostic message (DIAG), “RIEGL system message: WARNG:OPTIME_FILE_IS_READ_FROM_BACKUP”. This is a warning message from the Riegl laser scanner that can result if the scanner was not shut down properly during the previous run. This can happen if the TrueView encountered a hard…
A common practice amongst GeoCue customers (and internally) is to use previously established control points to compare with an sUAS produced point cloud to gather absolute accuracy statistics. The vertical mean error from these statistics is often used to “Debias” a dataset. This is simply shifting the point cloud data to match the measured control…
The Proximity Classifier Point Cloud Task found in LP360 and True View EVO classifies points based on attributes of a proximal point. A couple of use case scenarios could be: Classifying a new dataset based on an older one for datasets from multiple collect times. Classifying a subset of a larger dataset, then incorporating the…
Attempting to modify any project setting in LP360 or True View EVO results in an error stating, “Invalid value for flush interval. Must be a valid positive number.” Upgrade to v2020.2.33.3 or later to avoid encountering this error. This was a bug we introduced when we introduced the new diagnostics logging tab in the v2020.2.33.0…
Attempting to install the C:\Program Files\Common Files\LP360\MSPy\installPyYAML.bat as part of configuring the Create Ortho from Photo Package tool in True View EVO version 2020.2.33.0 or earlier results in, “Error: PyYAML-5.3.1-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform” Metashape Pro v1.7.x was released after True View EVO v2020.2.33.0, hence, it is not supported in that…
Once the POSPac trajectory batch processing has completed, you will be prompted to view the POSPac report. Click Yes to view the POSPac Report, or No to move to the next step. You may reopen the POSPac report at any time by selecting View Post Process Trajectory Report on the TrueView Utilities toolbar. There are…
Retained Photo Station Layer Settings allows the user to specify the photos to be kept for geotagging and export to photogrammetic software packages using Export Photo Package. The notion of “Retained Photo Stations” creates a layer of photo stations (remember for a True View 3DIS there are two photos per photo station) on a new…
GeoCue Group’s ASPSuite includes all the software needed to import support files, process the Loki observations in Post-Process Kinematic (PPK) mode, process Phantom 4 RTK in PPK and Real-Time Kinematic (RTK) modes, and update image headers with the refined position information. The ASPSuite User Guide will discuss the workflow starting with checking the data in…
Problem: Attempting to auto-download the ephemeris and navigation files in ASPSuite or True View EVO results in, “Unable to download GPS Ephemeris and Navigation Files. The remote server returned an error: 227 Entering Passive Mode.” Verify your internet connection and try the download again later when the files may be available as they may not be…
