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.
OPUS is an online GNSS static data post-processing service. NOAA’s Online Positioning User Service (OPUS) provides free access to high-accuracy National Spatial Reference System (NSRS) coordinates. This service is occasionally unavailable so the following links can be used to post-process your static GNSS observation. CSRS-PPP Canadian Spatial Reference System (CSRS) Precise Point Positioning (PPP) is a service…
This post applies if your grid to ground conversion requires applying a horizontal scale about an origin point and is defined by: Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Scale based grid to ground transformations are probably the most common. If the origin point is not defined, it is usually implied…
Trying to run the Create Orthomosaic from Photo Package keeps prompting the user that, “Additional Python components are required. Run: ..\installPyYAML.bat”. However, that has been run already and running it again states, “Requirement already satisified: …in c:\users\%username%\appdata\roaming\python…”, where %username% is the Windows login of the user that ran the installPyYAML.bat the first time. Delete the…
The Create Seawall Feature tool, found on the LP360 feature edit toolbar, allows the user to create a contiguous polygon feature at the proper width/depth and height of a seawall (or any similar feature) contained in the point cloud. This function can be scaled to fit the specific scenario of the user: from simple walls…
When connect to a machine using RDP, adding a WMS backdrop to LP360 or True View EVO results in the message, “Drawing Map Complete” showing in the lower left-hand corner, but no image is displayed for the WMS layer. LP360 and True View EVO use OpenGL and Microsoft’s Remote Desktop only uses software OpenGL by…
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…
