When using a True View 3D imaging system, what check point recommendations do you have? Check points should always be used to validate the absolute positional accuracy of imaging and 3D imaging projects. We follow the ASPRS Digital Accuracy Standards, Annex C. Its an older standard than most UAV mapping so you’ll find that it’s…
LP360 has several very useful command line executable utilities that can be used to simplify different tasks or improve the efficiency of large batch processes when working with substantial amounts of data or repeating processes. LDExport was added to this utility catalog with 2017.1. It simplifies the export of LAS points and surfaces, for example…
This post applies if your grid to ground conversion requires needing to apply a horizontal rotation about an origin point and is defined by: Horizontal Translation North (tN) Horizontal Translation East (tE) Horizontal Rotation (Rz) Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Then, if the horizontal scale factor is one, luckily,…
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…
GeoCue 2020 If TerraScan, or TerraSlave, is installed in a location other than the default then for each machine where this is the case edit the Machine Properties in Dispatch Manager to add the Non-Standard EXE Location to enable GeoCue to find the TSlave or TerraSlave executable when needed. The executable and user preference, TSlave.UPF,…
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…
In GeoCue, when populating another layer of working segments, generating LIDAR orthos, or LIDARgrammetry stereo pairs from a layer, where that source layer has been adjusted using TerraMatch after the population of those source working segments, one might notice some slivers of missing data that follow the boundaries of the source working segments. The “gap”…
