RIEGL system message: WARNG:OPTIME_FILE_IS_READ_FROM_BACKUP

The Cycle Log from a True View 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 True View encountered…

TerraMatch Adjusted Working Segments

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”…

Z Bump – Debias Operation Validity Testing

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…

Proximity Classifier Point Cloud Task

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…

Point Cloud Tasks

What is a Point Cloud Task (PCT)? A function (Extract ground, Conflate Line) that operates on points and/or vectors. A task can be a filter and/or an extractor. A filter classifies or changes the classification values for points (e.g. classify ground). An extractor extracts information from the point cloud data into vector, image or informational…

Noise Removal Options

Point cloud datasets will at times have noisier than usual low/high point noise that will need to be classified/removed from the project data. This can be caused by: vegetation, site movement (conveyor belts), water presence, etc. LP360 and True View Evo contain multiple methods available for removing this noise that are reviewed below, which can…

Invalid Value for Flush Interval

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…

Unable to display features in the profile or 3D view

Problem: When using the LP360 for ArcMap extension, the user cannot display features in the profile or 3D view. Probable Solution #1: Verify the spatial reference system (SRS), both horizontal and vertical, defined for the feature are correct and complete in reference to the point cloud. In order to display the feature properly, the feature…

Draw Failed: Interface not supported (9934)

User attempts to add WMS basemap and receives the error message, “Draw Failed: Interface not supported (9934)”. Despite projection being set for the project and nothing blocking the basemap download (firewall, anti-virus, etc.), the user is unable to display a basemap. Probable Resolution #1: User is currently in an RDP session. Solution is to: “Configure…
