Trimble CenterPoint RTX in POSPac for TrueView 3DIS

Trimble CenterPoint RTX © is a global GNSS technology that provides centimeter-level positioning, worldwide, at any time. Users may use this service, much like the United States NOAA’s Online Positioning User Service (OPUS), or other national and private services, and submit a base station RINEX file to obtain a coordinate for that survey nail/reference mark,…

Convert TPS to RINEX

To convert raw TopCon base observation files to the RINEX format, it is best to use a custom profile to ensure the RINEX file header contains the necessary information for TrueView EVO/LP360 Drone and POSPac to correctly process data from the base station. To convert your TPS files to RINEX, you will first need to…

Converting Raster Data to Local Coordinate Systems

End users may require point cloud and raster deliverables in local coordinate systems, aka ground coordinates or local site calibrations, or to debias an orthomosaic to control. In addition to the Reproject LAS PCT, TrueView EVO/LP360 Drone has the capability to scale, translate and rotate point clouds to a variety of local coordinate systems by…

TrueView Error: UPLOAD_FAILED

While attempting to run POSPacCloud to process the trajectory solution for a TrueView 3DIS, the user encounters an error message stating, “UPLOAD_FAILED”. Update to TrueView EVO/LP360 Drone v2022.1.39.0 or later and install POSPacCloud v0.0.67 or later. Both installers are available from the Downloads -> Software section when you log into your Reckon account website. These…

Setting the start/end time of POSPac Processing

This procedure applies to users running POSPac Desktop (Classic) processing and is not applicable to POSPacCloud or DGaaS sensors. LP360 Drone will attempt to automatically set the start/end time of POSPac sensor trajectory processing based on the kinematic motion of the sensor. This works in the vast majority of cases. However, there are times where…

Creating dz Images

Relative vertical accuracy, or flight line offsets, or the swath-to-swath fit between flight lines or drive passes can be qualitatively assessed using dz images. Or quantitatively assessed by exporting and analyzing the values. The USGS LiDAR Base Specification has evolved over the years with some different recommendations for evaluating interswath (overlap) consistency, and there are…

Error Updating Project Catalog

Attempting to save an LP360 project results in “An error occurred updating the Project Catalog with Project:”, followed by “Detail: Error: Unable to open Projects File. Project not added to list. C:\ProgramData\LP360\PMProjects.json”. The global projects file, “%ProgramData%\LP360\PMProjects.json”, used by the LP360 Project Manager was created with administrator permissions when LP360 or TrueView EVO first launched…

Building Filter and Extraction for dense datasets

Some LP360 Point Cloud Tasks (PCT’s) were originally designed for older manned lidar datasets, which have significantly lower point density than modern sUAS datasets. TrueView and other sUAS sensors have the capability of producing much denser point clouds, so these processes can take much longer if running on the entire dataset. A common strategy and workflow…

Processing TrueView Images in TerraPhoto

TrueView 3DIS (3D Imaging Systems) produce images and positional information which can be imported into TerraPhoto for orthomosaic generation, point cloud colorization, powerline workflow – image view, etc. Here we’ll review the process for importing this data into TerraPhoto, which includes: exporting a photo package from TrueView Evo/LP360 Drone, rename the images for import into…

MfE: “Warning: disabled reference records with zero GPS coordinates”

Running Metashape for EVO (MfE) errs almost immediately with a warning in the STDERR section of the processing log that states, “Warning: disabled [m/n] reference records with zero GPS coordinates”. The warning indicates there are one or more photocenters included in the layers submitted for the MfE job where the GPS Coordinates in the EXIF…
