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.
When using Loki with the Inspire 2 Personality cable, DSLR cable, or direct hardwire camera cable, the number of external events recorded can be confirmed by opening the sbf.blocks.txt file in the PPK folder in the ASPSuite project folder (root folder). There should be a block (highlighted in the image above) that begins with “#…
Attempting to run POSPacCloud to process the trajectory solution for a True View 410 results in an error message stating, “POSBAT_PARSE_FAILED”. POSPacCloud has a limitation in that not only can it not handle accented characters in the path, but it also cannot handle the regional settings where a comma is used instead of a decimal.…
When attempting to convert point coordinates from one horizontal projection to another using LP360 or True View EVO, the user may see a warning message with the heading: “Datum Transform Warning!” if the datums of the projections differ or appear to differ based on their WKT. Before attempting to perform any coordinate system transformation/reprojection, it…
The user is receiving the following error message during POSPac processing in the True View EVO software: {“status”: “TDCOMPRESS_FAILED”,“message”: “Error in compressing project data”,“data”: null} This error is caused by the current lack of support in POSPac processing for accented characters. If your chosen file path has an accented character, this error message will appear.…
What is POSPac? True View 3D imaging System (3DIS) uses Applanix APX Position and Orientation Systems (POS). The POS is a GNSS-aided Inertial Navigation System that provides the precise position and orientation of the sensor at a rate of 200 observations per second. This information is needed to “geocode” LIDAR and determine the exterior orientation of images. Applanix…
To use the SBF file (Loki file), ASPSuite will convert it into Rinex observation and navigation files during the file conversion step (Step 2). If the SBF file has not been converted, and the observation and navigation files are not in the project folder, the error, “Loki Rover Observation and Navigation Files do not exist:”,…
ASPSuite has the ability to filter out GNSS satellites based on elevation mask, and Signal-to-noise ratio (SNR) mask. Before reprocessing with increased mask settings, it is good practice to check the number of valid satellites used in the solution. The following steps describe the process for checking the number of valid satellites used in the…
A DJI gimbal is not pointing forward properly for mapping flights. The top of the camera is slightly skewed to one direction. Please change the following settings in DJI GO or GO 4 depending on your drone configuration: In SmoothTrack Settings, Change Deadband – Pan to “0” and Speed – Pan to “100”. In Movement…
User sees large voids when displaying point cloud data in LP360. This usually occurs when combining dense and sparse point cloud datasets or displaying terrestrial scanner points clouds. The reason points don’t display properly is that points close to each other spatially are not physically near to one another in the LAS file structure. Here…
