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.
Problem: In ASPSuite, processing the Interpolating Camera Events step results in an, “Error: Rover Position File (.pos) is Empty”. Probable Solution #1: The base station coordinate was entered incorrectly. Check the base station coordinate and be sure that southern latitudes and western longitudes have a negative sign. Note the base station must be entered in…
LP360 can be inefficient when working with very dense point clouds, such as Dense Image Matching, for ground classification if appropriate steps are not taken in the workflow. In fact, be aware that it simply crashes if you have to use a large seed size (e.g. 200 feet on some machines) that requires more points…
Problem: A check of the ASPSuite License shows Current License as “Unlicensed” and shows Available Licenses as “0 of 0”, but the Check Out License button is enabled. Attempting to check out a license in this state will result in an error, “Failed to checkout roaming license. Failed to checkout the license for ASP. Reason:…
Beginning with version 2017.1 of LP360, users have the capability to edit the attributes (Add fields and values) of shapefiles. In LP360, fields are added/removed via the Schema Editor and values modified using Feature Analyst: The Schema editor is used to manage the fields of the shapefile, hence it is used to add/remove fields: A…
Reckon has been deprecated and replaced by LP360 Online, including the LP360 Portal and LP360 Cloud. Viewing uploaded images on the Reckon website is a great way to view orthomosaics and hillshades. If a user needs to download an image, to view it offline, or in LP360, this can be accomplished by downloading the image…
Classify by Features is a useful way of assigning classifications to points using a spatial relationship to other features. Any vector layer that exists in the Map can be used to classify points that are either within a specified distance of polygon, linear, or point features or any points completely within a polygon feature. 1.…
When importing adjusted photo heights into PhotoScan, the photo name is used to attach the adjusted image height to the photo in the PhotoScan project. The photo numbering system used by DJI aircraft starts at DJI_ 0001 and goes up to DJI_0999. When the number of photos exceeds DJI_0999, the photo count starts back over…
This workflow is for AirGon Drone Mapping Suite customers who do not use Loki and instead use ground control points for accuracy. To process images in PhotoScan using control points, it is important for the image heights to be relative to the same vertical datum as the control points. Some drone models cannot determine their…
One of the steps in AirGon’s PhotoScan processing workflow is to build a 3D mesh. The mesh building step usually consumes more memory than other steps in the workflow and can lead to a memory error if the capacity is exceeded. The source of this problem can sometimes be traced back to the selection of…
