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.
User wishes to convert ASPSuite processed images to a NAD83(2011) projected coordinate systems in PhotoScan, but the desired NAD83(2011) based projected coordinate system does not appear in the list of available coordinate systems. To convert ASP processed images to NAD83(2011) projected coordinate systems in Photoscan, you must change to the NAD83(2011) geographic coordinate system in Reference…
Problem: Getting the error, “Getting x coordinate failed. (16881)“, when attempting to open the control point table from the LP360 Control Points toolbar. [Window Title] LP360 Error [Main Instruction] Getting x coordinate failed. (16881) [Expanded Information] Exception Information: HRESULT: 0x80040202 Source: “esri.Point” Description: The operation was attempted on an empty geometry. [V] Expand this […
If your organization has strict security settings, some of the executables installed and used by ASPSuite could get blocked and prevent ASPSuite from operating correctly. It may be necessary to get your IT department to add these executables to an approved list. The following instructions will show you how to find the executables being used…
Formatting the SD card through DJI Go 4 is useful when SD card space is needed and you do not want to remove the SD card from the aircraft (or personality cable). Be sure all important information has been downloaded before formatting the card because this process will erase everything. Here are the steps to…
Structure from Motion (SfM) algorithms used by image -to-point cloud applications require strong overlap to create an accurate 3D model. Missions should be planned to include both forward overlap, and side overlap. To achieve this, the mission must have at least two flights lines, but more is better.
It is always best practice to submit your static base observation data to an online post-processing service to obtain the position of your base station. However, it is possible to process your Loki data with a base coordinate that has not been processed. If a base position is needed to check for a fixed solution…
The answer to this question will depend on the Structure from Motion software being used. The two primary components are: The ability to use high-accuracy geotags. Loki provides highly accurate geotagged images with accuracy values written to the XMP metadata. We also produce a simple .csv text file for applications unable to read that…
Prolog: I am writing a new whitepaper on model constraints in LP360 (any reference to LP360 where I do not add the term “for ArcGIS,” I am talking about the standalone version. This document is extracted and heavily revised from a series of articles that I wrote for the GeoCue Group Newsletter in 2013. The…
Using Loki, AirGon’s precision positioning system, very accurate georeferenced imagery can be collected using DJI drones over an area of interest. The positions from which those photos are captured are output from the ASP Suite workflow as geographic locations, described by latitude, longitude, and altitude coordinates. Image-to-point cloud software applications such as Agisoft PhotoScan and…
