During our March TrueView Training event, we recorded the training session with the presenter to have the training material available on demand. Since the training covers two days of various topics we have broken the event down into smaller pieces. This session covers model key points, deliverables such as contours, exporting data, uploading to Reckon,…
A short tutorial covering the Phantom 4 Pro (P4P-RTK) Post Processing Kinematic (PPK) workflow in TrueView EVO/LP360 Drone. The workflow covers some background on the workflow, the data files you need from your P4-RTK guest sensor, PPK trajectory processing, automated and integrated Agisoft Metashape processing to create an orthomosaic and dense image matching (DIM) point…
If you are not accustomed to survey techniques, this is a quick tip for speeding up visits to repetitive sites. The AirGon Loki Direct Geopositioning system is a huge time saver when it comes to drone survey work. Loki reduces or eliminates the need for ground control points (but please, always have a reliable way…
We get a lot of questions regarding accuracy in drone mapping projects. These questions range from ground control layout suggestions to the necessity of calibration cameras. Sometimes it is useful to step back a bit and take a wholistic view of the elements that impact photogrammetric accuracy. The information in this article is meant…
The density of point clouds (usually expressed as points per square meter) is increasing on what seems to be a monthly basis. This is particularly true of point clouds derived from Dense Image Matching (DIM), the clouds produced from software such as PhotoScan, Pix4D, DroneDeploy and so forth. You can quickly check the density of…
A Case Study from Philips’ Soil Challenge We conduct a core product inventory every quarter for our bark and pumice stockpiles to keep our bookkeeping updated. Our inventory collection methods consisted of simply guessing the volume of each pile (highly inaccurate) or having our loader operator move 5 yards of product at a time (extremely…
