Vertical Aspect – Interview in AAPG Explorer Magazine

Vertical Aspect was recently interviewed by the AAPG (American Association of Petroleum Geologists) trade publication “Explorer”. The article refers to automation in drone technology; Regulatory Hurdles Effects on the Workplace Technological Limitations   … and even says something nice about Lady Gaga…   You can read it here at…   https://www.aapg.org/publications/news/explorer/details/Articleid/37814/the-future-is-automated  

Ground Control Points (GCP) & Check Shots in Pix4D

This video explains the difference between Ground Control Points (GCP) and check shots and how to use both of them within Pix4D Pro Mapper software to obtain survey grade accuracy Attributes of GCPs and Check Points GCPs are used to rotate, scale and orientate the project in a real world location or in some cases in a “Local Coordinate System) GCPs are typically statically placed around the outside edge of the project with at least one GCP in the interior of the project GCPs should not be more than 1,000-1,500 …

Drone Mapping Accuracy – Part II – Real Time Kinematics (RTK)

In an earlier post, we discussed Ground Control Points as a primary method of obtaining survey grade accuracy from drone mapping.  The photogrammetry/mapping software (such as Pix4d Pro Mapper) uses these GCP to make adjustments to the project to obtain survey grade accuracy.  However, this method requires laying out and precisely geolocating numerous control points (approximately every 1000 to 1500 feet).  Depending on the terrain and/or the size of the project, the GCP method could be very impractical, difficult and time consuming. Another, arguably more advanced method, is referred to …

Components for Drone Mapping

In this article we cover what’s actually needed – both in terms of hardware and software products, as well as the training and other items necessary to generate UAV mapping products. 1. Drone (UAV) – Fixed Wing or Multirotor Multirotors are a great initial platform – they’re less expensive, easier to fly and the smaller datasets (due to the smaller area covered) are faster to process. A DJI Phantom 3 Advanced or Pro makes a great low-cost starter platform, while a Phantom 4 Pro is not significantly more expensive and …
