Metashape for EVO (MfE) 

We have built interfaces directly into our drone mapping processing software, True View EVO, for driving both an embedded version of Metashape (Metashape for EVO, MfE) as well as the full GUI version of Metashape Professional.  This design provides a seamless photogrammetric workflow for users of EVO processing software. 

Metashape for EVO supports the generation of:

  • Block Bundle Adjusted (BBA) imagery for improving positional accuracy
  • Point clouds from imagery (“structure from motion”) – typically used in DJI camera workflows
  • Orthomosaics

StripAlign for EVO (SAfE) 

Data can exhibit small geometric inconsistence, especially when combining data from multiple flights.  BayesMap StripAlign for EVO detects and corrects these errors via an application of sensor-specific mathematical modeling.  SAfE is a fully automated process with no need for users to set project-specific “tuning” parameters or to move in and out of the EVO processing environment – press a button and it works!

Our True View 3D Imaging Sensors were designed as a lightweight payload to allow flexible integrations on numerous drone platforms. We have worked with several drone providers to provide customers the complete drone mapping solution they are looking for. Don't see the company you're looking for, contact our team and we can discuss custom intergrations!

No, unfortunately the True View 635/640 3DIS units are not available under our subscription program.

Yes. The process is as follows:

• Contact your GeoCue sales representative to purchase the upgrade

• Ship your True View 635 to our Huntsville, Alabama USA office

• We will install the components necessary to upgrade the unit to include the external IMU-90 of the True View 640. This includes the addition of an internal interface board, the IMU-90 and cabling.

• We will fly a calibration flight and recalibrate your scanner

• We then ship the system back to you

For any airborne sensor, flying height is a compromise between resolution/accuracy and efficiency. In most cases, the lower you can fly, the higher will be the resolution and accuracy of the data. We will be creating a separate white paper on mission planning with the True View 600 series . A rough set of rules for the nadir above-ground level (AGL) is:

• Rough site work (volumetrics, 2’ contours) – 100 m

• General topo work, general purpose flights – 80 to 100 m

• Dense vegetation – 60 m with double coverage at right angles (e.g. fly the project N-S and repeat E-W)

• Transmission lines – 50 m from phases
