When using GeoTagZ in combination with the AsteRx-m UAS receiver, it is now possible to obtain centimetre-level RTK ground precision from aerial survey. Using UAVs dramatically reduces time and cost in comparison to traditional ground survey.
Ground control points link aerial imagery to accurate location coordinates on the ground. However, setting out and surveying the position of ground control points is time consuming and expensive. In addition, ground surveys of mines, freshly reclaimed land and other geographically challenging locations may be hazardous if not impossible. GeoTagZ effectively removes the need for ground control points by updating the aerial photographs with high precision camera locations.
Smaller than a credit card, the AsteRx-m2 UAS and AsteRx-m2a UAS are Septentrio’s smallest and most efficient OEM receiver boards. Easy to integrate, they deliver precise multi-frequency, multi-constellation measurements for less than 1 W giving you more time in the air.
As well as logging GNSS data, the AsteRx-m2 UAS and AsteRx-m2a UAS record shutter-synchronized events from the onboard camera during aerial survey flights. It is these events which are then used by GeoTagZ to embed RTK-level camera locations in the images.
Whether using the updated photographs with embedded RTK-level positions or the position data in CSV format, the output of GeoTagZ provides direct input for image processing software.
- No need for ground control points
- No need for real-time RTK corrections
- GeoTagZ output provides direct input for image processing software
