Surveying

Drone technology is continually improving the way we do work and major efficiencies are being realized by organizations innovating by incorporating drones as tools. The surveying and mapping industry is one of many that are being revolutionized with the recent improvements in drone tech. Drastically increasing efficiencies of projects from the traditional time scale of days and weeks to hours, without sacrificing data quality. We understand that adopting new technology can be a daunting task, we are here to help you make informed decisions.

and PPK

SURVEYING VS. MAPPING

Mapping is creating a visual representation of geography and features.
A survey is also a map but with the ability to accurately measure distance and or distanced between two and three-dimensional points.
Both are related, however with different use cases and value.

WHAT IS RTK? PPK?

Real-Time Kinematic (RTK) with drones utilize a standalone "base station" that actively sends GPS data to the drone. Post Processing Kinematic (PPK) is an index of process performance which tells how well a system is meeting specifications . PPK calculations use actual sigma (sigma of the individuals), and shows how the system is actually running when compared to the specifications.

WHAT IS GCP?

Ground control points are marked points on the ground with known geographical location within your survey location. When used in photogrammetry, operators use lay large visible "targets/markers" to make them easy for the camera to capture. Then a survey grade GPS receiver is used to collect precise GPS coordinates of the centre of that target. A number of GCP's are needed to be spread throughout your survey area, depending on the size of the area.

GCP's can be used as "checkpoints" during data processing to verify and or correct the accuracy of projects. One stipulation of GCP's is the time required set and create them, which can decrease workflow efficiency. GCP's are not always necessary depending on the application the project output is being used in, for instances like creating marketing material or scouting.
