Setting up the requirements for a survey drone
We have already studied aerial surveys, their advantages, and the types of sensors that are used, so we won’t dive into the details here. Instead, we will jump into the main features a drone should have for surveys.
High-quality imaging sensors
High-resolution cameras or specialized sensors, such as multispectral or LiDAR for capturing detailed and accurate survey data, are the first requirement. We should consider the types of surveys for which different sensors are required, such as RGB cameras and LiDAR, and also consider their weight as this will impact the total all-up weight and performance of the drone.
GPS
We will need precise GPS capabilities to georeference survey data and ensure accurate mapping is required since geo-tagged images are the prime requirement for surveys. Also, a precise GPS is required for autonomous drone flight. A GPS with RTK capabilities would be a better option in the long run.
