When it comes to aerial mapping applications, RGB cameras are the go-to choice for capturing sharp images and fine details. To achieve the highest quality results, it's important to select a camera with a higher resolution and larger sensor. This will increase the GSD (Ground Sampling Distance) and allow you to fly higher while still achieving the same level of quality. If there are any forms of interference closer to the ground, this should be taken into account when selecting a camera model for drone studies and inspections. When buying a camera for drone surveys, there are several key features to consider.
First and foremost, pay attention to the camera specifications that directly affect the GSD. Other important features include the camera's resolution, sensor size, focal length, and frame rate.
