including geographic information in the metadata of a photo, so those processing the images can more easily determine the precise position of points in the image. Microdrones offers a free tool called mdGeotager to help users simplify this process.
a mount that holds the sensor on the aircraft and pivots around a single axis, ensuring the sensor is always pointing at the same angle, regardless of the orientation angle of the drone. Some mdMapper packages feature our custom brushless gimbal, which helps to improve data accuracy.
an acronym for Global Navigation Satellite System, GNSS is an autonomous positioning system with global coverage, including GPS, GLONASS, Galileo, Beidou, and other regional satellite positioning systems around the world.
Ground Control Points (GCPs)
points positioned on the surface of the Earth in known locations and used to georeference collected data. Surveyors and other geospatial professionals often install many ground control points for large projects to ensure accuracy. With a direct georeferencing UAV mapping solution, no ground control points are necessary.
