About this calculator
A drone camera's ground footprint depends on flight altitude and the camera's angular field of view (FOV): at a given height, a wider FOV or a higher altitude both capture more ground per photo. The footprint dimensions follow ground width = 2 × altitude × tan(HFOV/2) and the equivalent formula for ground height using the vertical FOV, with coverage area as their product.
Survey and mapping pilots use this to plan flight altitude for a required ground sample distance and to calculate the flight-line spacing needed for a target image overlap — critical for stitching aerial photos into an accurate orthomosaic.
