Since DJI aircraft populate the image geotags with using the barometric altimeter (relative to the home point) and not the GPS altitude (absolute above sea level), Map Pilot automatically records an image at the takeoff point after the start of every mapping flight.
Include this image in your upload to Maps Made Easy for proper elevation offset calculation and elevation readings.
NOTE: Due to how Maps Made Easy uses ground reference images to correct for the use of the barometric altimeter in its elevation processing, it is highly recommended to take off from an area of undisturbed ground. Taking off from man-made structures or in areas of heavily modified earth will not correspond well to the reference values we get from the NASA SRTM elevation data and will result in elevation offsets.
Important for Multiple Takeoff Locations: If you are taking off from multiple takeoff locations, DO NOT upload the ground reference images with your data. We only use one ground reference image for the altitude corrections and if your reference images were taken from multiple elevations there is no way to control which on gets used. Uploading ground reference images from multiple elevations will likely do more harm than good.
