Based in Australia, Nearmap presents high-resolution aerial imagery with coverage throughout the United States. They offer vertical, oblique, in addition to 3D and AI project mapping capabilities. Getmapping has two vertical aerial knowledge products available in 12.5 cm and 25 cm resolution, easily accessible on the UP42 marketplace. As an added bonus, Getmapping can also provide bespoke Aerial Surveys where off-the-shelf footage just isn't available, at an affordable value.
EarthExplorer has an ‘Order Scene’ icon () on the results web page for pictures which may be out there for photogrammetric high quality scanning. Options for prime decision BW pictures fotografie embody 25 microns , 14 microns , or 7 microns . Options for high resolution shade pictures embody 25 microns or 14 microns . On-demand film scans for Aerial Photography Single Frame Records usually are not archived within the USGS EROS database and aren't obtainable for obtain via EarthExplorer.

Another methodology used to determine the scale of a photograph is to search out the ratio between the digicam's focal size and the airplane's altitude above the ground being photographed. For all different larger decision imagery, an order will must be placed to scan the movie at $30.00 per frame.
