Based in Australia, Nearmap offers high-resolution aerial imagery with protection across the United States. They supply vertical, indirect, in addition to 3D and AI project mapping capabilities. Getmapping has two vertical aerial information merchandise obtainable in 12.5 cm and 25 cm decision, simply accessible on the UP42 market. As an added bonus, Getmapping can also present bespoke Aerial Surveys where off-the-shelf footage just isn't available, at an reasonably priced worth.
EarthExplorer has an ‘Order Scene’ icon () on the results page for pictures which are obtainable for photogrammetric quality scanning.
