DDIS specializes in aerial photography, visual impact studies, viewshed surveys, and balloon tests, for marketing, zoning, site planning, and architectural design. Due to our extensive experience and specialized aircraft (surveillance aerostats and drones), we are able to access highly restricted, urban airspace, when others cannot. We have captured aerial photography and provided aerial viewshed studies for many of the tallest buildings across the US. Our moored balloon is often flying in Washington, DC, and New York City. if you see an aerostat over the city, it’s probably us.

*DDIS services come with analysis overlays, height data, image documentation, and visual impact recommendations.
