Aerial Photographs

HIG’s aerial photography products and services

HIG spends the time to provide our clients with high quality historical aerial photographs.  We have years of experience locating and obtaining aerial photography from a variety of public sources and private vendors, ensuring our clients receive great aerial photography sets and thorough custom aerial research services.

Historical Aerial Photographs
This is a set of aerial photographs compiled by our Researchers and designed to show a specific site over several decades.  HIG’s Historical Aerial Photographs are used extensively by environmental due diligence professionals, engineers, wetland professionals and others striving to determine the history of land use over time. They are also used to determine where to drill and sample during Phase II projects.

Highlights of HIG’s Historical Aerial Photographs:

  • Most of our aerial photographs have a scale of 1” = 500’ with a few at 1” = 800’. 
  • Each aerial photograph can show an area up to 5000’ x 7500’ or approximately 860 acres in size, dependent on the shape of the property.  Larger sites or irregular-shaped sites may require more aerial photographs at an additional charge.
  • We will provide 5 to 12 aerial photographs of different years typically ranging from the 1930s or 1940s to the near present.
  • Historical Aerial Photographs is offered a la carte and in all of our multi-product packages.
