Historical Aerials For Your Research
If you need to see a site over a span of decades, our sets of historical aerial photographs can provide the most complete picture available. HIG has one of the largest in-house collections of historical aerial imagery in the United States.
Historical aerials are often used by environmental consultants, engineers, planners, wetlands specialists and history buffs. They can also be used to determine where to collect soil and groundwater samples during a Phase II Environmental Site Assessment.
What you can expect:
- A set of aerial photographs with dates usually ranging from the 1930s or 1940s to the near present.
- Most of our aerial photographs have a scale of 1” = 500’ with a few at 1” = 800’.
- High-resolution photography used whenever possible to help provide clear, crisp images.
Report-Ready Historical Aerials (PDF)
These photographs are easy to add to your existing reports or import using report writing software.
- Photographs show an area up to 5000’ x 7500’ or approximately 860 acres in size, dependent on the shape of the property.
- Each photograph is presented in a title block that includes your project information, the scale and date of the image.
- Your site is centered in the photographs to provide the best views of the site and surrounding properties.
GIS-Ready Aerials
Do you need more functionality from your aerials, especially for your corridor or large area projects? We can provide georeferenced historical and modern photography for any size project in the United States.
- Images are approximately one (1) meter resolution in most cases, and are compatible with GIS and CAD software.
- We use at least three ground control points per image over a modern orthophoto base map to provide cost-effective georeferenced accuracy suitable for general analysis.
- Photography is referenced to your local UTM Zone, in feet or meters.
We’re happy to discuss your project needs so we can provide custom specifications if needed for your project.
