Historic Aerial photography has many different uses. Because it provides data and a perspective that is otherwise elusive,
there are applications in academic research, resolving legal disputes, tracking genealogy, planning real estate development,
and much more. Government agencies, construction contractors, financial investors, legal professionals, and environmental
businesses use aerial photography quite extensively when performing:
|
|
|
» Environmental due diligence and site assessments
» Allocation of environmental liability
» Reclamation obligations
» Historical site documentation
» Vegetation growth tracking
» River and runoff trends
|

Historic Aerial Photos have been amassed by several government organizations such as the
United States Geologic
Survey (USGS), the Department
of Natural Resources (DNR), the
United States Department of Agriculture (USDA), as well as numerous private organizations. Historic Aerials.com has
revolutionized the storage and ease of access to these types of photographs with the use of
Geographic Information Systems (GIS).
GIS is a way to store data geo-spatially; that is, to reference data such as parcel boundaries, rivers & streams, contours,
even sewer lines to a point on the earth, and represent these in a dynamic three-dimensional model.

Formerly, these photographs were stored in large books and archived at federal, state, and county offices as well as
warehoused at private companies. Many times particular groups did not include the entire city or county, and often
these were flown at different altitudes and at irregular intervals. This lack of continuity is fertile ground for
the spatial database structure of GIS.

The original film or in some cases the photograph, are digitally scanned and stored on disk. The photos are then
manually orthorectified by the staff at HistoricAerials.com to ensure they
are overlaid accurately.

|
The photographs are next arranged into a mosaic to provide seamless alignment with one another.
|
|
|
 |
|
|
|
GIS stores these mosaics relationally in a database which allows access by association with a street address or by
some other type of data. The product is viewable from your terminal at any time of day, and may be viewed, printed,
or pasted into a report on demand.

|
By combining several years worth of data as separate layers in the same application, property sites maybe researched in
less time with greater efficiency. The result is a single online source that is more accessible to a user than having to
navigate the myriad of offices one would formerly need to visit.
