Images are scaled using USGS topographical maps or images are geo-coded and
rectified using DOQQS. DOQQs are produced by the Texas Orthoimagery Program
and are acturate to 1 meter. Images can be printed
on photographic paper and or copied to CD, DVD or an FTP site for delivery
to the customer.
The size of each image is 9" X 9" if from film. The footprint of each
digital image is 4.5" x 6" at 1200 dpi. The negative scale of each image is
determined by the altitude flown. The negative scale can then be enlarged to
5 times from film and 8 times if digital to reach the desired print scale.
All new imagery is shot in digital format only.

Garland, TX
Accident sites are normally shot at a low altitude,
marks are painted on the road at 100' intervals. This allows a more
acurate scale to be set in the darkroom The negative scale of this
image was shot at 1"=150'. The printed scale was 1"=30'. |

negative scale of this image was 1"=1000'.

Airline @ Cimarron Blvd
The negative scale of this image is 1"=2000'. The

measurement. The ground distance between the two roads is 1 mile as
measured on the USGS topographical map.
