Eugene Avery, a pioneer in the education of scientists in the use of aerial photographs and other remote sensing methods in their field, makes a distinction between photo reading and photo interpretation in his textbook Fundamentals of Remote Sensing and Airphoto Interpretation available at Amazon:
"Photo interpretation is defined as the process of identifying objects or conditions in aerial photographs and determining their meaning or significance. This process should not be confused with photo reading, which is concerned with only identifications. As such, photo interpretation is both reading the lines and reading in between the lines."
Ebert and Associates has developed an approach to environmental sites which involves photointerpretation (we spell it as one word!), digital mapping, and knowledge of human industrial behavior to develop defensible and strategic legal arguments concerning liability for site contamination.
We also know that finding the correct photographs, especially aerial photographs, is an important as developing legal arguments based on map information. We have 25 years of experience and skill in obtaining and processing photographs.
