Dave Ruiz has 17 years of experience in aerial photo interpretation in both military intelligence and civilian mapping. He has served as an expert in criminal and civil cases and specializes in real estate issues.
Some of his former clients:
Chevron Department of Justice Gilchrist & Rutter Rossi, Hamerslough, Reischl & Chuck Ellis Geospatial Inc. Law Office of Chavez & Gertler
As an Imagery Analyst, Mr. Ruiz has conducted analysis and prepared technical reports for clients involved in legal matters. He has testified as an Expert Witness using his technical training and reputation to solidify his clients' positions in legal matters where imagery is the critical factor.
Testimonial -I first met Dave Ruiz when he appeared at trial as a witness for the opposing side. He made a devastatingly good witness-- honest, articulate and forthright. His depth of expertise was beyond question. As a result, we ended up calling Mr. Ruiz back to the witness stand in our case-in-chief, giving meaning to the timeworn expression, "If you can't beat them, join them." Next time I need any imagery consulting services for any matters in litigation, I hope to be fortunate enough to be the first one to hire Mr. Ruiz as an expert, because I would not want to encounter him again in the courtroom as the unfortunate lawyer assigned the task of cross-examining him.

As an Army Imagery Analyst 96D, Sgt. Ruiz completed advanced training in imagery interpretation. His duty stations included theater wide intelligence (J2) in Korea and the National Ground Intelligence Center (NGIC) in Washington D.C. While assigned at NGIC, Sgt. Ruiz worked closely with other agencies such as the Defense Intelligence Agency (DIA) and National Imagery and Mapping Agency (NIMA). Duties required accurate and timely intelligence of national interest and are the basis of his current success.
After leaving the United States Army, Mr. Ruiz was recruited to work for HJW Federal, where he was the Production Supervisor for NIMA products under the NIMA Omnibus contract. Upon the termination of the contract Mr. Ruiz was promoted to the Image Library Manager, Operations Manager, and Flight Operations Manager. He has experience with traditional mapping cameras, LiDAR systems, and the Vexcel Digital mapping camera, digital photo editing, photo enlargements, and lab operations.
These images were taken at 6000' ASl from a fixed wing plane equipped with a large format aerial mapping camera. The original aerial photo was captured at 1:12000 scale photo which displays a 1" = 1000'. From this photograph it is possible to enlarge the photo to as much as 1" = 20', however depending on what your requirements are, it may not be wise or required to do so.

Here we see two examples of possible neighborhood nuisance's. The top photo shows (in the red circle) two radio antennas used for Amateur radio transmissions. Powerful signals can cause disruption to other radio signals such as AM/FM radios. Historical aerial photographs have been used to establish the location of such nuisances and when they first appeared on the property.
The bottom photo reveals a neglected, untreated pool with stagnate water, (in a red box). Pools in this condition have been know to bred mosquitoes that could carry disease, which are passed on to birds, animals and humans. Local governments have used aerial photos such as this to identify negligent homeowners.
Historical and current aerial photos are used to identify and prove easements issues, environmental issues, construction progress, and can be used to measure area in crime or accidents scenes. As a trained professional in aerial photographic interpretation I have helped clients strengthen their legal position on a variety of issues with the use of aerial photos.
