Abstract: In the Geotechnical world, it is well known that "IN DISASTER THERE IS PROFIT", and the Montecito, CA. debris flows are one of the more recent examples. Major Debris Flows that are related to one of the largest Wild Fires in State history. Early detailed Geotechnical visual documentation is the key to cost effective marketing, project acquisition, preliminary field investigations, and long term predictions of future related damages. Visual images are still the most useful, most accurate, and most reliable form of data, and evidence in all aspects of hazard investigations, and legal procedures.

Geotechnical firms planning for events like the Montecito Debris Flows should start well in advance of these types of events, and the firms should be ready to start full documentation protocols upon occurrence, to improve their chances of acquiring work on such projects. The visual documentation should be in Stereo, and GPS based, for ease of use in GIS software's. This will substantially reduce short and long term investigation cost, and expand uses of the imagery in related work areas, such as litigation, which is highly probable in Geotechnical Disaster events.

Firms that do this type of investigation work in the long term face many unseen hazards and risk, not all of which are geotechnical. Many are legal, and some of those risk are directly related to Public Corruption that is mostly hidden from the public, and operated for the financial advantage of Law Enforcement Public Agencies, and Insurance Companies.

2D and 3D images flown immediately after the Debris Flow and Wild Fire events will be utilized to highlight various aspects of damage documentation, investigation enhancements, and prediction of future threats. If you have Anaglyph 3D (Red/Blue filter glasses) bring them along, if not I will bring a stack of glasses for use by attendees. Various FREE and easily obtainable image viewing and GIS software programs will be utilized for this presentation.

Mr. Woodrow L. Higdon (Woody) has been an AEG, SCGS, and SDAG member since the mid 1970's. Woody has degrees in Marine Geology ‐ Oceanography from Cypress College, a Geology degree from Cal State University Long Beach, and worked for Leighton and Associates as a staff geologist from 1975 thru 1979.

In 1979 Woody left L&A to concentrate on developing and expanding Geo-Tech Imagery, which has specialized in Land Use Imagery for the past thirty 38 plus years. He did post graduate studies in remote sensing imagery through Harvard University in 1981. Woody plans, generates, analyzes, and reproduces all types of 2D and 3D images, based on Geotechnical issues, (aerial, ground, and underwater in both photography and video), for all aspects of land use. Starting from pre-acquisition, through Geotechnical investigations, grading and construction, litigation, and marketing, to final sale documentation.

GTI has over 250,000 frames (+) of standard color, false color infrared, black and white, and side scan radar imagery, in its GIS cataloged image library, covering 1928 to the present. One of the few photo libraries in the world with 35+ years of Stereo aerial vertical, aerial oblique, and ground photography. Woody has sold GIS Software and Data, consulted, trained, and utilized GIS software since the 1960's.

Woody is a former Recon Marine with specialized training in Airphoto Interpretation, Combat Photography, and Underwater Photography from Naval Diving Schools. Upon discharge from the Marines, he became a police officer for the cities of Santa Ana and Garden Grove, California, which included forensic photography, as part of his patrol duties. GTI's Photography and Video support skills include Naval Diving Schools certifications, PADI Diving Instructor Certification, and Helicopter Pilot Certifications, with more than 40 years of experience.

GTI's in-house support capabilities include high resolution digital image scanning, digital image editing, GIS encoding and image rectification, non-linear real time digital video editing, 3D computer based image analysis, and high resolution large and small format print reproduction.
