GIS Data 







Forensic Discovery and Expert Testimony:

Charles B. Pyke, Ph.D. and his Forensic Science Experts specialize in providing Forensic Discovery and Expert Witness Testimony, plus top Quality-Controlled, Expert-Analyzed, Graphed, Mapped, and Computer-Animated GIS-Capable Environmental Data, to the legal profession and the insurance industry, along with Court Trial Exhibits, including Power Point presentations.  We offer expert witness services to a wide variety of civil litigation, insurance claims, and criminal cases. 

Our fields of expertise include meteorology, hydrology, climatology, environmental science, geology, geotechnical engineering, entomology, and other science and engineering disciplines.

Some of our specific expert witness services include:

  • Black ice or dew -- on asphalt, concrete, grass, and other surfaces * / sun glare / weather conditions / meteorology / haze / sun angle, sunset, sunrise, civil twilight, cloud cover, moonrise, moonset, moon phase, and lunar illumination. *Timothy E. Wright, M.Sc. of The Forensic Science Experts is THE foremost expert on the topic of ice and dew -- or lack thereof -- on asphalt, concrete, grass, glass, metal, and other surfaces.

  • Evaporation / evapotranspiration / sublimation / melting  from reservoirs, lakes (liquid or frozen), farmland (dry, wet, or snow-covered), crops, forests, athletic fields, lawns, tennis courts, swimming pools, roads, sidewalks, and parking lots (dry, wet, snow-covered, or icy),  rooftops, vehicles, and many other surfaces.

  • Heavy rain, strong wind, dense fog, severe blowing dust / sand, dust devils, snow, hail, lightning. 

  • Wind-blown pesticides, causing downwind crop damage or livestock loss.

  • Hydrology / floods / mudflows, water intrusion, water regulation, plus groundwater issues, and avalanches. 

  • Environmental science, including soil and water sampling and testing for toxic chemicals, algae, oil, pesticides, sewage, and other foreign substances.

  • Geology / geotechnical engineering / soil strength / seismology.

  • Entomology / termites, bedbugs, bees, cockroaches, spiders, fleas, mosquitoes, flies, larvae, rodents / pest control.

  • Other sciences and engineering.
