Criminal investigation often takes place hurriedly and under (to say the least) less than favorable circumstances. It's 3 o'clock ing the morning and raining; officials or family want to remove the body; and even seasoned personnel are tired and disturbed by what they see. Crime scene investigators are trained to make accurate maps, but it is impossible to determine completely what sort of evidence will become important when legal proceedings take place,often years later. The many photographs that forensic investigators are also taught to take contain information that isn't even noticed at the scene: bite marks, subtle blood spatter patterns, and tiny objects on the floor. Ebert & Associates, Inc., had been using image processing, digital photogrammetric and other forensic imaging and mapping techniques to extract crucial forensic information and make maps and measurements from photographs and other imaged data (for instance, video, which is often of less-than-ideal quality) to aid in criminal investigations, prosecution, and defense.
