Field photos documenting the first deployment of mono-chrome laser-radar (Lidar) by Dr. Grossman in 1999. Initially released in 1998 by the Cyra Corporation, this new 3D recording system was deployed by Dr. Grossman, in conjunction with advanced computerized single-camera photogrammetry, to capture a high resolution 3D record of this emergency "discovery under construction", a last-minute find by the Hartgen archaeological team, that proved to be the densely constructed wooden colonial bulkheads and docks of 18th and 19th century Albany.
The single-camera Rolleimetric photogrammetry was initially adapted for archaeologyical emergency rescue and documentation by the author to record contaminated archaeological discoveries in federal "Superfund" remediation, or clean-up, programs. The flat-field metric camera has a 90 degree flat-field lens that allowed flexibility (+/- 20 degrees) bt trhw HAZMAT-suited archaeologist, and the ability to digitize and extract real-world coordinates from the computer integration of multiple "georeferenced" metric photos of a feature or area (See West Point Foundry for initial deployment; Grossman 2004, 2007a for details).
The initial release of the, still-under-development, laser-radar scanning system (still in their wooden proto-type cases), coupled with the density and size of the 3D data scan files, overwhelmed the processing "point-reduction" and of image creation capabilities of this first generation of software. Its utility as an archaeological tool was also limited by the monochrome "false color" results that lacked color information required by current Department of Interior guidelines and standards for the proper documentation of endangered historic monuments and archaeological sites (Photogrammetry, Lidar and Applied Technology Mitigation Plan by Joel W. Grossman, Ph.D. All photos courtesy of Hartgen Archaeological Associates, Inc. Albany, New York).
True-color terrestrial laser-radar, with integrated color data for each coordinate measured, was not released until the summer of 2003 and was initially deployed by Dr. Grossman in North American archaeology to document the flood damaged Furnace Falls Dam/Morris Canal historic district under deep-winter conditions in January 2004 (see Stanhope 2002 and 2004; Grossman 2002, 2004 & 2007a).
