LH Systems released PRO600 v4.3 for photogrammetric data capture. New features include an overhaul to its multi-line tools, enhancements to building squaring, new centerline generation and line thinning tools, and better management of multiple feature coding. Also added to the PRO600 is the PRODTM, a semi-automatic terrain measurement procedure that supplements automatic image correlation with manual measurement. Another new tool allows 2D design files to be easily converted to 3D by overlay on an existing terrain surface. (LH Systems LLC, San Diego, Calif.)
