Combining Intergraph's Z/I Imaging Digital Mapping Camera and Optech's Airborne Laser Terrain Mapper speeds the delivery of photogrammetric products.

Intergraph Mapping and Geospatial Solutions and Optech Incorporated announced that they have entered into a strategic alliance to jointly market and further develop airborne flight management and data acquisition systems. Under the terms of the agreement, both companies will sell a bundled solution consisting of Optech's Airborne Laser Terrain Mapper (ALTM) and Intergraph's Z/I Imaging Digital Mapping Camera (DMC) at a special bundled price. Commercial photogrammetry, surveying, civil engineering and mapping firms can now realize cost savings when purchasing two of the best-in-breed data acquisition technologies. Also, users will gain the efficiencies of combined lidar and digital data collection to speed the generation of Digital Terrain Models (DTMs) as input into orthophoto production. Additionally, the two companies will cooperate on the development of flight systems that more tightly integrate LiDAR and large-format digital camera technology.

The Z/I Imaging DMC offers a rigid frame and fixed-pixel geometry that delivers high-quality imagery with proven ground resolution down to 1 1/2 inches per pixel for input into a completely digital workflow. Another design feature of the DMC is its ability to collect frame-based four-band multi-spectral imagery simultaneously with panchromatic data on a single pass of the flight line. This allows three separate end products - black and white, natural color and false-color infrared - to be generated from a single airborne data set.

Optech's ALTM offers area coverage rates as high as 100 kHz at 1,100 m altitude, producing elevation data of unparalleled density and unprecedented low cost per posting. ALTM is a complete end-to-end survey solution that includes Optech's ALTM-NAV Flight Management Software for survey planning, and REALM Survey Suite, Optech's fully integrated data processing software. Additional features include: adjustable scan frequency, scan angle, and pulse repetition frequency; variable beam divergence; roll compensation; laser intensity for highly detailed images; and full technical support anywhere in the world.
