Photo Science serves growing LiDAR market with Leica airborne laser scanner, fleet of aircraft
NORCROSS, Ga., 19 March 2012. Officials at Photo Science, a geospatial services firm in Lexington, K.Y., have purchased a Leica ALS70-HP airborne laser scanner from Leica Geosystems Inc. Photo Science, now with a total of four Leica LiDAR systems owned, has also contracted Leica to upgrade one of its existing ALS60 sensors later this year.
One of the largest precision aerial acquisition operations in the U.S., Photo Science owns four Leica LiDAR sensors and three Z/I Imaging large-format DMC digital mapping cameras, as well as operates a fleet of 10 single- and twin-engine aircraft deployed nationally.
The Leica ALS70 is an airborne laser scanner with an effective 500 kHz pulse rate capability designed specifically for high-density point collection in diverse environments, which can reduce flying time up to 60 percent. The ALS70’s Point Density Multiplier technology allows for a quantum increase in measurement and scan rates over previous capabilities. The Leica ALS70-HP version purchased by Photo Science was developed for general-purpose mapping over a wide variety of terrain at different flying altitudes.
The markets for LiDAR data are maturing in two ways: First, existing applications for digital elevation data are requiring an increase in point density per square meter, which the powerful ALS70 can accommodate; second, the demand for accurate LiDAR data is now coming from new markets, including vegetation analysis and utility transmission line mapping, that require bare-earth returns in narrow corridors.
“Many LiDAR sensors on the market are designed with one application in mind, but the ALS70-HP is a true multi-purpose laser scanner developed to meet the needs of many markets,” says Jean Gardiner, general manager of Leica Geospatial Solutions. “And the ALS70-HP can be upgraded to the HA version for firms that need to perform high-altitude LiDAR collection.”
