Over the years AERO-METRIC's Alaska clients have counted on high quality services using Optech sensors. With increased data collection rates and accuracy, Optech's new ALTM 3100EA system (EA stands for Enhanced Accuracy) is regarded as the best model available today. Both horizontal and vertical accuracies are more than twice as good as as the 30/70 system. The new system will produce horizontal accuracies of 1/5500 of the altitude compared with 1/2000 from the 30/70. Vertical accuracies of less than 5cm are possible at 500 meters above ground, ranging to less than 20cm at 3 kilometers altitude.
LIDAR technology offers one of the most accurate, expedient and cost-effective ways to capture wide-area elevation information to produce highly detailed Digital Elevation Models (DEMs). |

LIDAR data sets contain vast amounts of information. Buildings, trees and power lines are individually discernible features. This data is digital and is directly processed to produce detailed bare earth DEMs at vertical accuracies of 0.15 meters to 1 meter. Derived products include contour maps, slope/aspect, three-dimensional topographic images, virtual reality visualizations and more.
LIDAR data can be seamlessly integrated with other data sets, including orthophotos, multispectral, hyperspectral and panchromatic imagery. LIDAR is combined with Geographic Information System (GIS) data and other surveying information to generate complex geomorphic-structure mapping products, building renderings, advanced three dimensional modeling/earthworks and many more high quality mapping products. |
Due to the growing need for precision DEM data, AERO-METRIC Anchorage is developing an archive of elevation data to complement our extensive historical and current film library. Over one billion data points covering more than 500,000 acres are included in our DEM archive.
Let AERO-METRIC help you plan your next LIDAR project and share with you the value of this exciting technology. |
