Leica Geosystems' relationship with Digital Aerial Solutions (DAS) was further strengthened by DAS' purchase of Leica Geosystems' ALS60 airborne LiDAR scanner, the company's third-generation LiDAR (light detection and ranging) system. Already an avid Leica ADS40 digital airborne user, the Leica ALS60 technology complements DAS' existing aerial imaging capabilities to provide an efficient and cost-effective means to acquire accurate, terrain elevation data and create high-resolution digital terrain models (DTMs), digital elevation models (DEMs) and topographical map products for a variety of project applications. With the Leica ALS60's modular platform, DAS will be able to integrate additional airborne sensors to offer concurrent, high quality airborne images from its LiDAR surveys, providing clients with an additional visual perspective of their survey area.
