Eagle Mapping Ltd., a North American digital airborne mapping company, is now using the new Riegl LMS-Q1560 airborne laser scanner system. Designed to capture ultra-wide swaths and complex environments, the high-performance Riegl LiDAR will enable Eagle Mapping to expand into new markets including large-area, forestry and urban mapping applications for governments and first-nation organizations.
“The Riegl LMS-Q1560 is a powerful laser scanner developed to acquire data over large geographic areas at high altitudes,” said James Hume, Eagle Mapping President. “This will allow us to map expansive cities, counties and tribal lands quickly and cost effectively.”
Riegl designed the powerful dual-channel LMS-Q1560 laser scanner with integrated medium-format camera for a variety of airborne mapping projects with an emphasis on wide-swath coverage. With a 58-degree field of view, the laser can be operated at a maximum pulse repetition rate of 800 kHz capable of measuring 530,000 points per second on the ground from an altitude up to 15,500 feet AGL.
“The Riegl LMS-Q1560 is the most cost-competitive airborne laser scanner on the market today,” said Hume. “We can fly at a higher altitude and collect a denser spacing of elevation data than any other LiDAR system out there.”
In addition, the Riegl LMS-Q1560 has a forward-and-look capability which, when combined with its wide field of view, enables the device to capture data from multiple angles effectively and accurately at an extremely high point density. The sensor also utilizes Multiple-Time-Around processing, echo digitization and waveform analysis to simultaneously track more than 10 pulses in the air.
This means the LiDAR can collect tightly spaced elevation points even in complex environments. Examples are built-up city centers with a variety of buildings and vertical structures, as well as extremely rugged mountain terrain where elevations change dramatically and abruptly.
“Whether working in the mountains of British Columbia or over a densely developed urban center, we will capture accurate elevation points between soaring peaks as efficiently as we do between high-rise office buildings,” added Hume. “And regardless of the terrain, we’ll collect more data in a day and finish jobs faster than we could before.”
Over nearly three decades, Eagle Mapping has built its reputation on finding more accurate and affordable mapping technologies. Focusing primarily on the global mining industry, the Vancouver firm was among the first to deploy airborne LiDAR technology for mapping. More recently, the Canadian firm configured a high-density, narrow-swath Riegl VQ-580 LiDAR with a DiMAC medium-format camera on a single aircraft to simultaneously collect elevation and image data for efficient mapping of pipeline and transmission line corridors.
“As we expand into urban and large-area projects for government clients, we will continue to support our extensive client base in the international mining and corridor mapping markets,” said Rodney Cope, vice president of sales and marketing.
Eagle Mapping operates a Cessna 206 and Piper Navajo aircraft based in British Columbia. The Navajo carries the new Riegl LMSQ1560, and the Cessna is equipped with the Riegl VQ-580 LiDAR and DiMAC digital camera. The firm maintains field offices in Bellingham, Washington, USA, and Medellin, Colombia, in South America.
