The Digital Imaging Answer for Aerial Survey and Remote Sensing Applications

First introduced in 2002, the Applanix Digital Sensor System (DSS™) has become the industry’s leading medium-format digital aerial camera system integrated with a complete Direct Georeferencing workflow and flight management technology. As a mapping-quality alternative to large-format digital cameras, DSS offers important advantages including the ability to produce ultra-fast results that are certified as mapping-grade by the USGS. Light weight and ruggedized, DSS can be integrated with different sensors to fulfill special applications. Some options include a DualCam for simultaneous RGB/NIR collections, and a Riegl LMS-Q560 LIDAR option for high accuracy corridor mapping. For high altitude LIDAR applications, the DSS is available as an OEM option on the Optech ALTM LIDAR systems. The DSS is a powerful solution for applications such as Earthworks Monitoring, Power Utility Mapping, Roads and Highway Mapping, Photogrammetric Mapping, and Rapid Response.

DSS has now become the system of choice for agencies engaged in rapid response. RapidOrthoTM images can be produced using the logged real-time POS AV solution and an existing or extracted DEM for delivery to first responders within hours of landing. Recently DSS has been put to the test in a number of critical emergency response situations, including:

Response to Hurricane Ike: NOAA collected post storm imagery in response to Hurricane Ike using both the Applanix 439 DSS and an Applanix 439 Dual Cam DSS. Over 5,500 color aerial images captured the hardest hit areas in Texas and Louisiana after Ike made landfall. These images, made available to emergency personnel and the public on the NOAA/NGS web site within 24 hours of acquisition (, were georeferenced from post-processed POS AV GPS-Aided Inertial Navigation Solution parameters, and orthorectified using Applanix’s RapidOrtho software. “We now have a long standing relationship with Applanix and their technology, and a successful track record of using and developing this technology for our day to day operations and for emergency requirements, such as with Hurricane Ike,” said Michael L. Aslaksen Jr., Chief of the Remote Sensing Division at NOAA’s National Geodetic Survey.

New Brunswick Flood of 2008: In the spring of 2008 the Canadian province of New Brunswick and the US state of Maine suffered from some of the worst flooding seen in over 25 years. The Government of New Brunswick contacted Leading Edge Geomatics (LEG) with a request for aerial survey support to assist in their flood relief efforts. Using the Applanix DSS 322 and POSPac software, LEG acquired over 7000 square kilometers, processing more than 5,500 orthophotos. Collected at 50cm resolution, this imagery assisted the government in immediately providing aid to flood-affected residents and determining damage to infrastructure and property. “LEG provided us with 30-50 cm orthophotos within a few days and a fully-processed continuous database within 2 months,” said Ernest MacGillivray, Director of Emergency Measures and Public Safety for the province of New Brunswick. “The instruction, education, and simplified workflows from Applanix enabled us to succeed in this mission,” said Sammy Sampson, Director at LEG. “The equipment itself is rock solid – accurate and reliable. And in addition the know-how and expertise provided to us by the Applanix customer support team was unbelievable.”
