We operate FAA-certified Learjet-36 platforms for custom airborne data collection. Our aircraft operate as C4-ISR platforms and fly at high speed and high altitude. We have wide-area collection capabilities and use IFSAR remote sensing techniques to provide 3D positioning and imaging using high-accuracy imaging radar. We have decades of experience deploying this multi-sensor technology in over 40 countries worldwide.
This multi-sensor approach provides key tactical advantages for deployment, unrestricted by daylight, weather, cloud cover or foliage. We augment our proprietary multi-sensor IFSAR data and LiDAR with satellite imagery for unprecedented situational awareness. Custom collection options are also available to suit your needs.

Intermap's commercial airborne collection features high-altitude multi-frequency ISR, triple-canopy foliage penetration, high-resolution global elevation data, and analytics platform for exploitation and dissemination of data
Intermap collected airborne SAR data over Napa Valley, USA. The image slider shows 1.5 m resolution X-band orthorectified SAR imagery from a satellite sensor (left) and Intermap’s airborne sensor (right). Airborne SAR contains more detail and contrast due to the higher signal-to-noise ratio.
Alaska Mapping Initiative
Intermap was responsible for delivery of over 1.5 million km2 of reflective surface and bare-earth elevation content and orthorectified imagery to Alaska stakeholders. We also provided custom content derived from the baseline elevation data including slope, contour layers and hydrology information.
Alaska IFSAR acquisition supports the broader national 3D Elevation Program. For more information, visit Alaska Mapping Initiative.
Peninsular Malaysia Collection
Intermap provided simultaneous collection of high-resolution X-band and P-band imagery over Peninsular Malaysia, an area of approximately 130,000 km2, in just 35 days. We also conducted hybrid DEM fusion services for 30,000 km2 LiDAR data, and over 24,000 km2 of satellite SAR data.
Philippines National Mapping Program
Intermap assisted in the creation of a framework for the Philippines transition to a digital economy and to support the Philippines National Mapping Program at 1:10,000 scale. Approximately 7,100 islands totaling 300,000 km2 were captured in 89 days (including the discovery of ~400 new islands) using our airborne IFSAR platform, and all collected data was processed and manually edited to create hydro-enforced bare-earth models.

Dominica NEXTMap One LiDAR Fusion
In March 2020, Intermap teamed with McElhanney Consulting Services Ltd. to provide NEXTMap One data to fill in areas on the island where LiDAR data was difficult to collect. This initiative is part of the Disaster Vulnerability Reduction Project set out by the Government of Dominica through the Ministry of Health and Environment.
Intermap utilized its multi-sensor technology to mitigate cloud cover and fill in the 235 square kilometers of missing LiDAR data. Intermap’s NEXTMap One approach, combined with DEM fusion technology, was required to provide a seamless, high-quality dataset for McElhanney. The final island-wide dataset is critical for effectively planning and managing flood control, drainage, land stability, and potential landslide areas.
