Since the launch of Ikonos in 1999, remote sensing technology has exploded, and multispectral and panchromatic imagery has become more and more sophisticated and complex.
Currently, GeoEye-1 is the world's highest spatial resolution (41-cm panchromatic and 1.65-meter multispectral) commercial earth-imaging satellite. It provides 4 multispectral bands—red, green, blue and near infrared. GeoEye-2 is scheduled to launch in early 2013 and has a planned spatial resolution of 25-cm.
AeroMetric has kept pace with the changes and has developed a great deal of expertise in remote sensing technology. This includes a deep knowledge of the choices to be made in any remote sensing assignment. Expertise begins to tell when things get complicated and there are dozens of competing technologies and methodologies to choose from. We have the in-house experience, a wide variety of sensing equipment, as well as alliances in the satellite imagery and analytical industries to help you find the right path to your remote sensing destination.
Airborne and Satellite Solution Examples
- Lidar can measure the shape of the earth's surface from the treetops to the ground, resulting in maps with exceptional detail.
- Radar can detail large areas – and when used for monitoring it can measure millimeter scale changes, distinguish subtle variations in ground cover, and even detect regional movement after an earthquake.
- Optical sensors – measuring the portion of the spectrum we can see – can subdivide the visible spectrum to detect pollution, mineralization, water depth, impermeable surfaces, the impact of flooding, and various hazards.
- Multispectral sensors detect information beyond the visible wavelengths. For example, near infrared is often used for detecting and classifying vegetation type and density. Mid-infrared can detect water depth, soil moisture content, forest fires, and even soil types such as silicates and clays. Applications include geologic and environmental documentation and analysis. Maps showing land cover and land use can be prepared. Multispectral imaging can also be used to prospect for minerals, search for oil fields, monitor forests, and study plants and farms.
- Thermal infrared uses emitted radiation and can be used for night studies, for detecting fires and hot spots, and thermal differences in water currents.
