ER-2 Sample Data And Film Products
Airborne Ocean Color Imager
Aquatic ecosystems research is supported with the Airborne Ocean Color Imager (AOCI) which is another Daedalus multispectral scanner configuration. An outgrowth of the Coastal Zone Color Scanner, it has spectral bands designed for the mapping of chlorophyll, suspended sediments and water surface temperature. The AOCI provides ten-bit digitization of eight bands of the visible spectrum with two additional bands of eight-bit digitization in the near and thermal infrared portions of the spectrum.
Thematic Mapper Simulator
A widely used digital multispectral scanner flown aboard the ER-2 is the Daedalus Thematic Mapper Simulator (TMS). Simulating the performance of the Thematic Mappers (TM) orbiting on Landsat 4 and 5 satellites, it replicates the spatial and spectral characteristics of the seven bands of digital data acquired by the Thematic Mapper. Four additional spectral bands are also acquired by the TMS while TM band 6 (thermal data) is acquired at full resolution in two channels in low and high gain settings. The TMS has provided data for land use and land cover analysis, forestry applications, geologic studies and disaster assessments.
MODIS Airborne Simulator
The MODIS Airborne Simulator (MAS) is a modified Daedalus multispectral scanner configured to approximate the Moderate-Resolution Imaging Spectrometer (MODIS), an Earth Observing System (EOS) imaging spectrometer scheduled for orbit in the late 1990s. MODIS is designed to acquire digital imagery for measuring earth biological and physical processes and atmospheric properties. MAS records fifty channels of sixteen bit data in the visible, near infrared, mid-infrared and thermal portions of the spectrum.
High resolution aerial photography is collected during earth imagery acquisition missions. Multiple camera systems may be flown with a variety of film types acquiring photography at varying scales and resolutions.
RC-10 Mapping Cameras
Wild Heerbrugg RC-10 Mapping Cameras with a 9 x 9 inch image format are flown on virtually every ER-2 earth imaging mission.
