CAMS provides calibrated data in a Landsat Thematic Mapper configuration. The CAMS sensor is flown onboard a LearJet by NASA Stennis Space Center and collects imagery in the visible, infrared and thermal infrared bands. The spatial resolution of the CAMS imagery varies depending upon the height of the aircraft, but is typically 3-7 m. Due to the high resolution of the imagery, the CAMS data is collected in flight strips which generally will require mosaicking to adequately cover a target area. CAMS imagery can be geocorrected using information from an onboard GPS navigational system.

The CAMS multispectral scanner includes two additional bands compared with Landsat TM, with an band in the Orange range and an additional band in the red/near infrared wavelength. The thermal band (9) of the CAMS is also an improvement over TM imagery, since it is acquired at the same spatial resolution of the other bands.

Benefits of CAMS for Wetland Mapping

In comparison to current multispectral satellites, CAMS offers increased spatial resolution which helps improve wetland mapping due to the small size of many marshes. CAMS also has increased spectral coverage which allows for better isolation of vegetation types.

With CAMS being an airborne sensor, it has flexible specification of flight lines for selected coverage of study area.
