| ‡a Category of material | The category of material to which the item belongs is a remote-sensing image. A remote-sensing image is defined as an image produced by a recording device that is not in physical or intimate contact with the object under study. This may be a map or other image that is obtained through various remote-sensing devices such as cameras, computers, lasers, radio frequency receivers, radar systems, sonar, seismographs, gravimeters, magnetometers, and scintillation counters. When the image has cartographic or bibliographic information added, it is referred to as a remote-sensing map. |
| ‡b Specific material designation | A one-character alphabetic code that describes the special class of material (usually the class of physical object) to which an item belongs. A fill character (  ) is used when no attempt has been made to code this position. | u | Unspecified. The specific material designation is not specified. | |
| ‡d Altitude of sensor | The general position of the sensor relative to the earth. | a | Surface. The image was made from a device on the surface of another heavenly body, usually a planet or a moon. | | b | Airborne. The image was made from a device in an aircraft, balloon, or other airborne device inside the primary layers of an atmosphere. | | c | Spaceborne. The image was made from a device in space outside the primary layers of an atmosphere, usually in orbit and beyond. | | n | Not applicable. The altitude of a sensor is not valid for the image. | | u | Unknown. The altitude of the sensor is not known. | | z | Other. None of the other codes is appropriate. | |
| ‡e Attitude of sensor | The general angle of the sensor to the surface being imaged. | a | Low oblique. The angle of the device is closer to parallel with the surface being imaged than perpendicular. | | b | High oblique. The angle of the device is closer to perpendicular than parallel. | | c | Vertical. The angle of the device is vertical to the surface being imaged. | | n | Not applicable. The attitude of a sensor does not affect the image. | | u | Unknown. The attitude is not known. | |
| ‡f Cloud cover | The percentage of cloud cover present when the image was taken. | 0 | 0–09% | | 1 | 10–19% | | 2 | 20–29% | | 3 | 30–39% | | 4 | 40–49% | | 5 | 50–59% | | 6 | 60–69% | | 7 | 70–79% | | 8 | 80–89% | | 9 | 90–100% | | n | Not applicable. The amount of cloud cover is not valid for the image. | | u | Unknown. The percentage of cloud cover is not known. | |
| ‡g Platform construction type | The type of construction of the platform serving as the base for the remote-sensing device. Platform is any structure that serves as a base, not only flat surfaces. | a | Balloon. The base for the device was a balloon or similar lighter-than-air platform. | | b | Aircraft—low altitude. The base for the device was a dynamic lift aircraft designed for low altitude flight—below 29,500 ft. (8,962 m.). | | c | Aircraft—medium altitude. The base for the device was a dynamic lift aircraft designed for medium altitude flight—between 29,500 ft. (8,962 m.) and 49,000 ft. (14,810 m.). | | d | Aircraft—high altitude. The base for the device was a dynamic lift aircraft designed for high altitude flight—above 49,000 ft. (14,810 m.). | | e | Manned spacecraft. The base for the device was a manned spacecraft. | | f | Unmanned spacecraft. The base for the device was an unmanned spacecraft. | | g | Land-based remote-sensing device. The base for the device was a land-based platform type. | | h | Water surface-based remote-sensing device. The base for the device was designed to remain on the surface of a body of water (e.g., a ship or floating platform). | | i | Submersible remote-sensing device. The base for the device was designed to be submerged beneath the surface of a body of water (e.g., a submersible vessel or platform). | | n | Not applicable. A platform construction type is not valid. | | u | Unknown. The platform type is not known. | | z | Other. None of the other codes is appropriate. | |
| ‡h Platform use category | The primary use intended for the platform specified in subfield ‡g (Platform construction type). | a | Meteorological. The platform's use is to make images of meteorological events and conditions. | | b | Surface observing. The platform's use is to make images of the surface of a planet, a moon, etc. (including the Earth). | | c | Space observing. The platform's use is to make images of space. | | m | Mixed uses. The platform's use is designed for a variety of uses (i.e., for images covered by two or more of the other codes). | | n | Not applicable. The platform use category is not valid for the image. | | u | Unknown. The platform use is not known. | | z | Other. None of the other codes is appropriate. | |
| ‡i Sensor type | The recording mode of the remote-sensing device, specifically, whether the sensor is involved in the creation of the transmission it eventually measures. | a | Active. The sensor measures the strength of the reflections of its transmissions sent to a remote target. | | b | Passive. The sensor measures, without stimulation, the strength of the transmissions (e.g., radiation) emitted by a remote target. | | u | Unknown. The recording mode of the sensor type is not known. | | z | Other. None of the other codes is appropriate. | |
| ‡j Data type | The spectral, acoustic, or magnetic characteristics of the data received by the device producing the remote-sensing image. Use for both wavelength of radiation measured and type of sensor used to measure it. Codes needing guidelines for application are defined. | nn | Not applicable. A data type is not valid for the image. | | uu | Unknown. The data type for the remote-sensing image is not known. | | zz | Other. None of the other codes is appropriate. | Visible Infrared | da | Near infrared | | db | Middle infrared | | dc | Far infrared | | dd | Thermal infrared | | de | Shortwave infrared (SWIR) | | df | Reflective infrared | | dv | Combinations | | dz | Other infrared data | Microwave (radar) | ga | Sidelooking airborne radar (SLAR) | | gb | Synthetic aperture radar (SAR–single frequency) | | gc | SAR–Multi-frequency (multichannel) | | gd | SAR–like polarization | | ge | SAR–cross polarization | | gf | Infometric SAR | | gg | Polarmetric SAR. | | gu | Passive microwave mapping | | gz | Other microwave data | Ultraviolet | ja | Far ultraviolet | | jb | Middle ultraviolet | | jc | Near ultraviolet | | jv | Ultraviolet combinations | | jz | Other ultraviolet data | Data fusion (combinations) | ma | Multi-spectral, multidata | | mb | Multi-temporal | | mm | Combination of various data types.
