Name Description
Type unit
GroundResolution The ground resolution is the distance between two contiguous pixels of
remote sensed imagery when projected on the earth. This parameter allows the user to select a range of acceptable ground resolutions.
Real Pair meter
InstrumentMode A categorical value used to specify a particular instrument configuration.
All possible modes should be defined in a code space, usually specific to the type of instrument.
ScopedName FusionAccepted
Specifies if imagery obtained by fusing several images acquired separately and co-registered is acceptable.
Boolean MinLuminosity
Minimum luminosity acceptable for the acquired imagery. This constrains the solar incidence angle of the acquired imagery.
Real

A different instrument mode code space than the one defined in this standard can be used when necessary. In this case, the code space shall be URL accessible and shall always
contain the ‘MULTISPECTRAL’ and ‘PANCHROMATIC’ options.
Requirement http:www.opengis.netspecEOSPS2.0reqopttasking-params-codespace-gml
Req 34. A custom optical instrument code space shall be URL accessible and
encoded in GML 3.2 format. The code space document shall pass the corresponding
conformance test class of [OGC 07‐036].
