Reference definition of Sensor Model from ISO 19130-3:2022

[ghobona]

ISO 19130-3:2022 offers a definition of 'sensor model' that could be referenced by OGC API - Coverages.

Currently OGC API - Coverages offers its own definition in Clause 4.8.

Suggesting to change the Sensor Model definition to the ISO 19130-3:2022 definition:

mathematical description of the relationship between the three-dimensional object space and the 2D plane of the associated image (3.2) produced by a sensor (3.5)

cc. @alexrobin @cmheazel is that OK?

I like the fact that the definition from ISO19130 is more formal than the one currently in the document.

Unfortunately, the reference to a "2D plane of the associated image" makes it specific to imaging sensors, which is somewhat restrictive for coverages in general... I think you might want to associate other types of sensor models to coverages, such as the ones of LiDAR, profilers, etc...

@alexrobin Definitely.

@ghobona Alex has a great point, this 2D plane is way too restrictive, so that is a good justification for not using the ISO definition. That might be why Chuck had used this alternate definition.

How about:

mathematical description of the relationship between the three-dimensional object space and the corresponding dimensions of the associated coverage produced by a sensor (3.5).

[alexrobin]

@jerstlouis I like your definition, although I wonder if we should be more specific and call it the "geometric sensor model", as there are other aspects of a sensor model such as the "radiometric model", or more generally the "response model", which is linked to the range of the coverage.

The changes have been applied and no further feedback was received so so closing this issue.
