New Class - NominalResolution

[stansmith907]

Class Definition: nominalResolution
"distance between consistent parts of (center, left side, right side) adjacent pixels"

Rules:

• optional

---

Element Definitions:

• scanningResolution: { measure } "distance between consistent parts of (center, left side, right side) adjacent pixels in the scan plane"
• groundResolution: { measure } "consistent parts of (center, left side, right side) adjacent pixels in the object space"

Rules:

• only one may be selected. Although this type of restriction is generally a writer consideration, in this case having both values is not logical.
• both elements are "distance" measures. So type is fixed as "distance". It may be OK to drop type from mdEditor, but it will remain part of { measure } and thus output by mdJson writer.
• scanningResolution: required if not groundResolution
• groundResolution: required if not scanningResolution
