Elevation Attributes in a Vertical Profile
Some of the attributes that can be produced by a VerticalProfileOperator are now obsolete, since the results are easier to get from the newer VerticalClearanceOperator. So the documentation of these attributes have been moved to this separate page.
These attributes are attached to the profile of the route itself that is generated when VerticalProfileOperator.OutputRoute = True, and they describe the highest terrain points near the route.
Attribute | Type | Meaning |
|---|---|---|
vpopMinIndexVisibleLeg | Integer | The minimal index of a visible leg (straight line segment) of the route. |
vpopMaxIndexVisibleLeg | Integer | The maximal index of a visible leg of the route. |
vpopEastingHighestPointLegk | Real | The Easting of the highest point on (or within maxDistance from) leg number k, for each valid k. |
vpopNorthingHighestPointLegk | Real | The Northing of the highest point on (or within maxDistance from) leg number k, for each valid k. |
vpopElevationHighestPointLegk | Real | The elevation of the highest point on (or within maxDistance from) leg number k, for each valid k. |
vpopCrsHighestPoints | String | The Name of the Crs in which the highest points are expressed. |
Explanations:
The legs of the complete route are numbered starting from 0.
A route leg can become invisible when you are zoomed in at a small part of the route (that is, the width of the View.Area or the width of a FeatureQuery.Area is less than the route length). Invisible route legs are not processed, so the highest points near them will not be found.
The k is a numeral, which is valid if it represents the index of a visible leg.
If only a part of leg is visible, then the leg index is regarded as valid, but only the visible part of the leg will be processed.
