Attributes

Required and optional XML attributes
Type String_64
Required

The type of dimension. Data users can determine the presentation to apply to each type of dimension. This element is not constrained but the simpleType enhancement_dimension_type provides some suggested standard classes of dimension.

Measure float
Required

The measurement being represented. No units are specified, but it is expected that all dimensions of the same type will be expressed in the same units, allowing uniform presentations to be applied in client applications.

FromFeatureId String_40
Optional

The ObjectId of the feature being measured from

ToFeatureId String_40
Optional

The ObjectId of the feature being measured to

RefLineFrom structure
Optional

A pair of decimal offsets in map units describing the extent of the reference line at the start of the baseline. Negative measures are left of the baseline, positive measures are right in the direction of the baseline. E.g: the values -0.5 4.0 represent a line through the start point, perpendicular to the baseline, that runs from 0.5m left of the baseline to 4.0m right. By convention the leftmost offset should be stated first.

StructureStructure
Left double
Required

The leftmost offset measure, in map units. By convention negative measures are left of the axis line and positive measures are right. Note that the leftmost offset may still fall to the right of the axis, so long as it is numerically less than the Right offset.

Right double
Required

The rightmost offset measure, in map units. By convention negative measures are left of the axis line and positive measures are right. Note that the rightmost offset may still fall to the left of the axis, so long as it is numerically greater than the Left offset.

RefLineTo structure
Optional

A pair of decimal offsets in map units describing the extent of the reference line at the end of the baseline. Negative measures are left of the baseline, positive measures are right in the direction of the baseline. E.g: the values -0.5 4.0 represent a line through the end point, perpendicular to the baseline, that runs from 0.5m left of the baseline to 4.0m right. By convention the leftmost offset should be stated first.

BaseLineOffset float
Optional

A single decimal offset in map units describing the position of the measure line parallel to the baseline. Negative measures are left of the baseline, positive measures are right in the direction of the baseline. E.g: the value 2.0 represents a measure line parallel to the baseline, that runs from 2.0m right of the baseline.
