Definition

In regard to spatial <Axis> instances,

1. A spatial <Axis> instance is an <Axis> instance with one of the following as its axis_type.

   1. For angular coordinates, such as latitude and longitude, EAC_SPATIAL_ANGULAR_PRIMARY_COORDINATE and EAC_SPATIAL_ANGULAR_SECONDARY_COORDINATE;

   2. For x, y coordinates, EAC_SPATIAL_LINEAR_PRIMARY_COORDINATE and EAC_SPATIAL_LINEAR_SECONDARY_COORDINATE;

   3. For z and elevation coordinates, EAC_SPATIAL_LINEAR_TERTIARY_COORDINATE

2. The number of spatial <Axis> components of a <Property Grid> instance is specified by spatial_axes_count. These spatial <Axis> components shall be the first listed <Axis> components of the <Property Grid> instance, and each shall correspond to a distinct coordinate-component of the SRF of the <Property Grid> instance.

3. No other <Axis> instances in any other context shall be spatial.

4. A spatial <Regular Axis> instance or <Irregular Axis> instance shall not have interpolation_type set to SE_INTERPTYP_DISALLOWED.
