Example

1. The spatial extent of an Environment_Root within a transmittal, defined by the minimum and maximum latitude and longitude values (i.e. southwest and northeast corners).
2. The bounding parallelepiped of a Model of a building, in Local Space Rectangular coordinates.

FAQs

What is the purpose of this class?

This class provides FGDC-compatible metadata that describes the location and spatial extent of a high-level SEDRIS object (e.g., Transmittal Root, Model, Image, etc.) Spatial Domain allows potential users of a SEDRIS transmittal to evaluate the region contained by the transmittal without necessarily having to actually obtain or examine the transmittal itself.

How is the spatial domain of an object defined?

The spatial domain of an object is a simple bounding rectangle or parallelepiped that includes all of the Locations contained within that object. The bounding rectangle or parallelepiped is defined by two coordinate locations: the "minimum" corner, and the "maximum" corner, which represent the minimum and maximum values, respectively, along each of the axes of the spatial reference frame within which the object is defined.
