The SEDRIS Data Representation Model

The spatial extent of the containing object.
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).
The bounding parallelepiped of a <Model> of a building, in Local Space Rectangular coordinates.
This class provides [CSDGM]-compliant 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.
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.
The first <Location> is the "minimum" corner, that is, the southwest corner. In the case of a 3D <Spatial Domain>, the z / elevation value of this <Location> is the minimum elevation of the bounding volume being specified, rather than the elevation at the southwest corner. The second <Location> is the "maximum" corner, that is, the northeast corner. In the case of a 3D <Spatial Domain>, the z / elevation value of this <Location> is the maximum elevation of the bounding volume being specified, rather than the elevation at the northeast corner.
