Note: North/South and East/West coordinates should not be equal. If the data are a point or a line, please provide 4 different coordinates with at least an epsilon difference between them (e.g. 0.001).
The bounding box is used mainly to enable spatial searches and data comparison. By the way, it needs to be standardized and that is why it must be expressed using geographic WGS84 coordinates.
It should be for the information content at a minimum. It may include no-data areas since it is a rectangle, whereas the content can be something else. There could also be 'holes' within the data. Based on security issues, some portions may not be releasable.
The properties of Geographic Box are listed below.
