#A.16.IR20.IR21.ds.bounds

Purpose: A geographic bounding box must be given and it should be as small as possible

Prerequisites

• A.01.validate must be passed

Test method

Check if it's a valid geographic extend. It is described by 4 elements: westBoundLongitude, eastBoundLongitude, southBoundLatitude and northBoundLatitude. The test performs the following checks on them:

• Is a correctly formatted westBoundLongitude given at gmd:westBoundLongitude/gco:Decimal.
• Is the following constraint given: -180.00 = westBoundLongitude = 180.00
• Is a correctly formatted eastBoundLongitude given at gmd:eastBoundLongitude/gco:Decimal.
• Is the following constraint given: -180.00 = eastBoundLongitude = 180.00
• Is a correctly formatted southBoundLongitude given at gmd:southBoundLongitude/gco:Decimal.
• Is the following constraint given: -90.00 = southBoundLatitude = northBoundLatitude
• Is a correctly formatted northBoundLongitude given at gmd:northBoundLongitude/gco:Decimal.
• Is the following constraint given: southBoundLatitude = northBoundLatitude = 90.00;

The bounding box shall be as small as possible. Quite hard to honour. Data should be downloaded and a minimal bounds could be calculated and compared to the indicated bounds.

The bounding box shall be expressed in decimal degree with a precision of at least 2 decimals.
