need simple spatial search
Need to complete the spatial search screen for morpho. Needs to able to be
combined with others searches, so depends on some of the features described in

A simple graphical interface for spatial searches has been implemented. A map of
the world is displayed and the user selects a rectangular bounding box by simply
dragging the mouse. The map can be zoomed and the bounding box rectangle dragged
around the map. The latitide and longitudes indicated by the bounding box are
displayed in text boxes, and can be set by entering values (in several formats)
The interface is based on 'LiveMap' at
Note that the actual query based on this interface has not yet been implemented.

Problem with how Metacat handles non-numeric strings in bounding fields when a
'less-than' or 'greater-than' comparison is made. When non-numeric strings are
encountered, NO hits are returned. The Morpho side of the spatial query works OK
when there are no errors in metacat metadata.
A Metacat error describing the problem has been filed.
