 #### Find interactions in a geographic areas
 
-Instead of a taxon-specific approach, users may also wish to gather information on all interactions occuring in a specific area.  For example, a group developing ecoystem models for the Gulf of Mexico may want to consider all the data from that region.  `rglobi` enables this type of search by allowing users to specify a rectangular bounding box. Coordinates must be in decimal degrees ([EPSG:4326 aka WGS 84 or WGS 1984](https://en.wikipedia.org/wiki/World_Geodetic_System)) and correspond to the west, south, east, and northern boundaries (i.e., min x, min y, max x, max y).
