**Next, he placed a point in the center of Puget Sound and gave it an uncertainty. In essence he put a circle around the point - to enclose all the possible places in Puget Sound - where this specimen could be collected. Note that the value is really a "radius" of the circle (that has as its center, the latitude and longitude provided). The footprintWKT is a set of x,y coordinates that when joined by lines produces a polygon around the lat/lon point. Often polygons allow one to reduce the uncertainty compared to putting a circle around a point. But, they can get quite large (and so difficult to store in a spreadsheet or in a database). The take-home msg for this part is to talk to your IT people.

Hope you find this useful. Note that Pieter shares they'll add some more examples to the OBIS manual.
