MetacatUI

Draw markers on the map to represent individual markers when the geohash facet count is less than 3 or so. The threshold may increase as the zoom level increases, since at the whole world view we may only want to draw markers for geohash boxes that only have 1 dataset, but at a higher zoom level we may want to draw markers when a geohash box has less than 7. Or it may depend on the total number of results found rather than zoom level.

Because no document-specific information is returned with the facets (id, title, abstract, etc.), we would either have to send another query to get that information or a generic marker can be drawn and then that info will be requested via AJAX once clicked. (That would cause a slight delay between click and info window popup though).
