hello Norman.
I cannot find more info about this tool than here, so I wonder if it is still active? some successful use case and code from which to start? it would be very very helpful.
I am managing a dataset of about 15 milion records about biodiversity, each record with more than 30 columns that I want to filter with user demands. With postGIS it is becoming really slow and we are wondering if GeoCouch could help us.
I wanna created several degree grids for the entire world and apply a point-in-polygon to get how many records are in each degree cell. I understand this can be done relatively fast by GeoCouch, but what really worries me is the performance on plotting these geometries on the webmapping app. As we will get back GeoJSONs... let's say 500 'simple' (just degree cells, 4 coords), this would block the browser? (javascript has to transform this json to vectorial data). Currently using postGIS I get back a 300Kb JSON containing 1200 geometries.
So the ideal would be to request Couchdb and get back a WMS image via MapServer...
thanks in advance,
Pere
