[OSM-talk] Quarry or construction?

[John F. Eldredge]

Of course, a large water-filled hole, without vehicles around it, describes both an inactive quarry and an inactive large-scale building site.  Given the current state of the world's economy, there are a certain number of the latter around, because the developer went broke.

curved vehicle tracks suggest quarry
presence of straight lines which suggest buildings under construction
area with large pooled water with copper-ish discolouration suggests quarry

i'd check council minutes for the area and see if you can use a search engine
to find what this land is used for
Even if you get he street names off another map.
