GET /records/{metadataUuid}/extents.json

A rendering of the geometry as a png. If no background is specified the image will be transparent. In getMap the envelope of the geometry is calculated then it is expanded by a factor. That factor is the size of the map. This allows the map to be slightly bigger than the geometry allowing some context to be shown. This parameter allows different factors to be chosen per scale level. Proportion is the proportion of the world that the geometry covers (bounds of WGS84)/(bounds of geometry in WGS84) Named backgrounds allow the background parameter to be a simple key and the complete URL will be looked up from this list of named backgrounds
