Functions

default_style()

source code

get_features(uids, user)
Returns list of tuples representing mapnik layers Tuple => (model_class, [pks]) Note: currently just a single pk per 'layer' which is incredibly inefficient but the only way to ensure proper layer ordering (??).

source code

auto_extent(features, srid=settings.GEOMETRY_CLIENT_SRID)
Given a set of staticmap features, returns the bounding box required to zoom into those features.

source code

staticmap_link(request, instances, map_name="default")
Generic link version of the staticmap view

source code

show(request, map_name="default")

source code

draw_map(uids, user, width, height, autozoom=False, bbox=None, show_extent=False, map_name='default')
Display a map with the study region geometry.
