Map
draws a Map for a latitude/longitude on an axes. Mapper
sets
up a simple GUI for a map, where the user can select a place and a
style for the map. The place will be converted to latitude/longitude
coordinates using the Google geocoding API.
map = Mapper('Oldenburg');
The map consists of tiles downloaded from openstreetmap. Whenever the axes limits are changed (pan/zoom), or coords is updated, new map tiles are downloaded as appropriate. Map tiles are cached, and are never re-downloaded.
The map will make sure that map tiles are always drawn at the bottom of the draw stack, so that users can draw their own things on top of the map.
The map tiles can be downloaded in one of several styles:
'osm'
for OpenStreetMap's default look'hot'
for humanitarian focused OSM base layer'ocm'
for OpenCycleMap'opm'
for public transport map'landscape'
for Thunderforest landscape map'outdoors'
for Thunderforest outdoors map
(from: http://wiki.openstreetmap.org/wiki/Tiles)
All map drawing is done asynchronously, so user interaction with a GUI is not interrupted by tile downloads.
