Get a map based on lat long coordinates
Description
Get a map based on lat long coordinates
Usage
openmap(upperLeft, lowerRight, zoom = NULL, type = c("osm", "osm-bw",
"maptoolkit-topo", "waze", "mapquest", "mapquest-aerial", "bing",
"stamen-toner", "stamen-terrain", "stamen-watercolor", "osm-german",
"osm-wanderreitkarte", "mapbox", "esri", "esri-topo", "nps", "apple-iphoto",
"skobbler", "cloudmade-<id>", "hillshade", "opencyclemap", "osm-transport",
"osm-public-transport", "osm-bbike", "osm-bbike-german"), minNumTiles = 9L,
mergeTiles = TRUE)
Arguments
upperLeft |
the upper left lat and long
|
lowerRight |
the lower right lat and long
|
zoom |
the zoom level. If null, it is determined automatically
|
type |
the tile server from which to get the map
|
minNumTiles |
If zoom is null, zoom will be chosen such that
the number of map tiles is greater than or equal
to this number.
|
mergeTiles |
should map tiles be merged into one tile
