class
BBoxTileSource
(**kwargs)¶ Bases:
bokeh.models.tiles.MercatorTileSource
The BBoxTileSource has the same default tile origin as the WMTSTileSource but requested tiles use a
{XMIN}
,{YMIN}
,{XMAX}
,{YMAX}
e.g.http://your.custom.tile.service?bbox={XMIN},{YMIN},{XMAX},{YMAX}
.-
use_latlon
¶ property type: use_latlon:Bool
Flag which indicates option to output {XMIN},{YMIN},{XMAX},{YMAX} in meters or latitude and longitude.

class
MercatorTileSource
(**kwargs)¶ Bases:
bokeh.models.tiles.TileSource
MercatorTileSource
is not generally useful to instantiate on its own, but is the parent class of mercator tile services (e.g.WMTSTileSource
).-
initial_resolution
¶ property type: initial_resolution:Float
resolution (plot_units / pixels) of minimum zoom level of tileset projection. None to auto-compute.
-
wrap_around
¶ property type: wrap_around:Bool
Enables continuous horizontal panning by wrapping the x-axis based on bounds of map. Note that axis coordinates are not wrapped. To toggle axis label visibility, use
plot.axis.visible = False
.
-
x_origin_offset
¶ property type: x_origin_offset:Float
x offset in plot coordinates
-
y_origin_offset
¶ property type: y_origin_offset:Float
y offset in plot coordinates
-

class
QUADKEYTileSource
(**kwargs)¶ Bases:
bokeh.models.tiles.MercatorTileSource
The QUADKEYTileSource has the same tile origin as the WMTSTileSource but requests tiles using a quadkey argument instead of X, Y, Z e.g.
http://your.quadkey.tile.host/{Q}.png
-
class
TMSTileSource
(**kwargs)¶ Bases:
bokeh.models.tiles.MercatorTileSource
The TMSTileSource contains tile config info and provides urls for tiles based on a templated url e.g.
http://your.tms.server.host/{Z}/{X}/{Y}.png
. The defining feature of TMS is the tile-origin in located at the bottom-left.The TMSTileSource can also be helpful in implementing tile renderers for custom tile sets, including non-spatial datasets.
-
class
TileSource
(**kwargs)¶ Bases:
bokeh.model.Model
A base class for all tile source types.
TileSource
is not generally useful to instantiate on its own. In general, tile sources are used as a required input forTileRenderer
.Subclasses should have these properties as well: x_origin_offset = Float y_origin_offset = Float initial_resolution = Float-
attribution
¶ property type: attribution:String
Data provider attribution content. This can include HTML content.
-
extra_url_vars
¶ property type: extra_url_vars:Dict(String, Any)
A dictionary that maps url variable template keys to values. These variables are useful for parts of tile urls which do not change from tile to tile (e.g. server host name, or layer name).
-
max_zoom
¶ property type: max_zoom:Int
the maximum zoom level for the tile layer. This is the most “zoomed-in” level.
-
min_zoom
¶ property type: min_zoom:Int
the minimum zoom level for the tile layer. This is the most “zoomed-out” level.
-
tile_size
¶ property type: tile_size:Int
tile size in pixels (e.g. 256)
-
url
¶ property type: url:String
tile service url (example: http://c.tile.openstreetmap.org/{Z}/{X}/{Y}.png)
-
-
class
WMTSTileSource
(**kwargs)¶ Bases:
bokeh.models.tiles.MercatorTileSource
The
WMTSTileSource
behaves much likeTMSTileSource
but has its tile-origin in the top-left. This is the most common used tile source for web mapping applications. Such companies as Google, MapQuest, Stamen, Esri, and OpenStreetMap provide service which use the WMTS specification e.g.http://c.tile.openstreetmap.org/{Z}/{X}/{Y}.png
