Description
The name of the named tile to generate the tile
from. You must specify the location inside the repository
where the named tile is located.
Determines the zoom level of the tile to be returned.
The level shows how close the map image is to the
Earth. Level 1 is the furthest away and is composed
of one tile that the entire map will be drawn into.
Level 2 is composed of 4 tiles, 2 across and 2
down. Each tile is a quarter of the entire map. Level
3 is composed of 16 tiles, 4 across and 4 down,
and so on. The higher the level specified, the closer
to the Earth the map image appears. For example,
levels 1 to 3 usually show global or hemispheric
detail, levels 4 to 15 show county/state/province
level of detail and some larger cities, levels greater
that 15 show street level views.
What the levels actually display is dependant on
the named map published to the Map Tile Service.
For example, if you published a map of New York,
Toronto, or London then level 1 would be a street
level map of Toronto while high levels would be
more detailed.
This parameter must be set to a value greater than
or equal to the minLevel value and less than or
equal to the maxLevel value for the named map.
