Description<br />
Chapter 4: Legacy <strong>Map</strong> <strong>Tiling</strong> Interface<br />
Specifies the name of the named tile from which<br />
the tile is generated. You must specify the location<br />
in the repository for the named tile.<br />
Determines the zoom level of the tile to be returned.<br />
The level shows how close the map image is to the<br />
Earth. Level 1 is the furthest away and is composed<br />
of one tile that the entire map will be drawn into.<br />
Level 2 is composed of 4 tiles, 2 across and 2<br />
down. Each tile is a quarter of the entire map. Level<br />
3 is composed of 16 tiles, 4 across and 4 down,<br />
and so on. The higher the level specified, the closer<br />
to the Earth the map image appears. For example,<br />
levels 1 to 3 usually show global or hemispheric<br />
detail, levels 4 to 15 show county/state/province<br />
level of detail and some larger cities, levels greater<br />
that 15 show street level views.<br />
What the levels actually display is dependant on<br />
the named map published to the <strong>Map</strong> Tile <strong>Service</strong>.<br />
For example, the levels demonstrated above are<br />
for Envinsa's High named map. If you published a<br />
map of New York, Toronto, or London then level 1<br />
would be a street level map of Toronto while high<br />
levels would be more detailed.<br />
This parameter must be set to a value greater than<br />
or equal to the minLevel value and less than or<br />
equal to the maxLevel value for the named map.<br />
You can determine these values by calling the<br />
getDescription method and examining the returned<br />
<strong>Map</strong>Description object. For more information, see<br />
getDescription on page 29 and <strong>Map</strong>Description<br />
on page 40.<br />
Specifies the column of the tile, based on the<br />
level parameter specified.<br />
