Documentation
Definition
The layer dependency decribes the relation of a map layer to it underlaying map layers. Thus it only makes sense if more than one map layer is used in a map layer stack.
The property controls whether tiles of lower layers have to be rendered together with the tile(s) laying on top of them or if they may be rendered independently.
Use
The layer dependency can have the following values:
- all: The lower tiles have to wait for the upper tile(s) also, visually they are rendered as a unity.
- lower: The lower tiles may be rendered without the upper one(s) available.
- flexible: Usually the the dependency setting lower works well for zooming the map, but shows unnatural behaviour on moving if the upper layer is non-tile based. Therefore the setting flexible will act as the lower setting when the map is zoomed, but like all on move operations.
Dependencies
If the type of the layers is the same (tile based versus single picture) the dependency is defined for the matching tiles. If the upper layer isuses a single picture and the lower one is tile based, the upper picture has a dependency to every tile on the lower layer. If the upper layer is tile based and the lower one not, it is vice versa. In the rare case when the single picture is split at the 180° / -180° longitude tborder (so we have in fact two pictures) they are dependent to the tiles in their area.
