Detailed Description

Interface to an Datamanager (ODM) object.

Datamanager objects are the central objects that can be managed by the DMlib. It allows managing huge geometry data sets with fast spatial access. For efficiency reasons points and other geometry objects (lines, polygons, etc.) are managed by different spatial indices. The interface gives access to the point index (see getPointIndex) and the other spatial index (see getPolylineIndex stores line and polygon data) separately or via the datamanager interface itself in a wrapped manner.

When create a datamanger instance, the datamanager uses a set of standard parameter which are appropriate for most data sets. However, it is possible to change these values using a ParameterSets object. The following parameters are supported:

Name type default Comment
StoreOrder bool false Flag if the order should be stored
PointsInMemory int 8*200000 Number of points that are kept in memory
AverageTilePointCount int 200000 Average point count per tile
TileSize double auto Tile size for tiling mode
