Geo Mining in ELKI

Spatial data mining in ELKI is supported at various places.

Specialized Geo data mining algorithms

Outlier detection:

Additionally, you can use existing data mining Algorithms via specialized Distances.

Geo distance functions

Defined for latitude-longitude pairs:

See Distances for other distance functions.

Geo data types

See DataTypes for a complete overview.

Index support

Metrical Index Structures have support for geo data by using geographic distance functions.

Support in R-Trees is not yet complete, as we do not yet have an implementation of a valid min-dist for spatial rectangles on the earth sphere.

Output support

ELKI has specialized output support for geo data:
