Geo Mining in ELKI
Spatial data mining in ELKI is supported at various places.
Specialized Geo data mining algorithms
Geo distance functions
Defined for latitude-longitude pairs:
See DistanceFunctions for other distance functions.
Geo data types
- Regular number vectors (e.g. 2-d with longitude and latitude meaning)
See DataTypes for a complete overview.
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.
ELKI has specialized output support for geo data:
- de.lmu.ifi.dbs.elki.result.KMLOutputHandler for producing KML output files
