Constructor Detail

GeoJSONGeoEnricher

public GeoJSONGeoEnricher(java.lang.String layersFolderPath,
                          GeoJSONSpatialLayerHierarchyConfiguration slConf,
                          Configuration conf)
                   throws java.lang.Exception

Creates a new instance

Parameters:

layersFolderPath - the folder containing the templates files which are the spatial data layers. This folder can be at any, a local or distributed file system.

slConf - contains information regarding to the spatial data layers to be loaded, such as, the data layers names and the hierarchical structure between the layers

conf - a hadoop configuration

Throws:

java.lang.Exception

Method Detail

enrich

public java.util.Iterator<SpatialFeature> enrich(JGeometry geomToEnrich)
                                          throws java.lang.Exception

Description copied from interface: GeoEnricher

Returns spatial features related to the given geometry

Specified by:

enrich in interface GeoEnricher

Parameters:

geomToEnrich - a geometry to be enriched with spatial features

Returns:

an iterator of spatial features. If no features were found for the given geometry, the iterator will be empty.

Throws:

java.lang.Exception
