Class Summary

Class	Description
AbstractSpatialHierarchicalMapper<K,V,W>	Base mapper class used to catalog records into hierarchy layers.
BufferMapper	A mapper implementation that generates a buffer for each record containing a geometry.
HierarchicalCountReducer	A reducer that takes the output generated by SpatialHierarchicalCountMapper and creates a different output for each hierarchy level.
IndexedSpatialFilterMapper<K,V>	Reads a local spatial index and takes all the records that satisfy the spatial operation and query window specified in the job configuration
MVSHierachicalCountMapper<K,V>	This mapper implementation catalogs records in different hierarchy levels using MVSuggest.
SpatialFilterMapper<K,V>	Emits all the records that satisfy the spatial operation over the query window specified in the job configuration
SpatialFilterReducer	Output a query window and all the records associated with it in JSON format
SpatialHierarchicalCountMapper<K,V>	This implementation of AbstractSpatialHierarchicalMapper outputs as value a single count for each hierarchical entry.
SpatialHierarchicalJoinMapper<K,V>	This implementation of AbstractSpatialHierarchicalMapper outputs as value every matching RecordInfo.
SpatialIndexingMapper<K,V>	This mapper generates a spatial index for each FileSplit input value.
SpatialMVSHierarchicalCountMapper<K,V>	Mapper class that categorizes input records into features defined in a hierarchical dataset.
