oracle.spatial.hadoop.vector.shapefile.mapreduce.ShapeFileInputFormat

public class ShapeFileInputFormat
extends <any>

FileInputFormat for ESRI Shapefiles. The input has to be the main file (.shp). The directories in HDFS where the index files and DBF files are located can be specified. As well a directory to find .cpg files can be specified to define the encoding. By default the same directory as the main shapefile will be used. DBF and CPG files are optional. Keys are the position in the main file, and values are Maps with the attributes of the Shapefile record including the ShapeFileInputFormat.GEOMETRY_ATTRIBUTE.
