Method Detail

getGridEnvelopeAsWkt

public static java.lang.String getGridEnvelopeAsWkt(java.lang.String params)

Get a grid envelope as WKT. Envelope one or more 'grid file name,minimum,maximum'.

Parameters:

params - comma separated grid file name,min,max,field.id2,min,max

Returns:

wkt representing the envelope as String.

getGridEnvelopeAsMultiPolygon

public static com.vividsolutions.jts.geom.MultiPolygon getGridEnvelopeAsMultiPolygon(java.lang.String params)

Get a grid envelope as MultiPolygon. Envelope one or more 'grid file name,minimum,maximum'.

Parameters:

params - comma separated grid file name,min,max,field.id2,min,max

Returns:

wkt representing the envelope as String.

streamGridEnvelopeAsWkt

public static void streamGridEnvelopeAsWkt(java.lang.String params,
                                           java.io.OutputStream os)
                                    throws java.io.IOException

Stream a grid envelope as WKT. Envelope one or more 'grid file name,minimum,maximum'.

Parameters:

params - comma separated grid file name,min,max,field.id2,min,max

Throws:

java.io.IOException

getGridSingleLayerEnvelopeAsWktIndexed

public static java.util.Map getGridSingleLayerEnvelopeAsWktIndexed(java.lang.String params,
                                                                   int[] map)

Get a grid envelope as WKT with index. Only one envelope 'grid file name,minimum,maximum'.

Parameters:

params - comma separated grid file name,min,max,field.id2,min,max

map - whole grid layer mapping to individual polygons. Accumulative on the same layer with min and max values that do no overlap

Returns:

Map containing "wkt" as String, "map" with updated input map, "index" as csv with records 'map value','wkt polygon character start position'.
