[Geoserver-devel] [jira] Created: (GEOS-4664) Allows RangeLookup (reclassifier) process to specify noData and outputPixelsValues

Allows RangeLookup (reclassifier) process to specify noData and outputPixelsValues
----------------------------------------------------------------------------------

                 Key: GEOS-4664
                 URL: https://jira.codehaus.org/browse/GEOS-4664
             Project: GeoServer
          Issue Type: Improvement
          Components: WPS
    Affects Versions: 2.1.1
            Reporter: Daniele Romagnoli
            Assignee: Andrea Aime
            Priority: Minor
             Fix For: 2.1.2
         Attachments: rangeLookup.patch

Right now, the RangeLookup process allows to reclassify a continous coverage into a set of ranges identified by a number

Supposing you specify Ranges like [0;100][101;200][201;300] the produced coverage will contain pixel values 0,1,2,3 where:
0 means that the corresponding pixel of the input dataset wasn't in any of the specified ranges.
1 means that the corresponding pixel of the input dataset was in the range [0;100]
2 means that the corresponding pixel of the input dataset was in the range [101;200]
3 means that the corresponding pixel of the input dataset was in the range [201;300]

It would be good to allow specifying:
1) noData parameter, in order to override the default "0" value
2) outputPixelValues parameter, in order to override the default integer sequence 1,2,3,...n

As an instance a user would reclassify the previous 3 ranges on the output values of 50,150,250.

Patch is attached to be reviewed.
