RectifiedGridCoverage Generator

This generator offers an extension that allows the WPS to generate an output of the specific lattice, provided by the Inverse Distance Weighting Process, to an GML rectified grid coverage, which is a discrete point coverage based on a GML rectified grid. To use this generator with other processes, they have to use the IField Interface of the Inverse Distance Weighting Process or the generator has to be modified to fit to other inputs.

Detailed information about the rectified grid coverage can be found in OGC Geography Markup Language (GML) v. 3.1.0 – section 19.3.21

Installation and Configuration

This generator is shipped with the Inverse Distance Weighting Process. Please refer to Inverse Distance Weighting Process how to install it and come back again for configuration. Following the configuration manual at 52n Web Geoprocessing Service, you have to add the generator implementation (org.n52.wps.xml.RectifiedGridCoverageGenerator) in the comma-seperated list at the registeredGenerators property in the wps.properties file to enable this generator.


Refer to the how to use section at 52nWebProcessingService-IDWExtension. The RequestIdentifier for this generator is "RectifiedGridCoverage".
