net.simplace.processors.LineFeatureCollectionInfoProcessor

Version: 1.0

This processor delivers informations of a org.geotools.feature.FeatureCollection of geometry type com.vividsolutions.jts.geom.LineString and one of its org.opengis.feature.FeatureFeatures. Besides the (general) informations of the super class, this processor stores in following in the output parameter map:

startPoint.x: Latitude of the feature's start point
startPoint.y: Longitude of the feature's start point
startPoint.value: raster value of the start point (only provided if input raster is specified!)
endPoint.x: Latitude of the feature's end point
endPoint.y: Longitude of the feature's end point
endPoint.value: raster value of the end point (only provided if input raster is specified!)
min.value: Minimum Raster value the line string crosses (only provided if input raster is specified!)
max.value: Maximum Raster value the line string crosses (only provided if input raster is specified!)
border.min.value: Minimum of start and end point: min(startPoint.value, endPoint.value) (only provided if input raster is specified!)
border.max.value: Maximum of start and end point: max(startPoint.value, endPoint.value) (only provided if input raster is specified!)

Required input parameters (besides the super class parameters):

Key rasterParamKey (optional): key where to find a org.geotools.coverage.grid.GridCoverage2D. Also a de.schmitzm.geotools.styling.StyledGridCoverageInterface is allowed.

If rasterParamKey is not specified, all value... output parameters remain null.
