In order to style my grid coverages of inundation which come to me as, I am using I am using the jgrasstools OmsRasterSummary to obtain the min and max range of the data, in order to come up with a proper styling (shades of blue) The minimum comes out to be -9999 which actually corresponds to no data. I am thinking that this is skewing my styling and really should have its own coloring. How exactly are the no values interpreted within the GridCoverage2D class? If I search for the min and max myself (thus explicitly discounting the -9999 no data points) I get a different min, max then OmsRasterSummary. Since the latter is using JAI operations on the Raster itself, I am assuming that it comes to these different values because it uses some type of interpolation to get the min max values at specific pixels. Is this a better approach? But what about the nodata pixels? Thanx Gaby
