Hi Nisse, > I'm trying to build raster from shape input with decibel values, these > values should be used to colorize my raster.
As others have written, so long as the input shape file has exactly the spacing you want, then the rasterizer *should* do exactly what you want. I say should because we used your case as a test case and we noticed that we dropping the first column and first row if what you did was set the rasterizer to a column and row spacing -- we'll fix this. (Aside, that is why testing this with the column or row# as the "height" is very useful). The thing to remember is that the rasterizer will drop down the value for a point in the cell it is best overtop (a reverse nearest neighbour, if you will). Another way to do it is the DEMRasterGenerator, which will take in the points and output a raster from them, interpolating if necessary -- this would be useful if the input did not exactly match the output dimensions. We will do more testing and refinement of this over the next days, but in any case, attached is the workspace and you can fiddle with it. Note: The DEMRasterGenerator seems to take way to long for this input as well, so there's something for us to check into there too. Let us know what you think and how this will/will not meet your needs, and we can make adjustments accordingly. Thanks for the inquiry!
