Hi,
I want to cut a raster with shp file,and the result raster will have the extent of the clipper's instead of the clippee's.(consider null or nodata as filled up)
Does this screenshot illustrate your requirement?
Two green checkerboards are original rasters,and red squares represent the extents of resulting rasters i.e.clippers' extents.
Hello,
I have a similar problem but I havent solved it yet.
I have a raster 1 band extracted from asc files (no problem).I want to tile it in different tiles following coordinates extended of a shapefile.If the tiles dont cover the shape extend they should be filled with any value but the coordinates should be the same than the shapefile (clipper).
If I apply only Clipper tranformer the tiles are ok but the coordinates extend dont follow the shape extend because the tiles are smaller and dont fill the no data.
If I also add Mapnik rasterizer the coordinates of tiles are ok but the tiles are RGB and empty.
Many thanks!
Use the clipper,make sure Preserve Clippee Extents is set to No.You can explicitly set the NoData value before hand by using the RasterBandNoDataSetter,if you don't it defaults to 0
The Clipper transformer should be able to do that.Shape as Clipper,raster as Clippee,output from Inside (or in older versions Clipped_Inside.
Make sure both data sets are in the same coordinate system.
Not sure I fully understand,but is it perhaps the RasterTiler that you are looking for?
