Hello Yang, RasterTpVectorProcess was rewritten and is now called PolygonExtractionProcess. The usage is slightly different (just create an instance of the class directly) and should be clear from the javadocs. You can find it in the process-raster module in the ...raster/gs package:
http://svn.osgeo.org/geotools/tags/8.0-M4/modules/unsupported/process-raster/src/main/java/org/geotools/process/raster/gs/ If you are working with a large grid, it might be a lot easier to do it another way. For example, generate the LineStrings for the grid in the X direction (you only need the end points) and cut your route lines with those, then generate LineStrings for the Y direction and do another pass.
