The situation you describe is not very common - often when reading a shapefile it includes a "prj" file which describes the referencing information exactly. This is much better then "georeferencing" which is only a guess.
Still if your hear is set on georeferrencing check out this class: http://docs.geotools.org/latest/javadocs/org/geotools/referencing/operation/transform/WarpBuilder.html Jody Garnett On Fri, Apr 4, 2014 at 7:28 PM, suri <surendranath1...@gmail.com> wrote: > Hi , > > I am new to geo tools. > > Presently in our project we are doing reading and writing shape files (as > polygons maps) using geotools.
