Hi everyone,
I have a small question regarding SharpMap.
I've downloaded the SharpMap project and I want to overlay a GdalRasterLayer over a VectorLayer ,but no success.
I don't know how can i convert my .tiff file coordinates to match exactly with the ESRI shapefile.
So can anyone tell me what's next after that line of code in order to setup my image?
SharpMap.Layers.GdalRasterLayer layRaster = new SharpMap.Layers.GdalRasterLayer("Raster layer", @"C:\world_raster.tiff");

Thanks in advance
