referenced map (vector) and than mark identical point in the raster and vector
map to get coordinate of identical point in raster. Then I can transform raster
into my coordinate system. <BR><BR>First what I need is compute polynomial
formula to compute transform than I can compute output raster size after that I
have to go throw each pixel in the output raster and compute (using polynomial
formula) pixel from source raster.<BR

<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><SPAN lang=EN-US

problem is that source raster can be very large and other problem is that this

using GDAL? <BR><BR>I have source raster without geo reference and I have array
of identical point and each identical point has real geo coordinate. And I would
like transform source raster into coordinate
