Thank you very much Chris. I will take a look at "lanczons" method and check <br>whether I could use it to solve my simple problem once for all.<br>With best regards.<br>~Belaid.<br><br><br>> Date: Thu, 17 Sep 2009 15:56:33 -0700<br>> From: Chris.Barker@noaa.gov<br>> Subject: Re: [gdal-dev] pixel/line mapping for two images.<br>> To: belaid_moa@hotmail.com; gdal-dev@lists.osgeo.org<br>> <br>> Belaid MOA wrote:<br>> > I do not see how gdal_wrap could be used to find the pixels in the <br>> > source image that map to<br>> > the same pixel in the destination image?<a title="Send (Ctrl+Enter)" href="javascript:;" id="SendMessage"> <span class="Label"></span></a><br>> <br>> sorry for the typo, that's "gdalwarp"<br>> <br>> My point was not that you could use it to find the pixels, but that you <br>> could use it to do the whole job. gdalwarp takes one image, and warps it <br>> to create a new image, which can be a different projection and, I think, <br>> a different resolution.
