Dear List members,<br><br>I am requesting help again on the problem below. If anyone has used the moving average functionality in gdal_grid, it would be great to see your example, especially if you have produced outputs that either are netcdf or ascii grids, or could be converted to them via gdal_translate or imagemagik convert. <br>
<br>Regards,<br>-Andy<br><br><div class="gmail_quote">On Tue, Jan 26, 2010 at 11:10 AM, Andy Wood <span dir="ltr"><<a href="mailto:awood@3tier.com">awood@3tier.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
