If you have GDAL 1.6 installed, you can use gdalbuildvrt to create a VRT of the files, and then link to this using r.external. This way you have a mosaic without duplicating the data. <br><br><div class="gmail_quote">On Thu, Jul 2, 2009 at 7:53 AM, Milton Cezar Ribeiro <span dir="ltr"><<a href="mailto:miltinho.astronauta@gmail.com">miltinho.astronauta@gmail.com</a>></span> wrote:<br>

<div> </div>
<div>I will try first download the latest SVN. In fact I am running a compiled version of 6.4R4, and I remember, on that time, few programs (like r.patch if I am not wrong) not compiled properly. Case it not work, I try r.series.</div>

<div>Thanks a lot,</div>
