Hi <div><br></div><div>Ok about this I just need to have an idea (or a link that can explain me this):</div><div>1- When I import a raster map (r.in.gdal) will it import all the raster or only the portion that fits in the current defined region?</div>
<div>2- If I define as a region a wider area than the image, will it process where the image is not available?</div><div><br></div><div>Thanks</div><div>Kim<br><br><div class="gmail_quote">2010/9/27 stephen sefick <span dir="ltr"><<a href="mailto:ssefick@gmail.com">ssefick@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Where you don't have the image, if I understand you correctly, would<br>
be NULL values? In that case you will have to default to someone more<br>
experienced, but I suspect that it is run on the entire map, but NULL<br>
means no data so no process. Just a wag.<br>
