Hi,<br><br>I have a geotiff file which is rectangular but the actual image is irregular in shape and is surrounded on the outside by solid black. Since I have no need to display the outside black part of the file I would like to clip this out. I have already brought the geotiff file in ArcMap and drawn the outline of the image that I want to keep to a shape file. So I have the shape file and also the coordinates of that shape of the image that I want to keep.
<br>How can I clip out the image using either the shape file or the coordinates as input to this geotiff?<br><br>Thanks,<br clear="all"><br>-- <br>John J. Mitchell
