Hi, <div><br></div><div>As i mentioned in my couple of previous mails, I found that v.surf.rst function does not work</div><div>for either 2D point or iso-lines unless "Use Z coordinates for approximation" flag is ticked </div>
<div>together with the selection of the <b>name</b> of the attribute column with values to be used for</div><div>approximation. When both are chosen, it runs and gives the expected output.However</div><div>I think there is a minor bug in this function and it should be rectified and made work for</div>
<div>2D data sets without selection of Z flag. The version of GRASS i used is WINGRASS 7</div><div>installed through OSGEO4W installer.</div><div><br></div><div>Cheers, Brian.</div>
