<b>Objet :</b> [gdal-dev] removing nodata voids from Geotiff<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hi<br>
<br>
I am wanting to fill (interpolate) nodata values in a Geotiff. (derived from SRTM data). They are small holes, usually just one pixel.<br>
<br>
I tried variations on this<br>
gdal_grid -a invdist -of GTiff S34E151.tif S34E151_grid.tif<br>
<br>
But it did not work, no error message - just returned the help page.<br>
<br>
I know this is not the main purpose of gdal_grid, but reading through the documentation I was hoping it would do the job.<br>
Any ideas on filling these gaps would be greatly appreciated. (pref using linux)<br>
<br>
Thanks<br>

Matt :)<o:p></o:p></p>
