<p class="MsoNormal"><span lang="EN-US">While in the process of upgrading from 2.2.4 to 2.4.4 we encountered an issue with a specific NETCDF file which can no longer be warped.<br>
Sample files can be found at : </span><a href="ftp://msgcpp-ogc-realtime.knmi.nl/"><span lang="EN-US">ftp://msgcpp-ogc-realtime.knmi.nl/</span></a><o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-US">The file is a multiband dataset from which we want to extract the
<b>precip</b> data, it contains 2 bands for georeferencing Lat/Lon.<br>
So in 2.2.4 we used the -geoloc warp parameter to correctly warp it to a Webmercator or Mercator projection, this was done with the c-sharp swig bindings.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">With 2.4.4 the program just halts and does not continue, the same can be reproduced with the commandline gdalwarp tool :
<br>
gdalwarp -geoloc -r cubic -t_srs "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs" NETCDF:"samplefile ":precip "output.tiff"<o:p></o:p></span></p>
