<pre class="moz-quote-pre" wrap="">Hello.
I am new to GDAL, and have spent the past two weeks exploring its use for (largely) nc —> tiff conversions. I am puzzled by a few things, however. I have a .nc file and when I use
</pre>

<blockquote type="cite" class="">
<pre class="moz-quote-pre" wrap="">ncdump -c file.nc
</pre>

<pre class="moz-quote-pre" wrap="">the coords are shown to me. The min x is 487200 and the min y is 4690100. The grid size is 100 m. If I then do:

<blockquote type="cite" class="">
<pre class="moz-quote-pre" wrap="">gdal_translate -of GTiff file.nc file.tif
</pre>

<pre class="moz-quote-pre" wrap="">and then
</pre>
<blockquote type="cite" class="">
<blockquote type="cite" class="">
<pre class="moz-quote-pre" wrap="">gdalinfo file.tif,
</pre>
</blockquote>
</blockquote>
<pre class="moz-quote-pre" wrap="">it shows the ‘lower left’ corner coordinates as
486790, 4690050
For the y coord, I can see how this makes sense…assume that ncdump is giving coords of the grid cell centers, not the ‘corner’ of the grid cells. Thus, the 50 m difference. For the x coord, the values are like 410 m different, so I am puzzled about that.
I am sure this is an overly simple question, but I would welcome any tips / guidance on what I am doing wrong. Thank you.
