<p>Hi Frank</p>
<p>Thanks for looking into that.</p>
Just discovered what foxed me:<br>
<br>
Unusually ,there was <i>no error message</i> telling me that
neither the .hgt nor .zip file were found .<br>
<br>
Perhaps, the error message does not occur because I'm using
usedummydata?<br>
<br>
In which case, it would still be very useful to know if it can't
find .hgt or .zip<br>
<br>
This is what I get when I parse the large pbf <br>
