Please email the list, and not the person directly.<br>
The purpose of lists is to pool knowledge, not to give
courses, so all conversations relevant to the list
should stay with the list.<br>
<br>
Judging by your unfamiliarity with raster and vector
data formats, it seems like you need deeper knowledge
about what you are doing, rather than just assistance
with the use of QGis.<br>
<br>
I don't have any URLs I can suggest for this, but
perhaps someone else on this list can help.<br>
<br>
Kind regards,<br>
Zoltan<br>

<div>Dear Zoltan,</div>
<div>Many thanks for your prompt reply. I have not
used shape file before so you have to walk me
through. My DSM is in .tiff format. Can I use that
instead of .shp?</div>
<div>Please give me a sample of an acceptable output

Yep, true - if your 'Temp.shp' is not a DIRECTORY
within your documents folder.<br>
<br>
What you and I call "shapefiles" is actually a
group of 3 or more files that are needed by ESRI
and other GIS products that use 'shapefile format'<br>
<br>
For this reason you must specify the name of an
existing directory, and not a filename that you
want to create.<br>
<br>
<font color="#006600">Are you sure the "other
paths" you tried existed and were actually
directory names?<br>
