Hi Lyndon,<br>
<br>
the projection is not the problem I just used the
cylindrical-equidistant projection to see the global map.<br>
<br>
The function gsn_add_shapefile_polymarkers reads the shapefile and
scan the global file attribute geometry_type. If it doesn't exist it
directly returns to the main script printing the error message.<br>
There are two ways to go on, you can copy and edit the
gsn_add_shapefile_polymarkers function or you can draw the
polymarkers as I did in the modified script using the
gsn_add_polymarker function.<br>
<br>
Bye, Karin<br>

<div>Dear Karin,</div>
<div><br>
</div>
<div><br>
</div>
<div>Thank you for the help. Actually, I was
able to plot this successfully by editing
the shapefile attribute manually in QGIS. I
need to plot it in orthographic projection
(Similar to the attached).</div>
<div><br>
</div>
<div>Is it possible to specify the "geometry
type" within the code (or edit the shapefile
attribute?) after reading the shapefile?</div>
<div><br>
</div>

</div>
<div>Many thanks,</div>

<div bgcolor="#FFFFFF"> Hi Lyndon,<br>
<br>
the problem is that your shapefile data does not contain
point data which is needed by
gsn_add_shapefile_polymarkers function <br>
<br>

<br>
To see what is in your shapefile you can draw the
shapefile data using the x- and y-values. I've attached
your modified script and the PNG plot.<br>
