<br><font size=2 face="sans-serif">Fabio, </font>
<br>
<br><font size=2 face="sans-serif">Glad to here you are here too :-)</font>
<br>
<br><font size=2 face="sans-serif">I can certainly use both GeoServer and
MapServer but this is not something I would like at the end. Since I am
still investigating all this, I am not in such a hurry to get it working
with my data ASAP. So, I would rather go with one of your Mapserver solutions.</font>
<br>
<br><font size=2 face="sans-serif">My first question, to be sure - so MapOl
reads/gets the GeoJSON data from Geoserver WFS and outputs GeoJSON data
to WebClient? If I understand Steve correctly, there is no way currently
to get GeoJSON output from MapServer WFS, only with CGI? So we come to
your solution 2.</font>
<br>
<br><font size=2 face="sans-serif">I have tried getting GeoJSON outuput
from MapServer using CGI, but I didn't succeed. There is little written
about this. I have tried setting something like:</font>
<br>
<br><font size=2 face="sans-serif">OUTPUTFORMAT</font>
<br><font size=2 face="sans-serif"> NAME 'geojson'</font>
<br><font size=2 face="sans-serif"> DRIVER 'TEMPLATE'</font>
<br><font size=2 face="sans-serif"> MIMETYPE 'application/json; subtype=geojson'</font>
<br><font size=2 face="sans-serif"> FORMATOPTION 'FILE=myTemplate.js'</font>
<br><font size=2 face="sans-serif">END</font>
<br>
<br><font size=2 face="sans-serif">but I got errors (using the newest MS4W
beta with MapServer 5.4.1)?</font>
<br>
<br><font size=2 face="sans-serif">Regarding my geometries - I am planning
to analyze some cadastral data (that's why I was so interested in your
"italian" example). This will be points and polygons mostly.
We have our cadastral data vectorized but still in dwg/multyline. We can
identfy parcels as points with parcel IDs, but in near future we'll make
polygons for all of them.</font>
