Fabio, Glad to here you are here too :-)
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. 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. 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: OUTPUTFORMAT NAME 'geojson' DRIVER 'TEMPLATE' MIMETYPE 'application/json; subtype=geojson' FORMATOPTION 'FILE=myTemplate.js' END but I got errors (using the newest MS4W beta with MapServer 5.4.1)? 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. regards, dejan mapserver-users-boun...@lists.osgeo.org wrote on 01.07.2009 23:39:19: > Hello, > sorry ...but i read also this mailing list :-) > > Well, our project wants to be indipendent from web application used > to transfer GeoJson because GeoBI is compliant to the OGC standards > such as WFS, WMS, SLD, etc... > > Now, about this first implementation of GeoReport we used GeoServer > because it gives the possibilitiy to use in append to the WFS HTTP > request "outputformat=geojson" instead of GML. > > Anyway MapOl makes a WFS request and reads the output by using > mapfish-geojson-lib...so there are 3 ways to use MapServer to do the same: > 1. use a GeoJSON template for WFS output > 2. use a GeoJSON template for mapserver CGI output > 3.
