comment How to save MapServer output to a file?
That does not work for me. I get a file of this type mapserv.cgi?map=..%2F..%2Fmapfiles%2Fdemo.map. If I try renaming it to test.png it is not an image (I should have included this in my question as I had also tried it).

comment Can OpenStreetMap be used as a WMS service in MapServer?
Thanks for the suggestion. I am currently combining these on the browser side using OpenLayers, and an OSM base-map but I am interested in combining them on the server side also.

comment Can OpenStreetMap be used as a WMS service in MapServer?
Thanks for the suggestion. For the linked OSM WMS, do you know what the connection info would be? For example I can find http://129.206.228.72/osm-proxy/service? but nothing with WMS in the address.

comment How to import shp files into postgresql with PostGIS?
What method are you using to upload the shapefile? This looks a little like the error from the SPIT upload tool in QGIS.

comment What are cloud-based alternatives to Google Fusion Tables?
You would need to use a database to store data of this type. Postgresql with PostGIS is an opensource combination that can help with the storing of it.

comment Spatial Join on two point featureclasses produces empty output featureclass
As a test, could you try performing the same operation in QGIS? One approach could be to buffer the points by a small amount to create polygons, and then to spatially join the points to polygons (checking that you only get one point per polygon).

comment How can several vector layers have different controls, using Openlayers?
Thank you, this works well for selected features when clicked. I'm still not managing to make it work for a feature that is highlighted, as I want to call a function when this occurs. Is this possible?

comment How can several vector layers have different controls, using Openlayers?
Yes, but I want to have different functionality for each layer which is why I separated them.

comment How to get an ocean shapefile from a very detailed land area shapefile?
I assume, when you created your world polygon that you projected it into the same system as the land data?

you can also set your IPv4 connection to use trust which should allow you to connect locally.

comment Is it possible to change the projection used in OSM2PO?
I'll try it out. I was a bit nervous changing it in case I misunderstood how these values were being calculated but this seems like a good approach.

comment Is it possible to change the projection used in OSM2PO?
I don't think it's possible to transform x1, y1, x2, y2 as they are not geometric or geographic objects. However, if they are only used for aStar maybe it it does not matter too much.

DUMP "true" appears to be deprecated mapserver.org/mapfile/layer.html (and pink tiles were overlaid on map).

comment How to use getfeatureinfo with MapServer and OpenLayers?
ah ok. Thanks for the suggestion. I just added TEMPLATE "body.html" into my mapfile and created an empty file 'body.htmll'. I'm still getting the error that my layer is not queryable though.
