This past week has seen alot of activity in MapServer’s SOS Server Support. Remember when I posted about DataBlock? Well, Assefa did a great job in initially implementing this, and you can see the results in action right here. I’m going to be working on ensuring the XML conformance as per the SOS and OM standards, but it’s great to see this working!

This weekend, I added POST support. The SOS standard states that POST must be supported for all requests (except for GetCapabilities, which may be GET only). As a result, both GET and POST are now supported for all requests. I used libxml2‘s XPath support to parse the requests. XPath is an awesome way to parse XML! Support is not fully completed yet, as eventTime, result, and featureOfInterest are still yet to be implemented for POST (they are implemented for GET).

It will be interesting to see the mileage DataBlock gets. Especially seeing that now MapServer SOS presents a nice compact option to disseminate observation data over the web.

I’ll be at Ryerson University later today to celebrate GIS day. Ryerson University’s G. Raymond Chang School of Continuing Education GIS program is putting on a “Showcase of GIS Educational and Career Opportunities“.

So how are you celebrating GIS day? And what are your thoughts on GIS this year?
