+1 on mergers.

But, at the risk of trivialising, what I actually find even stranger is that at the core, geo is really about two numbers (lat,long) or 3 if you want to add altitude (and yes, even a polygon is just a container of coordinates)- its not really semantic. Yet we see a lot of effort going into this nowadays.

What IS semantic is the context or meaning people assign to those coordinates - I call a country  Burma, you call it Myanmar. I call where I am "home", you call it Block and Section x and cadastre #y. To you another place is a postal address, to me it's a geoIP location of a user. And yet I receive looks of horror from GIS pros when I tell them I'm running an enterprise government mapping system with nothing more than Tilestache, Open Layers and Drupal, where location is just a type of content I can assign a geocode to and put it on a map - because the coordinate doesn't change, just how I describe the thing that is there.

I, with one foot in the Geospatial community, and other limbs and fingers being in the web, data management, LOD, metadata, cartography and visualisation, to name a few, cannot help but note that while the GIS community really know their stuff, they often lack the "people" focus of the SemWeb community - I still argue with my father the town planner and surveyor for instance that no one but his profession and the stats crowd call a home a "dwelling" and ones hometown a "population centre".

I'd strongly urge the spatial crowd to reach out to other professions who specialise in looking at how people view the world around them and work along side them - why reinvent the wheel when all it takes is just

a) plugging a geocode (in an OGC standards compliant manner of course) into a semantic reference, and;

b) realising that GIS is already linked data and ready to be triplified so easily.

[latlong] [hasContext] [placeA]
                 [hasContext] [placeB]
                 [hasContext] [placeN...]

What SemWeb and LOD need from the Geo crowd more than anything IMO is standardised spatial systems for us to reference - for instance, accurate high res maps at low levels, more geocoded datasets, more open source tools, standardised map icons, and more of all of it :)

Cheers

Chris
