The remote actions will be summarized activity in W3C RDF format generated by the IT thought process. The remote action is also a GIS data like remote sensing. Both remote sensing and remote action should use W3C RDF vocabulary when GIS interfaces with Postal Internet. The reference scale should be of metric units or relative units but not the indexed data like coordinates(spherical lat/long).

A Habitat is a zone like a farm or school or some “plant tissue” that has a real world reference. I also like GIS to be taught as course in early part of any degree course so that students can see their subject from GIS lens too.

My view, and it is only my view, is that such statements do nothing but fuel the fire of open source vs. closed source, when there is in fact merit in both, and it would appear to me that there is increasing evidence for following a hybrid approach (much as Esri themelves are doing, and promoting – see http://www.esri.com/software/open and http://www.esri.com/software/open/open-source).

I guess I’d be more inclined to say that future career growth lies where there is opportunity, rather than between alternative software licencing approaches.

But again, thanks for a really useful article, I will use it often!
