any thoutghs?

 

here is some more new free stuffs, Gabon offers us Satellite Images for free on its new Geoportal, just click on this link to access it,   http://skytoearth.co...abon-geoportal/

What do you think? Personally, I think everybody wants a "free lunch". So if there's an option to choose between something that's free and something that's not, and they're about as good, we'll all go for the free version, right?

The problem is that the free lunch will always be made with the cheapest product, because it costs money to prepare food of higher quality, and that's harmful for the body, so they cant be about as good even though they might look like, 

 

there must be something else, definitely,

 

maybe things that have a price today have no value

Actually, there's some free GIS datasets out there, mainly the Natural Earth Vector that's in my opinion vastly superior to any comparable commercial source when it comes to data quality and reliability. All it takes is some dedication and a group of volunteers.

There is also the longstanding idea/model (tradition even?) that some data, like stuff from the USGS, should be available to the public at no charge because we already pay for it through taxes. So it's not really "free", we pay for it collectively, "up front" (as they say).

Hey Dave,

Try putting that same logic to the Ordnance Survey...

I think part of the difference between the US and UK national mapping and "free data" is the origins of the two agencies. The Ordnance Survey got its start as an aid to military and defense. The US Geological Survey was more about getting information to help "develop" the country, maybe especially the west. Military secrecy vs. public information. The former is more concerned about not letting enemies get that information too readily. The latter is more about getting the information out (and possibly getting a greater return on investment in the form of taxes?).

That's my (possibly over-simplified) understanding anyway. :)

There might also be more recent differences in culture:

OS under Thatcher: try to recover the costs

USGS under Reagan: don't spend any money
