As far as I'm concerned, most of GIS related issues fit here. GIS Programming, GIS database development, GIS WebServices, GIS discussion, Cartography, Geography, etc. – George Jun 1 '10 at 21:34

What are the best databases for storing spatial data? Pros and Cons
added by Nathan W Jun 2 '10 at 11:29
link
This is a tricky one. Might be closed real early in the true website because it's subjective. I'm marking on topic, but with "remarks". A better question would be: "What is the best database extension to determine great circle distance between two points?" – George Jun 2 '10 at 11:42
I'm afraid that such questions just lead people to make a technos war... For me it's off topic, unless the text coming with the topic point out some details. – Agemen Jun 2 '10 at 11:44
I don't know if it's off topic, maybe just needs to be retitled. Comparing different databases is hard sometimes, that is why I think questions like this are good but yes it is subjective I agree. – Nathan W Jun 2 '10 at 12:10
If the question has to be renamed to be on-topic, i guess it's off-topic :p – Agemen Jun 2 '10 at 16:31

subjective with no right answer – Good Person Jun 3 '10 at 18:23

There could be a best answer for the questioner though, and it would be good to see all sources upvoted and downvoted. – geographika Jun 3 '10 at 19:36
This sort of question is rather common on SO, and quite on-topic if asked the right way, I think. – Hanno Fietz Jun 8 '10 at 22:18

Do you mean traffic data? Or street information (name, location, speed limit)? If it's the former it's one of the reasons I joined this proposal. +1 – eskerber Jun 9 '10 at 19:53
Street information. – Scott Wisniewski Jun 10 '10 at 6:00

While on topic, this might be suited for community wiki? – George Jun 2 '10 at 3:01
Yes of course, because there is no real answer community wiki would work well. These types of questions are good for getting people to share the hidden gem program they find. – Nathan W Jun 2 '10 at 3:17

I think this question shows an interest by someone to share knowledge with the next generation of GIS professionals. We should discourage that? – Michael Todd Jun 5 '10 at 3:57

Fair enough, you're better placed than me to decide that one.. social.msdn.microsoft.com/Forums/en-US/sqlspatial/… ;-) – Ti M Jun 3 '10 at 10:48
lol! busted! ;-) yep, I knew the answer already... i think its off topic for here. – Steve Jun 3 '10 at 10:52

People, we need to know why u think it is on/off topic to help define the boundaries of the site – Steve Jun 3 '10 at 20:53
I think this is Offtopic at all. There are tons of differences between programming for common apps and GIS apps. This SHOULD be a valid question. – George Jun 5 '10 at 6:11

First you will need to write a GUI in VB to track the IP address: youtube.com/watch?v=hkDD03yeLnU – Nathan W Jun 2 '10 at 5:15
oh my eyes!! Someday there will be a good correlation between IP address and location. That sure isn't the case today. – MotoWilliams Jun 3 '10 at 0:20

When you start using phrases like "segmentation fault", it's probably time to post to StackOverflow. – Matt Parker Jun 3 '10 at 21:08
5  
I disagree. I do GIS analysis using ogr, and thus GIS and programming are practicaly the same activity. GIS programming questions (i.e. specific to GIS libraries such as GDAL) should be welcome – fmark Jun 7 '10 at 11:48

This should not be off topic. Isn't the point of this site to bring together GIS professionals and are not programmers working with the largest GIS software vendor on the planet invited? – Robert Claypool Jun 11 '10 at 15:49
