In the early days of GIS Stack Exchange it was recognized that every question here could be potentially tagged gis. Any question which could not, would be off-topic.
As a result that tag was blacklisted by Jeff Atwood using the blacklisting procedure and rationale discussed in Meta SE.
At the moment we have a tag called geospatial applied to 47 questions and its wiki defines it as:
A term widely used to describe the combination of spatial software and analytical methods with terrestrial or geographic datasets
This sounds a lot like GIS to me - should it too be blacklisted?
I think the same argument will also apply to spatial with 83 questions:
Related to or existing within space.
With what looks to be overwhelming support (7 upvotes, 0 downvotes on the question; 17 upvotes, 0 downvotes on the answer) I am going to proceed with burninate both tags (geospatial and spatial)followed by blacklisting them according to the procedures outlined in:
If anyone with full editing rights wants to help with the process please feel free to do so.
When the geospatial and spatial tags had their blacklisting completed today by Jon Ericson support for that being done was 12 upvotes (0 downvotes) on the question (which recommended blacklisting) and 27 upvotes (0 downvotes) on the answer (which was to endorse blacklisting).
