Re: n-dimensional spatial data

'is it also possible to use n-dimensional spatial data with more than 2-dimensions with the GIS extension? '

Use Postgres. Not only can tt do this, it is even pretty quick in doing it.

What is missing in both implementations, but would be useful to have is removing the restriction to GIS data types for n-dimensional RTREE indices. Social networking queries often have the form of WHERE xpos BETWEEN xmin AND xmax AND ypos BETWEEN ymin AND ymin AND age BETWEEN agemin AND agemax AND otherattr BETWEEN attrmin AND attrmax ... This type of query would benefit a lot from RTREE indices, but translating the attributes into GIS points would be a nuisance.
