I have huge database of lat/lon GPS coordinate points. For every point, I have several other variables (height, surface type, temperature, pressure...).
Also, data will be changed every day and old ones drop, no history.
I want to be able for given point find N-closest points in my database. Should I use PostGIS for this, or classic PostreSQL or MySQL is enough? I dont need any other data transformations, only finding closest (and even not by real distance in km). This is supported also by classic database systems and I am not sure if PostGIS is not like going with cannon to pigeon.
