I am implementing a map application. There are towns with altitude,

One of the tasks is to be able to query N biggest (by population)

Hi Anton,
Have you considered using PostGIS? (http://postgis.refractions.net). It
implements the OGC SFS for geometries and is compatible with a large
number of open source viewers/tools such as Mapserver, Geoserver, QGIS,
OGR etc...
ATB,
Mark.
