Hi , 

I was just wondering , at the moment I am using the following command to
enter data into my database. 

insert into
table(id,poly_geom,name,level)values(1,GeometryFromText('POLYGON((5
2.30 -9.75 0,52.30 -9.66 0,52.25 -9.66 0,52.25 -9.75 0,52.30 -9.75
0))',-1),'


If I wanted to integrate height also into my table of polygons would I
just replace the zero value with the height in meters. 

Once I then query the database for places within a 30km range will it
take the height into account when It returns my result. 

Any help appreciated 

regards
