Hi all again
Thanks ever so much for your help David your suggestion works great!
And thanks too MarkW for your help - exactly what I did but which
kept giving me the error message:
ERROR: column "azev2_1.the_geom" must appear in the GROUP BY clause or
be used in an aggregate function
SQL state:
You mean adding the field for output? Like this:
SELECT sitename,
astext(the_geom),
distance_spheroid(GeomFromText('Point(-70 20)', 4326), the_geom,
'SPHEROID["WGS 84",6378137,298.257223563]')
FROMazev2_1
GROUP BY 1,
2
HAVING distance_spheroi
Many thanks for your help David, it works!

Many thanks for your help David, it works!

Try this:
select astext(the_geom), distance_spheroid(GeomFromText('Point(-70
20)',4326),the_geom,'SPHEROID["WGS 84",6378137,298.257223563]') from

Hi all
I am trying to work out how to return the distances from a user
defined location but not too sure how. My query follows;
select * from azev2_1 where distance_spheroid(GeomFromText('Point(-70
20)',4326),the_geom,'SPHEROID["WGS 84",6378137,298.257223563]') <
25;
This provides all the po
