hi,
Is there any way to calculate the extent(geom) on basis of the given distance from a point, such as the point is in the middle. I have tried the Distance(geom,geom)<50, for calculating extent, but it is very slow in processing. My data SRID is 27700, and so the units are meters, i want to extract the geom in the specified meters.
any help will be appriciated.
thanks
