[postgis-users] Coordinate transformation

[Yuriy Rusinov]

Hello, All !

I have to make coordinate transformation from one projection (300006) to
another (4024), make sql-statement
 SQL: select astext ( transform ( GeomFromText ('POINT (-2898380.75 -
2900345.00)', 300006),4024));
and sometimes I receive error transform: couldn't project point: -20
(tolerance condition error). Because I work with polar
regions I think that this error is connected with possible singularities in
projections. Which way I have to trace this cases ?
