Hello, last time i get shapefile witp Porto Portugal streets. I convert it to SQL an there was a column with data in SRID 27492. I added this data to database, create another column with 4326 SRID and transform data from 27492 to 4326 using:
UPDATE axes SET the_geom_wgs = Transform(the_geom,4326); ok later i expotr file to KML to se it in google earth but the geom is not shown in perfect position. It is moved to west south about 80 meters. I'm sure that data in 27492 is ok. So why after conversion it is not so good in google earth? Did I do something wrong? Or forgot about something? Maybe there are some additional options to correct it? Simon
