Hi all, I am developing an application that uses google maps as a front-end and postgis in the backend. Currently, we are using google mercator projection (SRID = 4326) for all geometries in the database. But, since we perform lots of geometric operations with these objects within the database, I am concerned about performance issues.
Wouldn't it be better if instead of a mercator projection, we stored all information in metric-based values? If so, is there any metric-based projection that works in any part of the world? Thanks for any help.
