Hello Johan
You can use these files in Postgis, setting the right SRID for them.
(a geographic system in your case)
You may also transform them to another reference system by knowing the
source and target spatial reference systems SRID. (transform()
function).
Storing them in lat-long won't allow you to compute precise distances, areas.
So transforming them to a cartesian reference system is a good option.
Look in the spatial_ref_sys table to find the SRID corresponding to
your projection.
