[postgis-users] load shapefile to postgis with SRID problem

[K Kuo]

Hi,
I am new to postgis and  have questions regarding SRID while loading 
shapefile to postgis.
I have a shapefile which is Maryland US and I would like to load it to 
postgis. What is the difference of using shp2pgsql with/without -s<SRID> 
option? Is it only important while re-projection or it's essential for 
creating database? Thanks
