Hello Gianvito,<br><br>AddGeometryColumns does an additional operation, which is updating the table public.geometry_columns, used by most of OS GIS software to find out what is the column that contains the geometry, it's type and SRID. Also this function creates all the constraints necessary to use these softwares and edit these geometries in an error free way.<br clear="all">
<br>Well you should create your type in a normal way, but it will be impossible (i'm not 100% sure, just 95%) to use GIS software to edit geometries. You will need to use another way to acess your geometries and insert/edit them.<br>
<br>If the type is for other purposes, i guess you should be fine.<br><br>I'll let others more experienced to give their toughts.<br><br>George<br><br>-- <br>George R. C. Silva<br><br>Desenvolvimento em GIS<br><a href="http://www.sextantegeo2.blogspot.com">www.sextantegeo2.blogspot.com</a><br>
