Geographic systems 2
Latitude and longitude on the ellipsoid of a datum. They underlie the projected systems of the same datum.
Regional and world-wide systems that also cover this country 1
UTM zones, continental grids and frames shared with other countries.

Which system should I use?
For a plan or a survey in this country, use the national system named by the specification or the cadastre. A UTM zone suits a project that spills over national zones; WGS 84 (EPSG:4326) is for exchanging with a GPS.
