Water Basins (Special Secretariat for Water)

  This dataset is translated from Greek (EL) to English (EN). The original version is here.

This dataset contains the 45 river basins of the country as determined and mapped under the National Water Commission's Decision of 16 July, 2010, (Government Gazette, Series II, No 1383, 2.9.10 and Government Gazette, Series II, No 1572, 28.9.10, amending Annex II of previous Gazette) (ΦΕΚ 1383/B/2-9-10 and ΦΕΚ 1572/Β/28-9-10). The data are derived from the thematic layer of water basins in the database of Hydroscope (http://www.hydroscope.gr/). Polygons covering areas outside Greece have been removed from these data. Subsequently a generalisation of polygons of water basins was performed. Then the field 'namenl' which contains the Greek names that are compatible with Government Gazette, Series II, No 1572, 28.9.10 (ΦΕΚ 1572/Β/28-9-10) was added. The original data were created during the second phase of the NDBHMI project (1997-2005) through digitisation of HMGS maps of a 1: 50,000 scale. These data were adjusted to the borders that resulted from the digitisation of HMGS slides of a 1: 50,000 scale, which was performed in 1998, and the coastline provided by the Hellenic Navy Hydrographic Service, which was transformed from ED50 to GGRS87.
