-These have come originally from [http://gadm.org GADM] but with their L1 removed (so we use their L2 as our L1, etc)
-* GADM file has terrible problems with place names: at least 3 different encodings!
-* These have mostly been resolved & the file contains place names with no diacritics (to make it easier for non-Vietnamese to search for such places) as well as Vi name_l10n
-* Many updated boundaries from http://gis.chinhphu.vn by selecting the place & then using this JS:
-{{{
-points = plHighlight[0].latlngs[0];
-output = 'POLYGON ((';
-for (var i=0; i < points.length; i++) {
-    p = points[i];
-    output += p.longitude;
-    output += ' ';
-    output += p.latitude;
-    output += ',';
-}
-output = output.slice(0, -1);
-output += '))';
-}}}
-or
-{{{
-output = 'MULTIPOLYGON (((';
-points = plHighlight[0].latlngs[0];
-for (var i=0; i < points.length; i++) {
-    p = points[i];
-    output += p.longitude;
-    output += ' ';
-    output += p.latitude;
-    output += ',';
-}
-output = output.slice(0, -1); // Strip comma
-output += ')),((';
-points = plHighlight[1].latlngs[0];
-for (var i=0; i < points.length; i++) {
-    p = points[i];
-    output += p.longitude;
-    output += ' ';
-    output += p.latitude;
-    output += ',';
-}
-output = output.slice(0, -1); // Strip comma
-output += ')))';
-}}}
-& then converted to WGS84 using:
-{{{
-ogr2ogr -f CSV CSV VN2000 Polygons.csv -s_srs EPSG:3405 -t_srs EPSG:4326 -lco GEOMETRY=AS_WKT
-}}}
+These have come from  Viet Nam Red Cross.
 * Old boundaries have been left and start / end dates have been added from Wikipedia.
+- the latest changes have unknown dates currently so are using 2015-01-01 until these are known.
