Admin 1 – States, Provinces
+
About
+NOTE: This theme is still in beta!
+Internal, first-order administrative boundaries and polygons for all but a few tiny countries. Includes name attributes (including diacritical marks), name variants, and some statistical codes (FIPS, ISO, HASC).
+Looking for Cyrillic or Chinese characters? The GeoDB format preserves local scripts better than SHP format.
+Admin-0 units that lack admin-1:
+Antarctica, some disputed areas, tiny island nations, and principalities such as Monaco, Andorra, Liechtenstein, and San Marino.
+How-to
+Use the following selection statement to derive this theme from the 10m lakes:
+“ScaleRank” <=2
+Then punch those selected features through the admin-1 and save result as a new feature class.
+Issues
+This is the toughest dataset to keep current. Unlike the United States, other countries constantly rearrange their admin-1 units, slicing and combining them on a regular basis.
+We need help making sure our statistical codes are correct if they are present and about half the dataset needs them added, still.
+Just a few admin-1 units lack a name. For names we are unsure about, those are flagged as an attribute.
+A separate version should be created for “region” groupings of admin-1. Many countries, like France, include top level regions and departments, both as admin-1 ranking. If we only have their “region” admin-1, the department version needs to be digitized.
+Boundaries should perfectly match the following NEV themes:
+Coastline, lake shoreline, admin-0 country boundary, river and lake centerlines.
+Some boundaries in Brazil, north Africa, and central Asia do not have enough data points on straight line segments. This is a concern when reprojecting the data. This is planned to be corrected in a 1.1 update.
