Caveats / Comments

The source dataset contains 547 administrative level 2 features with numeric ‘settlement’ codes.

These eight- or nine-digit codes begin with one or two digits that correspond to the quarters (administrative level 1 features) and then seven digits with no discernible significance.

Castries features have ‘1’, ‘2’, or ‘3’ prefixes that form non-geographically contiguous groups. As the names and significance of these groups are unknown, the Castries features were given a common and nationally distinct ‘13’ prefix in the OCHA P-code system. To preserve the ‘1’, ‘2’, and ‘3’ designations, to provide a distinct formulation for all of Castries features, and to maintain the source settlement codes the OHCA P-code system comprises the national code (‘LC’), the new prefixes (‘4’ to ‘13’) and the original settlement codes (padded to nine digits).

The source dataset had two administrative level 2 features, ‘Petit Piton’ and ‘Ti Delcer’ in Soufriere quarter with the same ‘settlement code’ (60720000). These have been given the distinct P-codes LC06060720001 and LC06060720002 respectively.

Some other sources (such as www.citypopulation.de) distinguish the ‘Central Forest Reserve’ (LC11110450000) as a distinct quarter but this is not supported by its settlement code.

The source dataset has hundreds of topological overlap and gap errors and appear to have had each boundary digitized at least twice. These errors were fixed arbitrarily.

The administrative level 0 KMZ file was generated from a generalized (0.0001 degree tolerance) version of the shapefile due to the shapefile’s number of vertices. The shapefile and geodatabase versions are the original.
