Statistical Area 1 2018 (Centroid Inside)

SA12018_V1_00_Centroid_Inside is the inside centroid point layer for the major released version of the annually released statistical area 1 (SA1) boundaries as at 1 January 2018 as defined by Stats NZ.The "inside" centroid is a point which always falls inside each SA1 polygon as this is often desirable in some users cases. The placement of the point is typically in the widest part of the polygon. The algorithms used are proprietary to ESRI and are related to label placement. Note that the "inside" centroid is NOT always the same as the center of gravity ("true" centroid) of the polygon as in some situations the true centroid may fall outside the Meshblock geometry. The dataset contains the EASTING and NORTHING attributes of the centroid point in NZGD2000 New Zealand Transverse Mercator (EPSG:2193) and LATITUDE and LONGITUDE of the centroid point in decimal degrees in WGS1984 (EPSG:4326) projection.
