Data
Files, stable URLs, and what’s in them
Files
The regions are published at stable URLs under
https://australianantarcticdivision.github.io/measoshapes/data/v06/The same files are in the R package, in inst/extdata (find them with system.file("extdata", package = "measoshapes")), and are created by data-raw/export.R.
and a QGIS style, measo_regions06.qml (see QGIS).
Which to use:
- Polar equal area (
measo_regions06.*): areas, maps of the Southern Ocean, overlays with polar data. - Longitude/latitude (
measo_regions06_ll.*): assigning regions to longitude/latitude data, web maps. Boundaries are straight in longitude/latitude (see Definition). - EPSG:3031 (
measo_regions06_epsg_3031.*): polar stereographic maps, e.g. Quantarctica. Not equal area. - GeoParquet for data tools (R, Python, DuckDB, the browser); FlatGeobuf for GIS and streaming; GeoJSON for simple web maps.

name: region code, sector code then zone code (T for the temperate regions).label: full name, zone then sector, e.g. “Antarctic Atlantic”.sector: one of Atlantic, CentralIndian, EastIndian, WestPacific, EastPacific.zone: Antarctic, Subantarctic, Northern; empty for the T regions (outside MEASO).fill: the region’s colour in the MEASO Summary for Policymakers (Figure 5), as#RRGGBB; empty for the T regions.
Versions
The v06 in the URL is the version of the regions. Version 06 has the boundaries of version 05, with one row per region, labels, and the published colours; see Definition and News. Version 05 is available in the R package as released (measo_regions05), and as the geopackages in inst/extdata.
