Parks and protected areas – US National Park Service units. Urban polygons – derived from 2002-2003 MODIS satellite data. We favor regional significance over population census in determining rankings.

Includes capitals, major cities and towns, plus significant smaller towns in sparsely inhabited regions. Populated places – point symbols with name attributes. Includes names attributes and some statistical groupings of the same for smaller countries. Pacific Island Territories) and sub-national map subunits (Corsica versus mainland Metropolitan France).ĭisputed areas and breakaway regions From Kashmir to the Elemi Triangle, Northern Cyprus to Western Sahara.įirst order admin (provinces, departments, states, etc.) – internal boundaries and polygons for all but a few tiny island nations. Includes dependencies (French Polynesia), map units (U.S.

Raster data includes grayscale-shaded relief and cross-blended hypsometric tints derived from the latest NASA SRTM Plus elevation data and tailored to register with Natural Earth Vector.Lines contain enough data points for smooth bending in conic projections, but not so many that computer processing speed suffers. Projection friendly-vectors precisely match at 180 degrees longitude.Large polygons are split for more efficient data handling–such as bathymetric layers.Know that the Rocky Mountains are larger than the Ozarks. Vector features include name attributes and bounding box extent.

It can also be described as a PROJ4 code EPSG:4326 string “+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs”. Projection: Natural Earth’s WGS84 projection is specified in shapefile’s PRJ file. Version 3 of Natural Earth switched to UTF-8 and version 4 fixed encoding conversion errors and omissions. Natural Earth shapefile character encoding is specified in the code page flag in the shapefile’s DBF file and for additional compatibility is also specified in the CPG file. GDAL/OGR and Postgres/PostGIS also support UTF-8. ArcGIS supports UTF-8 since version 10.2.1, and their technical article has details on configuring earlier versions to work with UTF-8. Applications like QGIS and OpenOffice handle UTF-8 well.

Initial versions of Natural Earth were in the Windows-1252 encoding limited to Latin-based scripts.

Assigning different colors to contiguous country polygons is another task made easier thanks to data attribution.Ĭharacter encoding: Natural Earth uses UTF-8 character encoding to support internationalization with a full range of language scripts (and even emojis: ?). For example, width attributes assigned to rivers allow you to create tapered drainages. Up to eight rankings per data theme allow easy custom map “mashups” to emphasize your map’s subject while de-emphasizing reference features.

Most lines and areas contain embedded feature names, which are ranked by relative importance. Intelligent data: The attributes assigned to Natural Earth vectors make for more efficient mapmaking. Natural Earth Raster comes in TIFF format with a TFW world file.Īll Natural Earth data use the Geographic coordinate system (projection), WGS84 datum Natural Earth Vector comes in ESRI shapefile format, the de facto standard for vector geodata.

Unlike other map data intended for scientific analysis or military mapping, Natural Earth is designed to meet the needs of production cartographers using a variety of software applications. We developed Natural Earth as a convenient resource for making custom maps.
