Sample datasets

Some basic information about our data aiming to be a part of examples introduced in this documentation. This section presents two sample datasets.

The first one :ref:`dataset-natural-earth` has been original created by GIS.lab developers and later adopted by Gisquick project. Later, the second dataset :ref:`dataset-prague` was developed for specific needs of Gisquick publishing platform.

Natural earth

Database natural-earth.sqlite. Available online from GitHub repository or directly as zip file.

Data source

The data is sourced from Natural Earth dataset. It is a public domain map dataset available at 1:10 million, 1:50 million, and 1:110 million map scales. It is free for use in any type of project. Dataset was built through a collaboration of many volunteers, it is supported by NACIS - North American Cartographic Information Society and contains a series of vector and raster data. With Natural Earth one can make a variety of maps with all commonly used cartography and GIS software.

Coordinate systems

All Natural Earth data use the Geographic coordinate system WGS84 (EPSG:4326).

Format and other key features

Natural Earth Vector comes in Esri Shapefile format. Character encoding is Windows-1252. Vector features include name attributes and bounding box extent. Natural Earth Raster comes in TIFF format with a TFW world file.

Natural Earth is very useful collection of data. Most of their attributes are equally important for map-making. They contain embedded feature names, which are ranked by relative importance. Other attributes facilitate faster map production, such as width attributes assigned to river segments for creating tapers, etc.
