Countries.geojson Download: A Guide for Geospatial Data Enthusiasts
If you are interested in working with geospatial data, you may have heard of GeoJSON, a popular format for encoding geographic features and their attributes. GeoJSON is based on JSON, a lightweight and easy-to-read data interchange format. GeoJSON can represent points, lines, polygons, and collections of these types, as well as non-spatial properties associated with them. GeoJSON is widely used in many GIS technologies and services, such as web mapping, data visualization, and spatial analysis.

One of the most common types of GeoJSON data is countries.geojson, which contains the boundaries and names of all the countries in the world. Countries.geojson files are useful for creating interactive maps, performing spatial queries, and analyzing global patterns and trends. In this article, we will show you how to download countries.geojson files from different sources, and how to use them in various GIS applications.
How to Download Countries.geojson Files from Different Websites
There are many websites that provide GeoJSON data for countries, either as standalone files or as part of larger datasets. Here are some examples of websites where you can download countries.geojson files:
GeoJSON Maps of the globe
This website allows you to create custom vector maps based on GeoJSON data. You can select your countries or regions of interest, choose the resolution and format of your map, and download it as a GeoJSON file. You can also view your map on an interactive Leaflet map. The website uses data from Natural Earth, a community project that provides free vector and raster map data.
DataHub
DataHub is a platform that provides access to various open datasets, including geospatial data. One of the datasets available on DataHub is geo-countries, which contains geojson polygons for all the world's countries. You can download the entire dataset as a zip file, or browse and download individual country files as geojson files. The dataset also provides metadata and documentation for each country.
GitHub
GitHub is a platform for hosting and collaborating on code and data projects. Many GitHub repositories contain GeoJSON data for countries, either as part of larger projects or as standalone resources. One example is the geo-countries repository, which is maintained by the Open Knowledge Foundation. This repository provides geojson polygons for all the world's countries, along with their names and ISO codes. You can clone or download the repository as a zip file, or view and download individual country files as geojson files.
How to Use Countries.geojson Files in Various GIS Applications
Once you have downloaded your countries.geojson files, you can use them in various GIS applications to create maps, perform spatial analysis, and explore geospatial data. Here are some examples of GIS applications that support GeoJSON data:
Leaflet
Leaflet is an open-source JavaScript library for creating mobile-friendly interactive maps. Leaflet has a built-in support for GeoJSON data, which means you can easily add GeoJSON layers to your map and style them according to your needs. You can also interact with your GeoJSON features using popups, tooltips, events, and filters.
ArcGIS Online
ArcGIS Online is a cloud-based platform that provides mapping and analysis tools for geospatial data. ArcGIS Online supports GeoJSON data as an item type, which means you can add GeoJSON files to your content and share them with others. You can also publish hosted feature layers from GeoJSON files, which allow you to edit, analyze, and visualize your GeoJSON features online.
QGIS
QGIS is an open-source desktop GIS application that offers a variety of tools and plugins for working with geospatial data. QGIS can read and write GeoJSON files, which means you can import and export GeoJSON layers to and from your project. You can also use QGIS to convert other vector formats to GeoJSON, or vice versa. QGIS also supports various plugins that enhance the functionality of GeoJSON data, such as the QuickMapServices plugin, which allows you to add basemaps from various web services to your map.
