Geographical Information Systems (GIS) data

Teaching the use of GIS software is beyond the scope of this website. Links will be provided in the "Using Data" section to training material available on the internet for using QGIS the open source software that that is referenced in the website. There is more information in the section "Open Source" on downloading the software.

QGIS can load data in a number of formats but the most common are probably "shapefiles" and spreadsheet tables. The shapefiles are loaded directly while spreadsheet tables and other formats often require some kind of formatting. Data for use in GIS analysis will be listed under the various headings along with national and subnational data. Data which does not fit into the designated categories includes the basic global national and subnational outline files, for which sources will be given below. Also given below are links to two sites which provide shapefiles  containing detailed current data from OpenStreetMaps (OSM). The OSM mapping is done by volunteers and completeness of areas mapped varies from country to country--much progress has been made recently in the mapping of developing countries.The sites selected for the various sectors provide global country-level data or at least data for a number of countries.

Geographical Border Shapefiles

Outline Maps--There are many sources of "shapefiles" which provide global, regional, national and sub-national outline maps onto which other data can be superimposed. A short selection of sources of this type of data are listed below.

WORLD BANK--The World Bank provides a range of country profile shapefile maps at World Bank Boundary Files click on the "Data and Resources" tab.

GADM--GADM provides access to country map outlines with several layers of administrative sub-divisions. Data can be downloaded country by country or the whole database can be downloaded .

Statsilk--This site provides links to country and sub-national outline shapefiles as well as outlines for individual countries, and links to other GIS resources. Click

HDX-- This United Nations data set provides shapefiles, including boundary areas and sub-administrative areas at There is a box for entering country names and other search data in the top left corner of the page.

Natural Earth-- Provides a range of global map outlines including South Sudan. Click note of caution, be sure you use the "ISO" column for codes not the "ADM" column codes.

South Sudan-- Many map collections do not include South Sudan (SSD) -- mapping for South Sudan is available at (The file name is

DIVA-GIS--Provides country level and world level shapefile outlines at Unfortunately the data is somewhat out of date and neither the global or country maps include South Sudan.

Mapcruzin--Contains links to a large number of shapefiles at The African maps do not seem to include South Sudan. Data updates appear to have ended by 2019.

Finding Shapefiles-- There are far too many sources to list. Many countries supply specialized outline shapefile maps--Canada for  example provides shapefiles for census areas and outlines of treaty boundaries for indigenous "First Nations". A search for "Zimbabwe roads shapefile" brought up 10 links.
