I would like to make a worldwide map highlighting ICAO EURNAT states, EASA member states and Interstate Aviation committee in different colors

To create a worldwide map highlighting ICAO EURNAT states, EASA member states, and Interstate Aviation Committee, you'll need to gather data on these entities first. ICAO EURNAT refers to the European and North Atlantic regions of the International Civil Aviation Organization. You can find a list of these states on the ICAO's official website. EASA member states are part of the European Union Aviation Safety Agency. A list of these states can be found on the EASA's official website. The Interstate Aviation Committee is an executive body that oversees civil aviation in the Commonwealth of Independent States (CIS). You can find a list of these states on the IAC's official website. Once you have this data, you can use a mapping software like ArcGIS or QGIS to create your map. You can assign different colors to each entity (ICAO EURNAT, EASA, and IAC) to distinguish them on the map.
