Idea

The weight and the travel freedom attached to a passport vary drastically across nationalities. International visa-regulations are very complex and often non-transparent. They reflect the economical and geopolitical situations as well as the relationships of countries.

This project aims to cast some light on these structures. The default Visa-free destinations mode shows a choropleth map, which is shaded based on the number of destination countries/territories an individual of a certain nationality can travel to without a visa or with visa on arrival.

In order to display the visa regulations for a certain nationality, the source country/territory can be intuitively selected by clicking/tapping the map, via the live search field or by choosing it from the country list. In the Visa-free sources mode, you can alternatively explore the number of countries/territories whose nationals can enter a specific country without a visa or with visa on arrival. The GDP and population modes are added for reference. Other modes can be implemented in the future.

For certain passport holders like certain special types of british nationalities it can be more complicated. For this visualization, some simplifications had to be made, ie. only the most common citizenships are used as a data reference.

Source Code

The source code of this project is available on GitHub: https://github.com/markuslerner/travelscope

When I started coding in 2014, I used jQuery and jquery-UI for all the interactions and UI updates. Nowadays I would rather use a libray like React for that.

Design & technology

This single page web application features a responsive design which works across browsers, platforms and screen sizes. Since WebGL is now supported by iOS, it performs well on recent iOS devices running iOS 8+. Recent Android versions are also supported.

One of the main goals was to be able to render the map in real-time, so that live transformations (spherical to flat) are possible. To achieve this, the powerful Three.js library and its WebGLRenderer are used for display of the map. To keep the map reponsive and save computing power, the map is created as one large BufferGeometry object. The map data are sourced from Natural Earth Data, then converted to Geo JSON format and simplified to reduce it's complexity. It is loaded with D3.js and then transformed to be used in Three.js.
