Georeferencing the country codes of top level domains (.pt) in Lisbon city: Spatial analysis of urban innovation

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


Internet is a global network. Individuals and companies have realized the value of location and because geographic space suffers distortions by an increasingly importance of techs, it is imperative to associate to this Internet virtual space, a physical perspective that identifies an origin, by connecting the virtual to its physical or territorial location. In this context, the country code top level domains registration (ccTLD) is very important and works like an anchor to our everyday space. So when we want to visit to the UK Google's page we go to and when you want to see the Portuguese Google page you write on your computer Therefore and due to the importance of creating a link between identity and its place of origin or to associate a name, a brand, an image or a product to a country, it is important to have a ccTLD registration. Using data provided by the National Foundation for Scientific Computing, now part of the FCT (Foundation for Science and Technology), it was possible to georeference the location of ccTLDs by Zip codes. Using spatial analysis performed by Geographical Information Systems (GIS) like clustering or hot spot analysis it was possible to analyse potential relations between ccTLDs and economic activity, old and traditional CBD and demographic variables to capture some of the urban dynamics. The aim of this paper is to map the registration of all the ccTLDs (.pt) in the municipality of Lisbon, using GIS spatial analysis to: a. Analyze the distribution of ccTLDs and its relation with economic activity in Lisbon city at parish level; b. Observe its correlation with economic activity, urban variables like traffic ways and number of companies registered by parish; c. Identify hot spots and clusters and find spatial patterns; d. Identify emerging business areas within the city.
