Publishing online with CartoDB
CartoDB is the name of an incredible stack of open source tools to make dynamic maps on the web.
CartoDB was developed by Vizzuality and they provide a CartoDB up and running that we can use for free (small maps).
To do these exercises, we will create a free account on CartoDB and use it to publish one simple map on the web.
For this exercise we need to create a new shapefile, with the hotels registered in OSM, in the Beijing municipality.
Create the shapefile, making sure that you use the EPSG:4326 and the UTF-8 encoding. Afterwards, create a unique hotel.zip compress file, containing the files of that shapefile.
