Data Points collected on InfoMap.Travel are grouped in two major categories: ELEMENT and LOCATION. An Element data point is related to a specific physical object while a LOCATION data point presents information for a Town, Village, City, Island etc.
The sources are different depending on the type of Data Point. Wikipedia pages, publicly available boards at the location, tourism authority info, authoritative blogs, news and reportage from major networks, books. The authoritativeness and reliability of the source is something taken very seriously.
