Idea. Literary travel

Essence: the map shows geographical objects that are found in a literary work - settlements, rivers, lakes, routes of heroes, etc. The marks on the map are complemented with descriptions - fragments from the work, pictures of artists about these events, photographs, etc.
The idea itself is not new. I met with literary travels, thanks to Eugene Patarakina. Here is the material on the topic, and this is a detailed instruction for creating .
My suggestion: on the basis of online libraries, resources devoted to books ( lib.ru , Google Books , etc.) to make a service that automatically marks geo points from a large collection of books. It may look something like this . And the picture:



Technical base:

• The initial level - for the scheme “Entered query - Got a point on the map with fragments of works”, it is enough to access the search engine and transfer the search results to the map - as in my example.
• Getting information about geo-points from the resource base - for example, parsing pages and searching for matches with a base of geographic objects. Next, through the Google Maps API, put points on the map.
  

Functional:

• The link should open not just a page, but a place on a page with text from search results.
• Users should be able to vote for point-of-work, correct inaccuracies and add places that were not added automatically.
• Browse by category: “History”, “Travels”, “Biographies”, etc. As a result, we get the opportunity to see which celebrities have visited, for example, in Tallinn or to find diary authors who traveled in the Amazon jungle.
• Viewing by time fragments - as a rule, often instead of with a place, the time when the event occurred is indicated. Thus, it is possible, for example, to see what and where happened in the second half of the XIXth century. How much is this reflected in the literature and specifically in what books.
  

This service may be of interest to bookstores. Next to each description of the book we make a button “Buy” and order.

How do you like the idea? Kick, offer.
