Tutorial to create a mosaic map service

Portablemaps presents us one of the best tutorials I've seen, made to pure javascript and html; The most interesting thing is that it presents the final product, but it shows how it is done step by step ... all from a single click and without being a depth tutorial, rather for people who learn easily by seeing how it is done.

It is best that you let it load, and play with the icons of the vertical panels, the zoom and then consider that in the left frame is the explanation how to do it ... it is worth it.

Among the contents of the left menu are:
