Firstly, the entire article reads as if it is an advertisement for the creator of the maps and the software used to produce them. Secondly, and despite the aforementioned, a wealth of information is nevertheless provided which is interesting, informative and fascinating. All that being said, the images shown are indeed stunning. The links provided are fine but do not add particularly much in terms of context, nor do they offer much in the way of further elucidation. In the main a worthwhile read which some readers might even wish to bookmark for future reference.
