Customized HTML5 Sky Map / Area Map generator

I'd like to have one website that builds in the functionality of both of these websites: - [login to view URL] - [login to view URL] i.e. it will have a map section and a night sky section. The front end of this application will be built on Shopify - and this will be done seperate to this job. I require someone/or a team to build an intergration allowing the user to personalize both a sky-map or area map, see here: - [login to view URL] - [login to view URL] To do this - you are welcome to copy exactly what these two websites have done. This is a difficult job and I'll require someone with an indepth knowledge of HTML5, and can explain in detail how they'll do it. Please only apply for this job if you have studied both these sites and are confident you can produce a replica of both sky-map generator and the mapiful generator.
