|Probable bed bug infestations in Manhattan|
Frankly, there aren't enough mobile apps using WhirlyGlobe-Maply and CartoDB. So I wrote a tutorial.
We've got a brand new set of tutorials up on the brand new WhirlyGlobe-Maply web site. They'll run you through setup all the way to vector selection and beyond.
The CartoDB Tutorial is one of the cool ones. We use a MaplyQuadPagingLayer to fetch New York PLUTO data for Manhattan.
The paging layer does the dirty work of figuring out which tiles are visible. We add a little code to fetch the data in a given tile and then display it. The toolkit does the rest.
It wasn't all that hard to put this together. If you know CartoDB, you won't have much trouble using WG-Maply. If you know WG-Maply, adding the CartoDB piece is a cinch.
I'd like to see more CartoDB based mobile apps out there. Don't make me write them all myself.
