Question

I am building an HTML5 app for an iPad and it will contain a map for basic contextual information. I need some way to cache the map offline selectively (i.e. I am going to an area that I know is without connectivity so let me cache that part of the map beforehand).

Alternatively I can render vector layers from a WebSQL repository of them and in that case how would I convert maps to vector and display these vectors in a panning map (i.e. Swap between or add too vector layers)

Thanks in advance

I know that some guys were experimenting on local storage support during OpenLayers Mobile Codesprint back in February. Here is an example of what they’ve accomplished. I recommend that you checkout jgrocha’s sandbox and take a look if what they did suits your needs.
