About Nokia Here maps Function in HANA

Dear all,

Where can I find some introduction or example project about the NOKIA here maps function in HANA. I saw a similar demo in SAP Truck and a demo video on youtube(Spatial Analytics Demo on SAP HANA using Nokia & ESRI Maps - YouTube) which are nearly the same with my working project now.

There aren't much detailed information like add an marker, draw an circle to define an area and show the status in this area.

I tried to use google maps  V3. It's very useful with detailed samples. But it has a limit for free api key.

Thanks a lot !

Shu.
