If you want to use GPS location on your web application, all of the services are supported SSL completely. It's a little hard so I created a location proxy service "whereami". Just link to "https://code4fukui.github.io/whereami/" with your return URL after hash!
We "team 198" updated our application for better your trip experience "CHIE TO BAA". You can use any location in Japan (using 5 star sight seeing opendata on odp). And we post to opendata contest "LOD challenge 2016"!
