Hello,
today I was experiencing with my Spark to create panorama's.
Now I've made some amazing panorama's from my city centre, and I would like to publish them on Google Maps.
You know, so people can see it with that yellow Streetview guy.

Does anyone know how I can convert all photo's to 1 panorama photo, and upload this on Google Maps?

Most use MS ICE...Microsoft Image Composite Editor...it's free download

There are some restrictions (2:1 ratio for example, 10 to 100 Megapixel or something).
I used Autopano Giga for the stitching and send it to Google Drive.
Next I used the streetview app (both android and iOS) to upload the sphere.
Took 2 days to figure it all out, but it worked in the end.
Very much worth the effort!

Here is one example
