There are two formats for viewing "slideshows" of selected Google 360 degree Panoramas.
The first format is "on ice" for this App until we are able to include a proper selection of Trekkers (so keep those emails going), but here is an example from The Cotswold Way App where 90 Thumbnails (five walks) can be selected for the Panorama to appear below.
You can step through the 18 Panos (for each Walk) which are spaced about 500 yards apart to get a very good pictorial idea of the particulars of the walk, or you can "break-out" at any stage to examine an area in more detail.
Secondly, by using the SatNav route (see above) there is an option to examine "DETAILS" (rather than "Send directions to your phone"). Once selected the system steps through the same "turn by turn" instructions sent to your phone and in some cases shows you a small image (marked as Street View) from the Pano at the turn.
The image above shows an example of these instructions and this one reads (on the Left) "Walk east on ......." and a Blue Arrow is shown on the Map on the Right.
You can either keep stepping on the Left or click on the Street View Image to "break-out" to a split screen as shown below.
Now you can Select any Pano you wish along the Blue Dots or use the Arrows etc in the upper section to advance along the route or examine in more detail.
We all know that one can get to a similar "Split Screen" directly in Google Maps but please be warned of "the needle in the blue haystack" issue mentioned above and in Central London the StreetViews are very close together (even before we might get Trekkers).
So the Blue Dots of the SatNav route provide a very good reason for including SatNav in an app to use at the Planning Stage, even if there is a problem with "coverage on the trail".
