Sort Photos by Season

I suggest a feature for the following:

1. The photos tab for a trail should classify photos by season.
2. If the photo's metadata contains a date, that should be used for classification.
3. If the photo's metadata does not contain a date, a machine learning classifier trained on photos with known dates in the area of the trail should be used to estimate the date.
4. Users should be able to scan the photos with a calendar at the top of the page.
5. The calendar should be two color coded bars to indicate the season and amount of greenery/foliage in the area, which should be derived from the photos.
6. Satellite imagery could be used to augment the above color coded bars.
7. If possible, average rain and water levels could be included as bars as well.

Something like that would be interesting to help scan trails that have thousands of photos. Currently, I am planning a trip and I would like to go somewhere with nice green trails.
