Please define a CSV format (easiest and most manageable IMHO) in which groups that have already done tree mapping can email in the data they have gathered. Adding them to the map or not would of course be metastudio's prerogative. But some predefined and well-articulated structure would go a long way in getting already-done survey/research opened up and incorporated.

Additional : photographs might also be part of the data. If so, they will probably already be serial-numbered, or the submitting group can do that on their end before submitting. So that photo-id becomes another column in the CSV, and then the submitters could zip the photos and share them via bulk file sharing service

Trees on OpenStreetMap.org are identified by the natural=tree key-value pair. I don't find much of more details in the OSM data, but at least they're marked with precise location and can be good starting points for people to add more details to.
One can follow these steps to extract that data.

1. Download city's OSM data from Mapzen , or country-level from Geofbrik.de.
2. Get osmfilter and osmconvert
3. Extract only trees data from the osm file using:

osmfilter pune_india.o5m --keep="natural=tree" -o=pune_tree.osm

1. To get the data in a format you can easily use, convert to CSV:

osmconvert pune_trees.osm --csv="@id @lat @lon natural" --csv-headline -o=pune_trees.csv

See here for extracting specific region data from larger OSM data.

Mission Devrai has been launched recently and can really make use of this platform. The people behind it have the network but not the tech skills. So are coping with adding the mapping to google maps only so far.

This would essentially be a feature of adding a group of trees spread over a small area (in some cases large area), that are together known locally as a sacred grove or devrai.

Example for Sacred grove: http://www.openstreetmap.org/node/3438615786

At least keep OSM and Mapbox Streets (with a user key) as an option? They're pretty straigthforward to load in leaflet.

If I'm in Mumbai then there's a bounding box set around Mumbai and I can't pin a location outside that box. But by clicking "Use Current Location" feature i'm able to get a location outside the bounding box pinned. I can then drag it around to wherever I want it.
So this seems to be a hack to break out of the bounding box.

Location search can be done in leaflet. Check this out: http://labs.easyblog.it/maps/leaflet-search/examples/nominatim.html

See here for a working example.

Clicking on the site title or "Explore Map" link on top takes you to the current city's sub-site. There's no way a person can click their way to another city.
