Lordfly writes "I'm part of an online group of local hobbyist, semi-pro, and professional photographers. I want to start an editable map that showcases interesting places to shoot photos — parks, old buildings, interesting infrastructure, etc. Ideally I'd like to be able to tag/organize the markers (public/private property), as well as add example photos for each location to give people an idea of what the place looks like.
I've used the Google Maps 'Create a Map' feature, but have found that sharing for other users to see/edit is a bit ... off. Also, given Google's propensity for dropping features without much pretext, it makes me wary to sink time and effort into a possibly ephemeral map. It does most of what I'm looking for it to do, but are there more robust alternatives out there I'm not finding?"
