how to tag location on map which plugin to use

Hello i want to make a website where user or anyone can share location and tag with images on google map just like tomnod. I want to use something like instagram or pinterest app for this. I want to make a website for user or anyone to tag areas which they need accessibility for disabled so others can view and fund or donate a wheelchair lift for that area etc and to inform the disabled if the area is disabled friendly

Hope you can help with solution .
