Hi, I would like to build a simple website to store pdf documents on an OSM background. The idea is simply that there are clickable dots on the map. When you click on a dot the map you can select a pdf. I would be thankful if I can get some advice on where to start. I’d prefer to build it with open source components. Also I’m a complete noob on web development.
Hi and welcome to OSM and the forum
There are several toolkits available to embed OSM-Maps in a website: https://wiki.openstreetmap.org/wiki/Deploying_your_own_Slippy_Map
These toolkits sometimes offer functions to display markers in a separate layer on top of the Map. Depending on the toolkit you can add a link (e.g. to a PDF-document) to the marker.
