PostGIS with some middleware and Leaflet is more than enough. The rest is integration of data.
OSM is for data, the visualisation lib that is easiest to get right is the Leaflet. You can of course also use OpenLayers.
Most layers on this project are perhaps freely available already. If you need to map objects - QGIS is a free tool and there are plenty of segmentation algos. MMQGIS can geocode datapoints scratched from APIfy.
Btw, those who downvoted my comment must be really ignorant about the area of GIS. I find no other explainarion.
