I've been experimenting a lot of late amongst the Leaflet-IIIF plug-in. The plug-in allows you lot to display IIIF manifests inwards Leaflet maps. This map of Van Gogh's Self-Portrait Dedicated to Gauguin shows how you lot tin purpose the plug-in to pan & zoom to a greater extent than or less an IIIF manifest. While this Compendium of Victorian Map Games shows how you lot tin charge dissimilar manifest URLs into the same Leaflet map.
One of the master copy advantages of using Leaflet to display IIIF manifests is that you lot tin switch betwixt a map in addition to an IIIF manifest amongst some ease. In other words Leaflet tin travel used to demo the place of geo-tagged images in addition to supply an interface inwards which you lot tin pan & zoom to a greater extent than or less these really same images. You tin become a amend thought yesteryear looking at this demo map of Dublin 1916.
This map uses a position out of postcards created later on the 1916 Rising inwards Dublin. These postcards are held yesteryear the UCD Digital Library. The map shows the place depicted inwards each of the images. If you lot click on a marking hence you lot tin persuasion the postcard selected in addition to pan & zoom to a greater extent than or less the image.
Switching betwixt a basemap map layer in addition to an IIIF manifest is non every bit straightforward every bit you lot mightiness think. The argue for this is that the map in addition to the IIIF manifest purpose dissimilar map projections. Therefore you lot take away to alter the map projection every fourth dimension you lot switch betwixt a manifest in addition to the map.
