This demonstration application uses OpenLayers 3.14, a JQuery UI transparency slider and MapTiler georeferenced mosaics to form a viewer for Thomas Annan photographs of Glasgow.
The locations of the photographs are shown using GeoJSON sets of points, and on selection, Bootstrap Popovers show a thumbnail image and text.
The URL of the application changes dynamically to show the particular zoom level and centre of the map, as well as if a place is selected. You can save this specific URL to return to a specific map view or selected place.
