Find by Place - with Marker Pin - Help

You can use this application to search and view all of our online maps. This search process complements our main Find by Place - with Bounding Boxes application that allows searching showing the boundaries of map sheets. Our Explore Georeferenced Maps application allows a selection of seamless mosaics to be viewed.

Main search process

Move the marker to your point of interest. The maps covering the marker location appear in the Results on the right. Click on the map image thumbnails to view the maps.

Find by Place interface with instructions

You can also double-click on the map to move the marker to that point.

All of our online maps are searched in this application.

Gazetteer

You can search by address, place name, or postcode to zoom the map to your location of interest. The gazetteer searches the Google Maps Places API.

Limit results by date range

Change the date range sliders in the left-hand panel to limit the maps returned to a particular span of years.

Limit results by scale

By default, the maps returned are based on the scale of your main map. When zoomed out, covering a wider geographic area, less detailed maps are returned. When zoomed in, covering a smaller geographic area, more detailed maps are returned. To change this to return all maps, regardless of the zoom level, change the Scales of returned maps to 'All scales' in the left-hand panel.

Linking to the viewer

The URL in your web browser address bar changes dynamically as you zoom and pan the map, and when you change the position of the marker or date range. You may copy or bookmark the URL in your web browser address bar to save the current viewer location and returned maps.

Application

This application uses GeoServer and the Google Maps API.

We have released the code behind this viewer on Github for onward use. We hope that other libraries, archives and institutions may benefit from the code in making available their geographical collections.
