Guide to map images viewer
Our maps viewer gives you:
- A resizeable window for viewing maps.
- A zoom control (top left) for enlarging (+) and reducing (-) the map image.
- An overview window (bottom right) showing the current map detail being viewed in context.
To move sideways or pan:
- Drag the image in the main image view.
To zoom in:
- Double-click the mouse.
- Use the mouse wheel (if available).
- Hold down the 'shift' key and drag the cursor to draw a specific rectangle to zoom in to.
- Hold the [Alt] and [Shift] keys, and drag with your cursor (ie. hold the left-hand mouse button down and drag) to rotate. Refresh the page to return to the default rotation.
To print / capture screen
- By default, choosing the 'Print' option / Ctrl + P in most web browsers will result in the current map view extending across your default page for printing or saving what you can see on screen.
- The Print PDF tab to the lower left will create a default A4 landscape PDF of your current map view, usually including an NLS logo and details of the map and its URL.
- In both cases if you alter your window aspect ratio, then the map will fill different overall extents. To make the logo and map details disappear, increase the height or reduce the width of your current browser window.
- If you require a print of a large map in detail, or of an area larger than your screen in detail, then you will need to Order this map.
To link to this view:
- By default, the standard URL for each map (ie. http://maps.nls.uk/view/[map ID] ) presents the initial view of the whole map on the screen.
- To save or send a link to a more specific part of the map, select the Link to this view tab, and a suffix will be added to the standard URL. This includes zoom=, lat= and lon= parameters, which relate to the original image and pixel dimensions.
This viewer is a customised version of the open source IIIF Viewer for OpenLayers 3, and is compatible with all modern standards-compliant web browsers: Internet Explorer 10+, Firefox 3+, Chrome, Safari 3+, and Opera. Viewing but not printing is also possible in Internet Explorer 9.
