About IRHB maps
By Henrik Thiil Nielsen, 2020-12-22. Revised by Henrik Thiil Nielsen, 2020-12-22.
The interactive maps on IRHB come in two flavours:
- maps on pages concerned with a specific item of information, for example Robin Hood (Buckingham)
- maps on landing pages, for example Leicestershire place-names.
What you can do with maps of the type listed in #1 you can also do with those of the second type. However, the latter have some additional interactive features.
Things you can do with both types of map
All the interactive maps support the following.
- Moving the map view
- Click and hold down the left mouse button (or press with your finger) and move the map view to the desired location.
- Zooming
- If you are using a wheel mouse, turn the wheel forward to zoom in, backward to zoom out. Otherwise click or press the plus sign in the top-left corner to zoom in, click or press the minus sign below the plus sign to zoom out.
- Full screen view
- Click or tap the third control top-left to enter fullscreen view. Click or tap the same control to return to normal view.
- Choose mapping service
- Clicking or tapping the control if the top-right corner lets you choose between mapping services. Currently the following are supported:
- Stamen.Terrain. A terrain map.
- NLS. The Ordnance Survey's 1" series of maps, hosted at the National Library of Scotland's map subsite
- OpenStreetMap. The default map.
Things you can do on item maps
At present, if you click a green marker on an item map, say the map of Robin Hood (Buckingham), a small box with the name of the locality or a brief text is displayed.
Things you can do on landing page maps
Just below maps on landing pages in the place-names section are three buttons, labelled respectively Overview, Navigation, and Choropleths. Unless the view associated with a given button is already displayed, clicking or tapping any of these takes you to the corresponding map view. Each is dealt with separately below. What is said under Overview below applies also to the maps on landing pages in the festivals section, where there are as yet no navigation maps or choropleths.
Overview
This is the standard view. All that has been stated above, except that under "Things you can do on item maps", applies here. In addition you can do the following:
Choropleths
The choropleths can be used in exactly the same way as the navigation maps, though this is not their main purpose. For a detailed discussion of them, the information they provide, the data on which this is based, and their interactive features see Place-name choropleths.
At present choropleths are found only on landing pages in the place-names section.
