Clare GMaps - based on the maps and controls of Google Maps

The Clare GMaps are based on the Google Map system, allowing Google Maps to be overlaid with historical maps of Clare from 1842. The system uses many of the same controls as Google Maps.

The map display is organised by layers:
- a base map at the bottom (1st drop down box)
- an optional overlay map (2nd drop down box)
- an optional Google Maps roads overlay (check box)
- optional place layers (left panel)

Looking at the menu bar from left to right:

		1st drop down box (Change map) The main map can be one of the Google standard maps - Google Map, Satellite, Terrain or Hybrid - or an Ordnance Survey map of County Clare from 1842 – either an overview map or the detailed 6 six-inch maps can be viewed, depending on the level of zoom used.
		2nd drop down box (Choose overlay) The following maps may be overlaid over the base map: The Ordnance Survey 1842 overview map of Clare; The Ordnance Survey 1842 six-inch maps of Clare. The overlay check box becomes activated when an overlay is in use and clicking on the activated check box removes the overlay.
		The image on the left shows a Satellite view selected from the first drop down box.
		The next image on the left shows the same area with the 1842 O.S. 6" map overlayed on the satellite view. The slider allows you to regulate the opacity of the overlay.
		Ticking the ‘Show roads’ box activates the Google Maps road overlay; The Clare button allows you to see the entire county; The < and > buttons return you back to the previous view, and forward again. This operates like the Back and Forward buttons on a web browser. The remove marker button allows you to remove a search result marker; The Help button brings you to the help page.
		To zoom in and out you can use either the slider in the map window, or the one at the bottom of the page, which shows a zoom range (in green). You can also double click on a map to zoom in, or use the mouse wheel.
		Features Tab On the left hand side, select the Features tab and tick whichever features you want marked. Features include geographical units and archaeological monuments. Because of their large number, enclosures, e.g. ringforts, are treated as a separate category. The slider at the bottom of the page needs to be within the green zoom range in order to see the feature you have selected. You can also move the slider to zoom into a map.
		Browse Tab If you want to see a particular feature, click on the Browse tab and select a category from the drop down menu. Select whichever name you are interested from the browse box. Clicking on the interactive marker for any item will open up the item’s data display in the panel on the right. Links associated with a place can be viewed in 3 ways: in directory/tree, in a sortable table with resizable columns or as a categorised bullet list. All web pages will be shown in new web browser windows. If you want to know the address before clicking on a link look at the tooltips.
		Related Places The Related Places table lists related places. For example you can go from a parish to one of its townlands and vice versa. This panel shows the relationships between the features and allows to navigate around them, for example from a parish to a Townland, to one of the monuments in that townland. Places looked at All places for which you opened the data display will be listed here in descending order. A click on an entry will take you back to that place. You can also resize the columns and change their sorting order. To see the Places Looked At click on the in the top right of Related Places panel.
		Resizing panels The system is laid out in 4 panels, which can be resized by dragging the white borders between them: - the left panel contains tabs to activate place markers - the central top panel controls the main map display - the central panel contains the map and the zoom / navigation controls - the right panel shows data listed for a selected place marker

Map view URL extension.
You can pick up from the address bar an extended URL that allows you to re-open the map system with the current "map view".

A "map view" is defined by the (possible) following elements:
- (center) map position
- zoom level
- selected map
- selection of an overlay
- the overlay's opacity
- selection of the "roads" layer
- selections of place layers

A map view does NOT include,
- a search / browse selection
- the display of a search result
- the selection of a map marker
- the display in the right panel
- the "Places looked at" history
