Features Tab

Monuments Feature


Areas showing townlands by parish


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.

You can now select categories of Monuments
and Townlands grouped by their civil parishes.

Click on the arrow beside Monuments and select one or more category of monument.
Folders can also be opened and closed by doubleclicking on the folder name.


The map will then show the distribution of that
monument type. Click on any monument to be
brought to its dedicated web page.

Click on the map above to see an example in action.

The same can be done for the Townlands by Civil Parishes.

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.



The townland area layers include the option to look only at the townlands of (a) selected parish(es), to change opacity and color, and the ability to access place data by selecting a townland area. Click on the arrow to see the list of Townlands by Civil Parishes so as to select one or more townlands.

Clare GenMaps - a guide to basic functions
intro map

The Clare GenMaps utilise the ESRI ArcGIS API, allowing ESRI, Bing and Open Street Maps to be overlaid with historical maps of Clare from 1842. The system uses many of the same controls as our GMaps system which uses Google Maps. This new system allows us to represent surname distribution from the 1820s Tithes, 1855 Griffiiths and 1901 Census datasets as interactive heatmaps linked to the extensive data on our website.

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 Bing Maps roads overlay (check box)
- optional place layers (left panel)
- optional surnames 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 Bing standard maps: Roads, Satellite, Satellite with Labels; or Open Street Map; or an ESRI map: Roads, Ocean, Satellite, Topography, Terrain; 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
  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 1842 Lahinch High Zoom - shows the town at high res.
The overlay check box becomes activated when an overlay is in use and clicking on the activated check box removes the overlay.

The Help button brings you to the Help page.


zoom in and out slider



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.

When you select one of the Areas Features (Townlands or Townlands by Civil Parishes) you can change the zoom level, opacity and style using the slider illustrated below.

Data sources
Select for each of the three data sources:
1901 Census - Names every person present in the county on census night;
1852/1855 Griffith's Valuation – Names all ratepayers in the county;
1820s-1840s Tithe Applotments – Names all tithe payers in the county, excluding the towns and villages.

Note that the Tithes are marked by (centred on) parish rather than townland, as the tithes don’t use the ‘standard’ townlands which were established in the 1840s.

Related Places



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 you 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.
