GeoHub NI is a web based platform to facilitate sharing, using and developing Geographic Information for Northern Ireland.
Over February we will be adding archive mapping dating back to 1830. When you open the GeoHub NI mapviewer click the add layer button
and use archive as your key word, then add the layer.
For best results when simply viewing the archive maps you should have one layer on at a time.
To compare modern mapping with the archive maps try moving the layer in the layer list or make it 50% transparent
