CSIG – Charts Special Interest Group

Welcome to the CSIG website.

Members of the Charts Special Interest Group (CSIG) are working together to deliver a new set of charts for the rivers, lakes and canals of Ireland with the aim of making the waterways safer and more enjoyable for everyone.  Achieving this goal involves carrying out depth surveys, analysing data, adding location knowledge and then producing electronic charts from the resulting information.

The CSIG is a cooperative of members from all branches of the Inland Waterways Association of Ireland (IWAI).  The CSIG also collaborates with others who are interested in what we are doing, including archaeologists, historians, rescue services, sub-aqua groups, leisure users and communities along the waterways.

Work began with one small team in 2011 and has since expanded to include several teams surveying different waterways or gathering information. The diverse skills required are passed on to new members at training and one-to-one practical sessions. Finance to underwrite this endeavour comes from our members and from several branches of the IWAI. 

We are now commencing our sixth year of what we envision as a ten-year programme and over the past couple of years, we have released several Beta versions of the charts to our Test Group.  The charts now cover the Shannon, the Ernes, the Grand and Royal Canals, Lough Neagh, the Newry Ship Canal, and the Rivers Barrow, Nore and Suir.
