Changes in this release:
Brian Willson writes, “More data has been added from our band of surveyors (special thanks for all their hard work). Corrections made as reported from feedback.
To support the growing numbers of users on low-resolution devices, I have reduced the size of the spot depths, navigation marks and other icons. Users of high-resolution devices may need to over zoom their display to compensate if your app supports it. The overview zoom levels now show the navigation marks to aid with navigating the broad loughs whilst zoomed a long way out.
There are high-resolution images of a selection of interesting Islands on the two most detailed zoom levels of the charts. (See Holy Island on Lough Derg as an example)
The Grand Canal and the Barrow have had extensive makeovers due to much work/contribution this summer and there is more to come, plus updates to the Royal next year.
All this work and new data has increased the size of the charts so I have created some options to help those who do not need the whole set of data.
As always, we welcome your feedback and constructive criticism for improving the charts.”
The latest release of the CSIG charts is now available to all Beta Testers.
Brian Willson writes
“There has been a lot of new data added that has been tirelessly collected by our small but growing band of surveyors. If you want to help and speed up our data collection then please get in touch. The more surveyors we have the faster the charts get populated.”
All outstanding feedback issues that have been passed to Brian are included in this release. This version has new file formats to make the charts much easier to use.
Details of the new release are included in the e-mail sent to all CSIG members.
On February 26th, the B7 Version of the CSIG Charts was released to all Beta Testers.
Brian Willson writes
“I have continued to refine the spot depth algorithms to allow me to increase the size of the spot depths in the charts (by removing redundant spot depths) without losing critical data. I have enlarged the size of the post navigation marks on the Shannon.
There is now an overview of the Barrow Navigation and I have incorporated the Royal and Grand Canals.
Just for Locus and Galileo users there are some new “Experimental” areas of Lough Neagh and the Newry Ship Canal.
There have been many other minor cosmetic changes, tweaks and corrections.
Thanks to all Beta Testers who provided feedback.”
Season’s Greetings to all our members and friends
“It has been a great year for the CSIG group. We have introduced new releases of charts, added new platforms, produced new icons, opened new areas to navigation, added many more testers, added new surveyors, upgraded the surveyors app, conducted Pilot tests with WI, released a new distribution methodology, and had great fun doing it all. Many thanks to all of you, for the support and assistance in keeping this great project alive.
Here’s to next year and another great boating and charting season.

At the end of our first year in operation, October 2012, we were delighted to report there were 27 CSIG members. At that time, some surveying and mapping was complete, IWAI Branches had started to help us financially, and as a group, we were excited and astonished at the huge task we had undertaken.
Today, two and a half years later and thanks to the support of many, we have Charts at various stages for Lough Derg, Lough Erne, Limerick, Lough Ree, Lower Shannon, the Shannon Erne Waterway and the Upper Shannon. We are currently working on the charts for the Grand and Royal Canals, the Green and Silver Route. Our membership has grown to 34 with
79 over 100 (Aug 2015) IWAI members testing the Beta 5 release.
We know IWAI members enjoy using and testing the charts produced by the CSIG and those of us involved in surveying and mapping, welcome your comments and corrections. Here is a recent example of feedback. “In a word – fantastic! ………. Particularly useful is the fact that the buoys are numbered and the depths are impressively accurate. ………. One of my favourite places is the delightful Barley Harbour. On my first visit some years ago, I was not sure of the location of the shallow area just to the NW of the approach, my props found it though! Now I look forward to regular returns to Barley with the confidence of knowing exactly where to avoid, thanks to the CSIG charting. ………. Many thanks for the extraordinary amount of time and effort you and your colleagues have dedicated to the CSIG project. For those of us who enjoy going ‘off channel’ it has opened up whole new areas to explore and enjoy with confidence.”
Come and join us, in our surveying and mapping efforts or by testing and using the Beta releases, “every little bit helps” to make the charts more accurate for all.
