About QGIS

QGIS is the leading Free and Open Source Desktop GIS. It allows you to collect, store, manage, visualize, export, analyse and map spatial data. The QGIS project is under very active development by an enthusiastic and engaged developer community with good mechanisms for help via stack exchange, mailing lists and (optionally) through a global network of commercial support providers.

Using MapGenie in QGIS

Some Ordnance Survey Ireland mapping series are available via a Web Map Service. A WMS is a standard protocol developed by the Open Geospatial Consortium for serving georeferenced map images over the internet. You will need a list of MapGenie links and username and password to use this service which allows you view Ordnance Survey maps in QGIS.

To request username / password details please submit this online request form. This service is only available for UCD staff and students.

Free Open Source GIS Module - Learning about GIS and How to Use QGIS

This GIS module is part of a collaborative project funded by Irish Aid, led by Dr Christine Bonnin (UCD Geography), Dr Nguyen Thi Minh Tien (Hanoi University) and Dr Truong Tuyet (Thai Nguyen University) through the Vietnam Ireland Bilateral Education Exchange (VIBE) programme.

The aim of the project is to support capacity building to address the critical global challenge of climate change through Ireland-Vietnam university linkages between the three partnering universities: UCD, Hanoi University and Thai Nguyen University.

This online, free open source QGIS module was created as part of this collaboration. It is based on and incorporates case studies and examples form the Vietnam context and is currently being used by the partner universities to support climate change and sustainable development education and research.
