Need a specific GIS software product? We have various site licensed products, meaning you can just use them and don’t have to buy a license: http://www.applications.itservices.manchester.ac.uk/list_products.php?category=gis&excludeArchived=1
Please check terms and conditions, e.g. some restrict use to on-campus or university-owned PCs only.
Of course you can use any other software you like, but you will need to obtain it yourself.
