Kosciuszko Huts Map by Narelle Irvine, a GIS specialist. Narelle and her family have been involved with the Kosciuszko Huts Association – who maintains the old cattlemen’s huts spread throughout the national park – for many years now. When the Association wanted a web-based map showing the huts’ locations, Narelle volunteered and embarked on a self-education program to understand and use open source mapping tools (along the way learning HTML, CSS, icon design, and JavaScript using EXT.js, GeoExt.js, OpenLayers, OpenStreetMap).
