I'm not native English Speaker and I'm a graduated student who want to have a master degree in software engineering. I have a thesis relative with "Build a WebGis for air pollution in Vietnam's capital city". But I've never any experiences with GIS. I've searched some Google, this show me that I should use MapServer, Openlayers and PostGis SQL.
Please, correct me if I'm wrong or teach me some knowledge. Thanks you for that.
