The QGIS platform is an open source GIS platform run by contributors from all over the world. Before the advent of QGIS, similar GiS software packages have been proprietary like MapInfo and Esri ArcGIS. These proprietary packages are expensive and mostly were targeted at corporate users. If the Americans and Europeans mourn about the cost of acquiring these proprietary softwares then we in Nigeria and Africa as a whole are just about at our wits end.
The long term effect of these inaccessibility to affordable GIS software packages has been a software market awash with faulty, half complete, unstable and pirated copies of arcgis and mapinfo. Of course, one should forget the calm group that always managing through on trial versions.
