Accessible GIS Data for South Africans

IntroductionThe Vision: Open DataWhat Is Open Data?The Importance of Achieving The Vision - Why Open Data?What Is Needed to Achieve This Vision?What Is 1Map Doing to Help Realise The Vision?ConclusionWe live in a wonderful country where the sun shines most of the time and where clouds bring promise of new life. In the world of geography and maps it’s also fitting that the cloud should symbolise a new dawn, a promise of new growth. In South Africa, the pioneers of survey have left us with a legacy which is the envy of many a country. We are one of the few countries in the world that boasts a national repository where all approved survey records are saved and made available to all who require them in the execution of their work. A legacy gives you a head start, but if the next generation of visionaries do not rise to the challenge and build upon the legacy, it soon fades and becomes merely an interesting historical fact.Get price
