Nationalisation, security of mining tenure and survey diagrams
by  Prof. Fred Cawood, University of the Witwatersrand
        
Fred CawoodMine nationalisation has emerged as one of the major threats to the future and sustainability of the South African minerals sector. Because mineral resources are depletable, we have only one opportunity to make the most of each mineral resource. Government must understand the need for stability of terms and security of tenure...

Pride of profession
by Roger Fisher, Professional Land Surveyor
  
Roger FisherPractical evidence of pride within our profession came to my notice years ago during a visit to the Cape Town Deeds Office in search of some title information.

The South African measurement system and its origin
by Tomasz Zakiewicz, Chief Directorate: National Geo-spatial Information
  
The history of the South African measurement system is, without doubt, somewhat confusing, as is the relationship between old South African units of length, English measure, and the legal and international metre. The English and metric systems have influenced the establishment of the "commercial" Cape units, and, also, of the unit of the Geodetic Survey of South Africa.... (more)
Institutionalising a GSDI at the CSIR
by Heidi van Deventer, CSIR

 

Institutionalising a Geospatial Data Infrastructure (GSDI) was a major watershed for research data management at the Council for Scientific and Industrial Research (CSIR). For the first time in the CSIR's history, the ICT department took over the management and maintenance of research-related software and data. For the first time, geospatial data was related to publication outputs... (more)

Mapping Earth's gravity field
Information from European Space Agency

 

The European Space Agency's (ESA) Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite has reached its ambitious goal of mapping Earth's gravity with unprecedented precision. In two short years, the sophisticated satellite has collected the measurements needed to record the "geoid" reference shape of our planet... (more
SumbandilaSat provides valuable imagery
by Jan-Albert Koekemoer, SunSpace et al

 

SumbandilaSat is living up to its Venda name as it "leads the way" in providing SA entities with valuable satellite imagery at no cost, despite earlier technical setbacks. During August and September 2010 SumbandilaSat acquired five high resolution images of the south-western part of the Krugerl Park area where the CSIR and SANParks Scientific Services are... (more

3D mobile mapping transforms infrastructure management
by Lance Nel, TGIS

 

Combining 3D mobile mapping, integrated information systems for municipalities and mobile GIS/data logging will change the way that municipalities manage infrastructure. Working in conjunction with each other, these technologies enable efficient use of time, reduction of unnecessary expenditure, and will help to ensure that all South Africans have access to reliable services...
