Spatial data infrastructure - what spatial data infrastructure
by Clare van Zwieten, EE Publishers
Clare van ZwietenGIS is integral to government operations and yet here in SA, treasure troves of GIS data lie hidden in silo structures while various government departments and local municipalities blow their budgets hiring consultants to provide them with data that is actually freely available to them, if only they knew it was available and how to access it...

Frustrated wage negotiations halt new land transactions
by Gavin Lloyd, SAGI
Gavin Lloyd Several critical surveyor-general offices have effectively ceased to function and others are on a go-slow due to the failure of protracted negotiations about wages and staff levels over the last year within the Department of Rural Development and Land Reform.

Rethinking our unsustainable housing and urban design policies
by Gavin Lloyd, Lloyd and Hill

A radically new approach to low cost housing is needed that recognises the limited amount of accessible land available within our cities, that addresses the multitude of social ills carried over from our past, that delivers within a recession and, importantly, that factors in an evolutionary housing path to be followed from our current limited capacity towards more advanced solutions that will be possible in 30 years time...

Cadastres and climate change
by Prof. Paul van der Molen, Kadaster International

Land registers and cadastres have to extend their function beyond the conventional use for land markets and land taxation. The data comprised in the land information systems are also useful to facilitate government policy on adapting to and mitigating climate change. Registering new rights in the form of carbon credit titles would be feasible. With all these aspects in mind, the idealistic concept of registers and cadastres as "multi-purpose" land administration systems becomes a real possibility... (more)

Image accuracy checkpoint collection guide
by Ashley Sedorovich et al

This guide is designed to help you perform a rigorous accuracy assessment while minimising the effort to do so, by providing an overview of how to collect high-quality ground checkpoints. In this white paper you will find information on what a photogrammetry target is, what one looks like, what the dimensions are based on scale, where to place them, and how to locate ground checkpoints if a photogrammetry target is not available...

Supply chain analysis 
by Craig Gers, Solomon Risk Management

While working for a former employee, we undertook some exciting supply chain work which combined crop models, historical rainfall data, GIS, storage capacities of grain silos, road and rail networks - multi-modal transport mechanisms, producer locations, consumer locations,  market prices of the commodities (SAFEX) and crop production areas. Supply chain analysis consists of a quantitative analysis of inputs and outputs between firms, prices and value added along a supply chain through agent accounts... (more)
