New mosaic aids in delivery by government

Fig 2The latest SPOT 5 national mosaic for 2012 has been released at an event by the South African National Space Agency (SANSA) to key stakeholders in government departments and private industry for use in addressing national requirements. 

The imagery which is collected over a period of 12 months is downloaded and processed by SANSA into the comprehensive tool which is delivered free to stakeholders who utilize this information to address issues facing South Africa, such as planning for infrastructure and housing, agriculture, water and environmental management and national census, amongst others. 

Dr Jane Olwoch, MD of SANSA Earth Observation stated, “It is a significant achievement for SANSA to be able to provide a state-of-the-art product that brings huge impact to the lives of our citizens when used by our government stakeholders.” The mosaic is made up of 485 images taken by the SPOT 5 satellite which has been processed and compiled to make up the entire map of the country. The detail within each of the tiles of the mosaic provides information of an area 60km by 60km. 


Capture, extraction and analysis of spectra: A practical course in spectrometry

Spectra advert

From the 28-30 May 2013, SANSA Earth Observation will be providing an exciting practical training course in the best practices for the capture of field spectra and how to extract and analyse information from captured spectra.  Spectroscopy is the study of the interaction between matter and radiated energy, and forms the basis of optical remote sensing.  In the field of remote sensing spectroscopic studies provides practitioners with the opportunity to study the absorbance and reflective properties of objects across different regions of the electro-magnetic spectrum (Fig 1).  Interaction between radiated energy and matter is based on physical principles and analyses of spectra provide users with the opportunity to understand more about the composition and structure of the studied objects.

SANSA, Southern Mapping Company Spectrometer Training

Spectrometer1The South African National Space Agency's (SANSA) Earth Observation directorate collaboratively hosted a Spectrometer training together with Southern Mapping Company – the Spectral Evolution instruments' African partner – on 11 February 2013 at Hartebeesthoek.

Both SANSA and Southern Mapping Company have recently acquired their own Spectral Evolution field spectrometers. A Spectral Evolution consultant was in the country to attend a conference and offered to use this opportunity to hold a training course on their spectrometers. In consultation with Spectral Evolution, the training course offer was extended to a broad audience of earth observation data users.

North West Upgrade Informal Settlement Programme Managers workshop

NW housingThe North West Provincial Government (NWPG) has been working with SANSA (CSIR's Satellite Application Centre at the time) since 2007. The main objective of the project is to collaboratively develop an informal settlements database used during the Upgrade Informal Settlement Programme (UISP). In November 2012, the Housing Delivery division approached SANSA to assist the verification of investment made in the development of Low Cost Housing units, in specific areas of interest. The process involves the use of remote sensing technology to generate information to be used in producing reports on how much, and where the housing budget is spent. At present, SANSA Earth Observation is using the latest high to very-high resolution remote sensing data to generate the required information.
