The United Nations' Sustainable Development Goals emphasize the importance of evidence-based decision-making. This is a call for Earth scientists to contribute directly to the health, prosperity and well-being of all people.
Satellite and Arial Photography
In the fields of satellite imagery and aerial photography, the geospatial community has a myriad of choice with respect to sensors, resolutions, revisit times and capabilities in terms of imagery. Within the community, the ability to extract information and knowledge from these images seems to be lagging behind as most applications stop at using the imagery as a source of “line mapping” or even more simplistically an image backdrop or pretty picture.

Solar can also bring important benefits to people even if it is just a few watts at a time. The inspiration to bring solar power to
Africans who live off the grid came to Xavier Helgesen a few years ago.
On a business trip to Malawi, he decided to spend the night in a small city with 30,000 inhabitants. He was amazed to see the entire city was dark after the sun went down. People carried kerosene lamps at night. When a family invited him to dinner, they all huddled around one dim indoor light.

Our Sustainability Hero of the Week is Geoscientist, Stuart Martin. He specialises in the
extraction of information from satellite imagery and aerial photography. This information is modelled and integrated with other data sources to
provide valuable business intelligence. Tune in to the iStart2 Show and find out how Stuart Martin from GeoTerra Image makes his contribution to creating a more sustainable world.
Keitu Gwangwa & Pierre du Toit host the iStart2 Show on Thursdays at
17h30. Radio Today broadcasts on 1485 MW (AM) in greater Johannesburg
and countrywide on #DStv audio channel 869.
