[OSGeo-Discuss] Anyone know GPU programming?

[Pierre Abbat]

Two months ago, I asked about GPU programming for PerfectTIN. I now have the 
routine, which I'd like implemented in GPU, working. It takes a block of dots, 
all in one triangle, computes the difference in elevation between the dots and 
the triangle, computes how much moving the corners of the triangle up or down 
would affect the previous figure, does some matrix arithmetic, and produces a 
small square matrix and a small column vector as results. The code is in 
adjelev.cpp in https://github.com/phma/perfecttin .

I am about to change the sequence of block sizes. Among other things, it will 
make most of the block sizes multiples of 256, which should avoid waste when 
using the GPU to compute.

[OSGeo-Discuss] Ethics of Digital Feudalism in Location Data in Agriculture

[Suchith Anand]

Dear colleagues,


Agriculture is an important source of livelihood for millions of small holder 
farmers globally. Digital technologies  plays a crucial role in promoting 
agricultural productivity, improving rural livelihoods, and increasing small 
holder farmer incomes.   Smallholder farmers manage over 80 percent of the 
world’s estimated 500 million farms, providing over 80 percent of the food 
consumed across the developing world, and contributing significantly to poverty 
reduction and food security.


With personal data fast becoming the world’s most valuable commodity, more 
research needs to be done into the rise of Digital Feudalism and its societal 
impacts.


Do small holder farmers really benefit equally, or even at all, from the 
benefits of data sharing?

Do all stakeholders in the agricultural sector have the same access and control 
to these insights?

How can we develop and empower ICT capacity for small holder farmers, farmer 
cooperatives  etc to help reduce digital feudalism?


GODAN  article on  Ethical dimensions of Digital Feudalism in Agriculture might 
be of interest. Details at 
https://www.godan.info/news/ethical-dimensions-digital-feudalism-agriculture


We welcome all interested colleagues to  join the GODAN Data Rights and 
Responsible Data Working Group [1] and share ideas for the Agriculture Data 
Code of Conduct [2].


With  the rise of Digital Feudalism and  its impacts on Location data, it 
raises many ethical questions. I am now working on an article  looking into 
Ethics of Digital Feudalism in Location Data in Agriculture.


Are there any examples of guidelines or code of conduct for mobile applications 
collecting location data in Agriculture. Are there any journal publications or 
studies in this area.  If so, please email me the publication details so I can 
learn more and  reference them in my article. Thanks.


Best wishes,


Suchith

[OSGeo-Discuss] Fw: [D4N Stakeholders] Join the GEO Indigenous Alliance and partners for a discussion on Indigenous Peoples-led Use of Earth Observations

discussion on Indigenous Peoples-led Use of Earth Observations

Dear Data 4 Now Colleagues,



Please see below from Theadora Mills of GEO:

Tomorrow at the United Nations High Level Political Forum (HLPF), the Group on 
Earth Observations (GEO) will join a forum for Indigenous Peoples and those who 
work with them to discuss opportunities and challenges for increasing 
Indigenous Peoples engagement in the co-development, co-creation and use of 
Earth observations (EO) data and tools. This is in support of the Sustainable 
Development Goals (SDGs) to develop specific requirements for EO data, enabling 
widespread impact to indigenous culture, land holdings, climate change and 
youth empowerment.

This HLPF side event is being organised by FILAC, CANEUS, GEO, NASA, 
Conservation International, Agvesto, and Saraniasat. The HLPF is the main 
United Nations platform on sustainable development and it has a central role in 
the follow-up and review of the 2030 Agenda for Sustainable Development the 
Sustainable Development Goals (SDGs) at the global level.

Recognizing and honouring indigenous culture and knowledge, as well as 
supporting indigenous stewardship of the millions of acres of land under 
indigenous management represents a potential transformative pathway to meeting 
the SDGs.

This side event includes a panel of experts, with several representatives from 
the GEO Indigienous Alliance namely Diana Mastracci, James Rattling Leaf Sr. 
and Titus Letaapo, who will discuss key challenges and opportunities for 
inclusive engagement with indigenous peoples to advance EO design and 
applications for sustainable development at the community level. They will also 
discuss the successes and lessons learned from experience co-designing and 
applying EO technologies to help advance indigenous rights.

Earth observations which include satellite, aircraft and ground monitoring 
technologies can play a key role in supporting indigenous-led land management. 
However, Indigenous Peoples currently do not have equal access or opportunities 
to these technologies, including EO data and tools. To narrow this gap, we must 
understand the unique challenges indigenous communities face to use and develop 
EO technologies and address key topics to strengthen indigenous peoples’ rights 
and help unlock EO capabilities for all.

Join the discussion on July 9, 12:00 to 13:30 EST
