Radiant Earth Foundation and RCMRD to Develop Joint Capacity Building Program focused on Machine Learning for Earth Observation in Africa

Radiant Earth and the Regional Centre for Mapping of Resources for Development (RCMRD) partnership aims to strengthen local geospatial and machine learning expertise for addressing global challenges in Africa.

Radiant Earth Foundation today announced a new partnership with the Regional Centre for Mapping of Resources for Development (RCMRD). This partnership will establish capacity building opportunities in geospatial analysis and machine learning (ML) for entities within RCMRD’s twenty Member States in Eastern and Southern Africa.

STAC Updates: Fall 2021

It’s been almost 3 months since my last blog post on SpatioTemporal Asset Catalogs (STAC), which is one of the longest stretches I’ve gone in the past few years. There’s been lots of progress and growing momentum in the community, so it seemed like a good time to pull together all the happenings in one blog post.

STAC Funding Initiatives – The first topic to share is the state of funding for the STAC ecosystem. In the previous post, I shared about our open requests for proposals. I’m pleased to announce that we’ve selected Element84 to make the new STAC website and Jonathan Healy for the STAC validation enhancements. We’ve also decided that Radiant Earth will lead the open RFP’s for the tutorial work, which will take up most of the final funding from the STAC 1.0.0 Funding effort. Once we finish up all the contracts for that initiative I’ll do a final summary blog post.

Discoverable and Reusable ML Workflows for Earth Observation (Part Two)

Describing ML Models with the Geospatial Machine Learning Model Catalog (GMLMC).
During the height of the COVID-19 pandemic, the government of Togo launched a program to “boost national food production in response to the COVID-19 crisis by distributing aid to farmers”1. To accomplish this, the government needed accurate information about the distribution of smallholder farmers throughout the country. This kind of cropland map did not exist for the country, so they worked with NASA Harvest to rapidly develop a cropland map using AI. Finding enough high-resolution labeled training data to train the machine learning model was also a significant challenge, so the team combined global and local crowdsourced labels collected using the Geo-Wiki platform2 with hand-labeled imagery in targeted areas to train a new model for predicting crop areas.

Radiant MLHub Spotlight Q&A: Gedeon Muhawenayo

Building machine learning models with open training data for precision agriculture and flood detection in Rwanda.
Our Community Voice for this quarter is Gedeon Muhawenayo, a machine learning research engineer at the Rwanda Space Agency working on machine learning for satellite and aerial image processing.Gedeon is an avid user of the open machine learning training datasets available on Radiant MLHub. In this Q&A, Gedeon talks to us about building machine learning models for precision agriculture and flood detection in Rwanda.

2021 Machine Learning for Earth Observation Market Map Release

Now featuring 250+ organizations that focus on machine learning applications with satellite data

The latest interactive Machine Learning for Earth Observation Market Map, a curated list of organizations focused on different machine learning aspects with a satellite data pipeline, is available for download. This release includes an additional list of 100+ organizations, thanks to a crowdsourcing effort on social media. Earlier in September, we asked our followers on Twitter and LinkedIn to identify organizations that we missed in the earlier version of the market map or were established since then. The large number of contributions from people in such a short period speaks of the niche area of machine learning (ML) for Earth observation (EO). The entries hint toward the incredible aptitude of organizations to optimize these innovative technologies and expand them in the service of humanity.

STAC 1.0.0: What’s next for the STAC Ecosystem?

Following up on our SpatioTemporal Asset Catalog 1.0.0 announcement, this post will finish our mini–series diving into the STAC specification and the ecosystem around it. This one is really about the future, where we see STAC heading in the next six months and beyond. And after this I hope to start an in-depth series of STAC posts that dives deeper into individual projects, highlighting all the great software and data in the STAC ecosystem.
The ‘STAC Ecosystem 1.0’ Vision
One of the core tenents of the STAC Community is that we focus on the process of building an interoperable ecosystem, with the specification serving as a record of the current state of collaboration. With the release of 1.0.0, it is our hope that the core of that collaboration now has an incredibly solid foundation. But there is much, much more to do in order to realize the vision of STAC: we won’t be ‘done’ until every single ‘geospatial asset’ has an associated STAC record.

Radiant MLHub Spotlight Q&A: Macroecology and Society Lab

Building application-ready tools and data for policymakers, resource managers, and other scientists to understand global dynamics in human-environment systems.
Our Community Voices for this quarter are Dr. Carsten Meyer, Mr. Ruben Remelgado, Dr. Steffen Ehrmann, and Ms. Caterina Barrasso from the German Centre for Integrative Biodiversity Research (iDiv) Macroecology and Society Lab. They are working on several projects to detect and understand global dynamics in human-environment systems, focusing on human land use, its underlying societal drivers, and its ecological consequences. The research team uses numerous datasets from Radiant MLHub to model crop suitability layers, which will inform the systematic downscaling of crop statistics into pixel-scale crop type classifications.

Discoverable and Reusable ML Workflows for Earth Observation (Part 1)

Using STAC to catalog machine learning training data.
Researchers and data scientists are increasingly combining Earth observation (EO) with ground truth data from a variety of sources to build faster, more accurate machine learning (ML) models to gain valuable insights in domains ranging from agriculture to autonomous navigation to ecosystem health monitoring. These models are integrated into analytic pipelines that generate on-the-fly predictions at scale. The accuracy of these inferences are then evaluated using well-defined validation metrics and the results used to improve the performance of the original model in a continuous feedback loop.

If this sounds like a complex process, that’s because it is! Ad-hoc techniques for handling these workflows may work well within a single organization, but can lead to a bewildering array of algorithms and data for end-users.

STAC API Version 1.0.0-beta.2 released!

The SpatioTemporal Asset Catalog (STAC) Community is pleased to announce the release of version 1.0.0-beta.2 of the STAC API specification! A big thanks to Phil Varner for leading this release, and to everyone else who pitched in.

What is STAC API? As we are welcoming many new people to the STAC community with the core STAC 1.0.0 release it’s probably worth explaining what this ‘API’ release is all about. STAC originally started from a desire to make a common API to help interoperability between satellite data providers, but soon evolved to focusing on the core JSON language to enable more general geospatial interoperability. The STAC repository initially contained both the API specification along with the three ‘core’ specs (Item, Catalog & Collection). But it was clear that the API really depends on the core, and expands it with additional functionality, so after version 0.9.0 we decided to split STAC into two repositories.
