Generating a global training dataset while supporting social initiatives and sustainable practices.

Labeling satellite imagery is the process of applying tags to scenes to provide context or confirm information. These labeled training datasets form the basis for machine learning (ML) algorithms. The labeling undertaking (in many cases) requires humans to meticulously and manually assign captions to the data, allowing the model to learn patterns and estimate them for other observations.

For a wide range of Earth observation applications, training data labels can be generated by annotating satellite imagery. Images can be classified to identify the entire image as a class (e.g., water body) or for specific objects within the satellite image. However, annotation tasks can only identify features observable in the imagery. For example, with Sentinel-2 imagery at the 10-meter spatial resolution, one cannot detect the more detailed features of interest, such as crop types but would be able to distinguish large croplands from other land cover classes.

Using the Python client to discover and download training datasets without managing API requests.

We are excited to announce the first beta release of the radiant_mlhub library, a Python client for working with the Radiant MLHub API! With this release, users can work with Radiant MLHub datasets through an intuitive Python interface without having to worry about constructing API requests and managing authentication.

The library is still in the early stages of development, but we encourage you to try it out and give us feedback on how well it addresses your use-cases. This article will walk you through the process of installing and configuring the library, navigating datasets and their collections, and downloading training datasets. For more detailed documentation of the Python library, please see the official documentation here. A basic knowledge of Python programming is recommended.

A little over a year ago, we launched the first iteration of Radiant MLHub in the form of a STAC-compliant API, which allows you to browse our training data collections and list and download individual assets from the items within those collections. Today, we’re announcing the ability to download an archived version of training datasets with just a single-click download. In this post, we’ll describe the process for downloading datasets, the structure of the archived datasets, and provide some tips for effectively traversing the downloaded datasets.

We are now offering three different methods of downloading our datasets. The easiest method, downloading on our registry, can be accessed by navigating to a dataset page and clicking on the “Download” link for each collection you would like to download. Clicking this link will direct you to our dashboard, which will ask you to login if you are not already authenticated and then begin the download process for that collection.

Meet the 150+ organizations that focus on machine learning applications with satellite data. 

The updated Machine Learning for Earth Observation Market Map is finally here!

The ML4EO market map is a curated list of organizations focused on different machine learning aspects with a satellite data pipeline. This release includes an additional list of 50 organizations, which we missed in the first version published in September 2020.
