Grateful to Prof. Mia Bennett (@cryopolitics.com ,Univ. of Washington) for stirring questions at today’s EO Lab colloquium. “Pixel Politics” probed who owns the satellites—and the narratives—behind our data. Exposure→engagement→empowerment: roadmap for critical #RemoteSensing

Most scientific figures aim to be clear.
But what if they also aimed to be compelling?

I love clean, well-structured data visuals — often, they’re exactly what’s needed.

But when data is about people — shouldn’t we also show them? #DataVisualization #SciComm @humboldteolab.bsky.social

📣In our new paper we analyzed the impact of #Landsat and #Sentinel-2 🛰️ #satellite data density and SMA endmembers on trends in #grasslands ground cover:
- for monthly composites data density is irrelevant
- correct endmember definitions are critical‼️

The image is an informational graphic with the title: "Struggeling with color choices? Make your science accessible" The text is presented in a clean, modern font, with the phrase "Helpful Resource" highlighted in a light green box, emphasizing accessibility in scientific visuals. The background is a light beige color with abstract geometric shapes in muted red and light blue scattered around. In the lower right, there is a circular diagram composed of segmented parts, some of which are hatched, connected to smaller geometric shapes, including a yellow pentagon and another pentagon with a question mark inside, suggesting inquiry or guidance. The design is minimalist and visually appealing, aimed at guiding color choices for accessible scientific graphics.

To adequately study smallholder farms, researchers need access to high-resolution satellite data. This will provide critical tools, data, and scientific underpinning for the policies necessary to meet the targets defined under the SDGs. Pictured is a hand holding some beans.

Let’s grow the EO community! #EOchat #RemoteSensing

Separating woody, herbaceous, and bare cover in semiarid Sub-Saharan rangelands isn’t easy—spectral similarity makes it tricky. 🌍🛰️

We developed a Phenological Feature Space (PFS) to solve this, using Sentinel-2 time series.

Excited to share our latest work!
doi.org/10.1016/j.rs...

A drone capture of a smallholder farming landscape. Overlaid are squares of the size of typical optical satellite missions. Openly accessible data (e.g. Landsat or Sentinel-2) is often not sufficient to capture the landscape complexity in full detail, for example when trying to delineate individual fields. Here, one Landsat pixel contains fractions of multiple fields. Commercial data come at higher spatial resolution, offering potential to discriminate indivudual landscape components.

📣PNAS piece led by @philrufin.bsky.social: commercial very-high-resolution EO data is needed for monitoring SDG 2 indicators in smallholder landscapes but costs are prohibitive. A call for open access for sustainability-centered research: doi.org/10.1073/pnas... @humboldtuni.bsky.social
