Principal components from 1992-2024 night-light images for India

There are two global Lights at night images data sets (as far as I am aware of): the #VIIRS-based (500 m) covering 2011-2024 (doi.org/10.3390/rs13...) and DMSP (1 km) but covering 1992-2024 (doi.org/10.1038/s415...). I've used both data sets to derive Principal Components: doi.org/10.5281/zeno...

OpenLandMap-soildb: global soil information at 30 m spatial resolution for 2000–2022+ based on spatiotemporal Machine Learning and harmonized legacy soil samples and observations Abstract. There is increasing interest in global dynamic soil information with changes in soil properties mapped over time and at high spatial resolution. Thanks to long-term, multi-temporal, and fine...

The v1 of the 30 m resolution global soil carbon density, SOC content, pH, texture fractions, bulk density and soil types (USDA subgroups) now out; soil carbon and soil pH are mapped as dynamic soil variables for 5yr intervals. Preprint: doi.org/10.5194/essd...
Data: github.com/openlandmap/...

📢 Researchers wanted!
- PhD candidate: Hybrid geospatial modeling of carbon fluxes and associated uncertainty for scenario testing (opengeohub.org/jobs/researc... with Uni of Utrecht),
- Research assistant: modeling land use & land cover dynamics using ML & AI (opengeohub.org/jobs/researc...),

Embeddings simultaneously solve 3 fund problems of EO data science:
- data usability increases complete consistent and harmonized components (ARD),
- data is compressed as you can combine many overlapping systems,
- ML would likely lead to higher accuracy as it is easier to reduce model complexity,

Say goodbye to human-readable EO images. Computers do not need to look and think as humans to get work done. Accuracy and efficiency is all you need. Google EE team now makes 10m ARD (annual starting from 2020) synthetic bands / deep features (64 in total): developers.google.com/earth-engine...

Interesting to see these numbers at #LPS25: @esa.int costs about €8B per year; Copernicus (especially Sentinel-1 a -2) is now the world leading source of open EO data, but this is still *only* 0.06% of GDP. USA invests almost 3 times more (per capita).
