Exploring Coral Reefs in the Maldives from Space! 🛰️🐠

Using free satellite data from Sentinel-2 and the powerful tool Google Earth Engine, I mapped potential coral reef zones in the Maldives — one of the most stunning and fragile marine ecosystems in the world.

💡 By applying the NDWI (Normalized Difference Water Index), I was able to highlight shallow water areas — often where coral reefs thrive — and visualize them in bright yellow over high-resolution satellite imagery.

If you're interested in the code or want to try it yourself, feel free to comment or message me — I'm happy to share! Let's use tech to protect our oceans 💙🌊

Myanmar Earthquake: A Devastating Impact

A powerful earthquake recently struck Myanmar, causing widespread damage and affecting many communities. The images below show the extent of destruction, highlighting the urgent need for support and disaster response efforts.

Remote sensing plays a crucial role in assessing damage, guiding relief operations, and helping build resilience for the future. By using satellite data, we can better understand the impact and support recovery efforts.

Let’s stand together in solidarity with the affected communities.
On March 28th, 2025, a 7.7-magnitude earthquake struck the Sagaing Region of Myanmar. Synspective StriX Satellite captured the Collapsed Ava Bridge in Mandalay.

This earthquake caused significant damage to buildings and infrastructure within Myanmar and neighboring countries. Our heartfelt sympathies go out to all those affected by this disaster.

# Vietnam actively developing its carbon market as part of its commitment to achieving net-zero greenhouse gas (GHG) emissions by 2050. Remote sensing technology plays a pivotal role in supporting the carbon market by enabling robust monitoring, reporting, and verification (MRV) of carbon stocks and emissions, particularly in forestry, agriculture, and coastal ecosystems. This study explores the integration of multi-source satellite data, including SPOT 6, Pléiades-1A, Pléiades-1B, Landsat, Sentinel, and other Earth observation platforms, to enhance carbon accounting and management practices in Vietnam.

High-resolution imagery from SPOT 6, Pléiades-1A, and Pléiades-1B is utilized for detailed forest cover assessments, biomass estimation, and precise monitoring of land use changes, contributing significantly to the Reducing Emissions from Deforestation and Forest Degradation (REDD+) initiatives. Landsat data, with its extensive historical archive, supports long-term land use and land cover (LULC) mapping, enabling the detection of deforestation trends and the assessment of carbon fluxes over time. Meanwhile, Sentinel-1 and Sentinel-2 provide complementary radar and optical data for dynamic monitoring of agricultural emissions and coastal carbon stocks, particularly in mangrove forests and other blue carbon ecosystems. The integration of these datasets enhances the spatial and temporal accuracy of carbon stock assessments and helps establish transparent MRV systems that align with international standards.

The study also highlights challenges such as data accessibility, technical capacity, and the need for standardized verification methodologies. Additionally, opportunities to apply advanced technologies, including digital twins, artificial intelligence (AI), and machine learning (ML), in remote sensing are discussed. These technologies can optimize carbon accounting, support Vietnam’s engageme
