Earlier this March I had the honor to receive the Best Poster Award for the event that took place at the end of November 2022, JPL Postdoc Research Day. There were 5 categories and I was awarded for the Earth Science: Water, Land, Biome, and Carbon Cycle category. I presented my work titled “Amazon forest structure from space”. Photos by …
New publication is now open-access in the International Journal of Applied Earth Observation and Geoinformation! We propose a methodology based on dynamic time warping and random forest to automatically generate crop type samples needed for supervised classification. Check out the paper at the link below! Belgiu, M., Bijker, W., Csillik, O., Stein, A., 2021, Phenology-based sample generation for supervised crop …
New publication is now open-access in PLoS ONE: Near-real time aboveground carbon emissions in Peru This study used Planet Dove quarterly and monthly mosaics in combination with airborne LiDAR measurements of canopy height in order to estimate the aboveground carbon stocks over multiple time periods and then used the IPCC stock-difference method to obtain the carbon emissions at yearly, quarterly, …
New article that tackles the challenges of estimating canopy height from spectral and textural information from Planet Dove images is now published in Remote Sensing (click to access): Csillik, O.; Kumar, P.; Asner, G.P. Challenges in Estimating Tropical Forest Canopy Height from Planet Dove Imagery. Remote Sens. 2020, 12, 1160. This work can be a helpful advancement towards better monitoring of tropical forests, …
The article published on January 14, 2020, in Environmental Research Letters, presents an approach for monitoring the aboveground carbon emissions in Madre de Dios, Peru, in an area highly affected by the gold mining activities, most often illegal and small-scale. We used Planet imagery, Sentinel-1 radar images, topography and airbone Lidar within a neural network framework to estimate how much …
You can access the publication on Nature’s Scientific Reports webpage. Csillik, O., Kumar, P., Mascaro, J., O’Shea, T. and Asner, G.P., 2019. Monitoring tropical forest carbon stocks and emissions using Planet satellite data. Scientific Reports, 9(1), 17831. We have developed a method to monitor carbon emissions from tropical forests at an unprecedented level of detail. The approach will provide the basis for …
A new paper is now published in Remote Sensing journal (open-access). It uses Sentinel-2 time series of vegetation indices to extract temporal pattern for crops in highly managed agricultural areas in Texas and California. It uses the dynamic time warping algorithm to match the highly heterogeneous patterns of crops and test multiple time constrained on DTW. We applied the analysis …
On January 8th, 2019, I had the honor to be awarded Romania’s Best Student in Europe, graduate level, during an event organized by the League of Romanian Students Abroad. The LRSA is one of the biggest Romanian NGO outside its borders and organizes every year an event where the achievements from the previous academic year are highlighted. Considering the size …
On January 16th, 2019, I was a presenter for an eCognition webinar focused on Deep Learning, UAVs and Precision Agriculture. The presentation was focused on the methods and results from the paper published few months earlier in Drones. It was my first experience as an online presenter to a larger audience (300+ participants) and I hope I made my point …
My current and first postdoctoral project I am working on, together with a great team, is now featured in Medium and Planet Pulse. We are using very high resolution Planet images in combination with airborne LiDAR data over large areas of Peru to estimate forest structural characteristics and aboveground carbon stocks. Taking advantage of high spatial and temporal resolutions of …
