Publication: Gold mining impacts in the Peruvian Amazon

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 …

Publication: Monitoring tropical forest carbon emissions with Planet data

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.

Publication: Object-based dynamic time warping for crop mapping

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 …

Publication: Using deep learning to detect citrus trees

A new publication is now open access in Drones, a new MDPI journal. This is the first open peer-review publication for this journal, meaning that you can access the review reports and the responses to reviewers. This paper is a result of a great collaboration that was a result of my research stay at UC Berkeley in 2017, where this …
