Nomination for WWF's "Environmental Hero" award

In mid-September I got an email that said “ditt arbete med Birding Therapy som en av de nominerade av Årets Miljöhjälte i kategorin biologisk mångfald” (your work with Birding Therapy is one of the nominees for this year’s Environmental Hero award in the biodiversity category"). At first I didn’t know what to think and thought it was a phishing/malware type of spam. But then it sunk in that this is real, and it’s difficult to put into words how I felt. I didn’t think that anyone was paying attention to the small side project I started to get more people, particularly underrepresented groups, out into nature and birding.

TEDx talk on “Satellites for Everyone”

My TEDx talk is now available on YouTube. The basic premise of the talk is that when you put all the recent advances in perspective, it results in a democratization of data on one hand, and science on the other. It means that anyone with a computer and a decent internet connection can have access to satellite data, process them using open source methods and extract information for their own use. This not only helps accelerate the rate at which scientific discoveries are made but also makes knowledge sharing and international development more equitable and inclusive.

Macroscopes on Earth – Why we live in the golden age of satellites

As most of us know, our planet is changing on several fronts such as climate change, polluted oceans, biodiversity declines, land degradation, and so on. But Earth is a big place and keeping tabs on these changes is huge task. There is currently one tool at our disposal that can provide us with the big picture about the health of our planet. That tool is the system of satellites that observes Earth day and night.

New milestone: My paper is now the most read and cited

, ,

This is an exciting milestone for me. As of December 13th, my open access study on the Land cover and land use classification performance of machine learning algorithms in a boreal landscape using Sentinel-2 data that was published in 2020 is the most read (22,885) and most cited (101) paper in the journal GIScience & Remote Sensing.

Tutorial: Machine learning classification of Sentinel-2 satellite imagery using R [Updated]

,

Note: This tutorial was updated on April 20th, 2020 based on reader feedback.

In this short post, I would like to help you conduct your own machine learning classification of Sentinel-2 data using the open source package R. The process is pretty straightforward if you have experience in remote sensing and image classification. Even if you don’t have extensive experience, basic knowledge of remote sensing terminology is sufficient.

Test pixelwise correlation between two time series of gridded satellite data in R

Satellite time series data are useful for studying biophysical how variables change over time and understanding what causes those changes. Recently, I was looking into correlating two time series datasets over Africa to look at the relationship between net primary production (NPP) and rainfall. After a futile attempt to find an “out-of-the-box” software package that does this, I created an R function to speed things up.

Behind the Paper: Comparing machine learning algorithms using Sentinel-2 data

,

The field of machine learning is moving fast, and it seems that new fancy algorithms coming out every week. Sometimes, it is confusing to figure out which algorithms are best suited for which purpose. This is particularly the case when it comes to land-use and land-cover classification using multidimensional satellite imagery because most of the new algorithms are tested with either binary or uni-dimensional data.
