In this article we’ll obtain seasonal data from the Sentinel 2 constellation. I will plot the mean NDVI for two types of agriculture in a timespan of three years and clean the data by removing anomalies. You can follow along with the project using the notebook on GitHub. Method After using…

Tips, tricks and warnings when creating a building detection machine learning model using open-source reference data. — Written by Sara Verbič. Work performed by Sara Verbič, Devis Peressutti, Nejc Vesel, Matej Batič, Žiga Lukšič, Jan Geršak, Matic Lubej and Nika Oman Kadunc. We wanted to create a large training dataset for automated building detection in Africa, so we reviewed open-source datasets for that purpose. Machine-generated datasets lack…

A simple implementation of angular normalisation for Sentinel-2 reflectance. — Bidirectional reflectance distribution function or BRDF… you may not have heard of this term before, but you have already experienced it in your everyday life without knowing it. Have you walked along the seashore and observed the sparkling sunlight bouncing off the rippled surface of the water? Or maybe you…

In this article I am going to explore how to use satellite imagery to map the NDVI index of a region between Belgium and the Netherlands. I will use contours and use masking to obtain a high-contrast map of the land areas. Method Extract 13 bands from Sentinel L2 Calculate NDVI …

Written by Grega Milcinski and Megha Devaraju The Copernicus Data Space Ecosystem, introduced in our previous blog post, will act as the main distribution platform for data from the EU Copernicus missions (service will be fully operational in July 2023). …

A new service to better exploit the EU’s Copernicus satellites data Copernicus is the Earth Observation component of the European Union Space Programme, co-funded with the European Space Agency (ESA). ESA, to whom the Copernicus Data Access initiative has been delegated by the European Commission, has selected an industrial team…

Featuring scripts and written stories using open EO data — Authors: Monja Šebela, Sabina Dolenc While we are on a mission to find new and innovative ideas and scripts, organizing Sentinel Hub Custom Script contests is one of our things. Together with our partners, the Euro Data Cube, Copernicus EU Earth Observation program, and the European Space Agency (ESA), we’ve…

Operational Sentinel-3 Snow and Ice Products Within EDC — Areas with permanent snow and ice cover, namely those in the Arctic, play a crucial role in maintaining a global energy balance by reflecting as much as 90 % of the radiation from the sun back into space. Doing so, the Earth absorbs less heat, keeping it cooler. As snow…

Normalized Difference Yellowness Index (NDYI) — A guest blog post by Mario Alberto Guzmán Soza Foreword by Sentinel Hub This post is part of a series of guest blog posts written by authors talking about their entries to the Sentinel Hub Custom Script Contest. The author is one of the winners of our special edition of the Contest — Climate…
