Where Does This Amazing Data Come From?

So, where does this treasure trove of information come from? The Esri 2020 Global Land Cover data is primarily derived from the Sentinel-2 satellite imagery. Sentinel-2 is part of the European Union's Copernicus program, and it provides high-resolution, multispectral imagery of Earth's surface. These satellites are equipped with advanced sensors that capture information about the Earth's surface in various wavelengths of light. The data collected from the Sentinel-2 satellites is then processed using sophisticated algorithms and machine learning techniques to classify the land cover types. This process involves training the algorithms to recognize different land cover features based on their spectral signatures and other characteristics. Esri uses its expertise in GIS and remote sensing to process, validate, and refine the data, ensuring its accuracy and usability. The processing pipeline involves several steps, including atmospheric correction, geometric correction, and classification. Atmospheric correction removes the effects of the atmosphere on the imagery, while geometric correction ensures that the imagery is accurately geolocated. The classification step is where the machine learning algorithms are applied to identify and categorize the different land cover types.

But the magic doesn't stop there. Esri also incorporates other data sources and techniques to improve the accuracy and completeness of the data. This includes using other satellite imagery, such as Landsat, and incorporating ancillary data like digital elevation models and existing land cover maps. This multi-source approach helps to fill in gaps in the data and improve the overall quality of the land cover map. In the end, the Esri 2020 Global Land Cover data is a testament to the power of collaboration and innovation in the field of geospatial science. The Sentinel-2 satellites act like the eyes in the sky, collecting the raw data, and Esri's expertise transforms it into a valuable resource that is useful for researchers, policymakers, and anyone interested in understanding our planet. The continuous updates and refinements to the dataset further ensure its relevance and accuracy. The use of cloud computing platforms allows for efficient data processing, making the data accessible to users worldwide.
