In this article, you will learn how to classify a landscape raster via k-means clustering

1. Add the raster layer 188_pca_indices.tif into a QGIS project. It should be available in the course data.
2. Open the k-means classification algorithm provided by the Orfeo toolbox. It can be found in the processing toolbar under Toolbox --> Orfeo Toolbox --> Learning --> Unsupervised KMeans image classification.
