Cover Story: The performance of a machine learning algorithm depends on the underlying data representation. Geospatial data come in many different shapes and forms, including points of interest, boundaries, trajectories, images and many more. To maximise the performance of the machine learning algorithms operating on such data, they should be converted into a representation that encodes the semantics by mapping similar entities to similar representations. Self-supervised representation learning (SSRL) performs this task automatically without the need for expensive data annotation. This article reviews the existing research literature on SSRL in the field of geographical information science and discusses different types of representations learnt, SSRL models used, downstream applications, and performance improvements.
