Although the analysis of globular cluster systems (GCSs) in nearby spirals provides relevant information about their evolutionary history, it is challenging because of their angular extension. In this work we takeadvantage of the large field-of-view of the Javalambre Photometric Local Universe Survey (J-PLUS) to perform a wide-field study of the GCS of the spiral M 81. Its extension and population are estimated, and its colourdistribution is analysed.
