Methods of generating heat maps of assets using clustering of assets are disclosed. Some methods include receiving a list of assets, assigning the assets to one or more heat range categories based on the status of the assets, assigning assets operating within a zone to a zone cluster, assigning the assets of the zone cluster to category clusters based on the heat range categories assigned to the assets.
