Abstract: A method is disclosed herein which comprises receiving a user request for map information at a server. The method also comprises requesting one or more base map tiles from a remote server based on the user request, the request including zoom level information and tile position information. At the server, the request is normalised based on the zoom information and the tile position information. The method then comprises defining a map view area based on the normalised request, obtaining vessel data relating to a plurality of vessels, determining for each of the plurality of vessels if the vessel lies within the map view area, and creating a new map tile comprising the vessel data for the vessels determined to lie within the map view area. The method then comprises causing display of the user requested base map tiles and overlaying the new map tile at a user device.

Abstract: An apparatus is provided for positioning a plurality of cassettes within an automated printing plate handler. In a plate handler, a plurality of cassettes each contain a supply of printing plates for delivery to an automatic plate-recording device. The apparatus includes a separate support table for supporting each of the plurality of cassettes within the plate handler and an elevator device for moving each of the support tables along a vertical axis of the automated plate handler. The automated plate handler is configured to automatically position a selected cassette in a first position to facilitate removal of the cassette from the handler. The plate handler further includes a platform, which substantially forms an extension of the support table supporting the selected cassette in the first position. The platform provides a second position, at which the selected cassette is to be one of, loaded or unloaded.
