A marine environment display device for geo-referencing an image stream of a marine environment captured by a camera, the marine environment display device comprising: an image receiver configured to receive an image of the image stream from the camera; a location receiver configured to receive an object location of an object; an image generator configured to generate, from the image, a projected image having a virtual marine environment provided from chart data and corresponding to the camera position and field of view of the camera, wherein location information is associated with each of a plurality of points on the projected image and the image is projected onto the virtual marine environment; an object generator configured to generate an object indicator (56,58) at a position on the projected image based on the object location and the location information, wherein the object indicator (56, 58) is generated at the position on the projected image based further on each of a plurality of points on the virtual marine environment; a display configured to display the projected image and the object indicator (56,58) at the position on the projected image; a selected point receiver configured to receive via an input device a user input selecting a point of the plurality of points on the projected image; a location retriever configured to retrieve a location associated with the selected point; wherein the display is further configured to display the location of the selected point; an operation performer configured to perform a zoom operation and/or a pan operation centered on the selected point, wherein the operation performer is further adapted to display during a panning or zoom operation centered on the selected point the virtual marine environment in a portion of the display device where the projected image is not available until a current projected image is available. an image receiver configured to receive an image of the image stream from the camera; a location receiver configured to receive an object location of an object; an image generator configured to generate, from the image, a projected image having a virtual marine environment provided from chart data and corresponding to the camera position and field of view of the camera, wherein location information is associated with each of a plurality of points on the projected image and the image is projected onto the virtual marine environment; an object generator configured to generate an object indicator (56,58) at a position on the projected image based on the object location and the location information, wherein the object indicator (56, 58) is generated at the position on the projected image based further on each of a plurality of points on the virtual marine environment; a display configured to display the projected image and the object indicator (56,58) at the position on the projected image; a selected point receiver configured to receive via an input device a user input selecting a point of the plurality of points on the projected image; a location retriever configured to retrieve a location associated with the selected point; wherein the display is further configured to display the location of the selected point; an operation performer configured to perform a zoom operation and/or a pan operation centered on the selected point, wherein the operation performer is further adapted to display during a panning or zoom operation centered on the selected point the virtual marine environment in a portion of the display device where the projected image is not available until a current projected image is available.
