Method for representing a computer-generated simulation environment simulating a real environment, having a database containing the data of the real terrain and the real objects situated in the terrain, and wherein the data - are acquired by way of an evaluation of image recordings recorded during an overflight over and/or a drive through the real environment, - comprise a geospecific image representation of the real terrain and/or of the real objects, and - are stored, inter alia, as raster data in the database in a primary memory, wherein a part of the database is transmitted to a representation memory for representing part of the simulation environment on the basis of a freely selectable representation position and representation direction of the representation of the simulation environment, characterized in that memory regions of a specific size (A, B, C) are predefined in the representation memory and the data of the database that are to be transmitted to the representation memory are adapted in at least one property to the size (A, B, C) of the predefined memory regions before the transmission, wherein environment memory regions are defined in the memory regions, which environment memory regions serve in each case for imaging a tile of the simulation environment with a fixed base area, wherein the entirety of the environment memory regions forms a contiguous partial area of the simulation environment in the environment of the freely selectable representation position, wherein the environment memory regions are assigned once or dynamically to the respective tiles of the simulation environment with reference to the freely selectable representation direction, and wherein tiles of the simulation environment in the vicinity of the representation direction are assigned larger environment memory regions than tiles of the simulation environment that are located further away from the representation direction. - are acquired by way of an evaluation of image recordings recorded during an overflight over and/or a drive through the real environment, - comprise a geospecific image representation of the real terrain and/or of the real objects, and - are stored, inter alia, as raster data in the database in a primary memory, wherein a part of the database is transmitted to a representation memory for representing part of the simulation environment on the basis of a freely selectable representation position and representation direction of the representation of the simulation environment, characterized in that memory regions of a specific size (A, B, C) are predefined in the representation memory and the data of the database that are to be transmitted to the representation memory are adapted in at least one property to the size (A, B, C) of the predefined memory regions before the transmission, wherein environment memory regions are defined in the memory regions, which environment memory regions serve in each case for imaging a tile of the simulation environment with a fixed base area, wherein the entirety of the environment memory regions forms a contiguous partial area of the simulation environment in the environment of the freely selectable representation position, wherein the environment memory regions are assigned once or dynamically to the respective tiles of the simulation environment with reference to the freely selectable representation direction, and wherein tiles of the simulation environment in the vicinity of the representation direction are assigned larger environment memory regions than tiles of the simulation environment that are located further away from the representation direction.
