Abstract: A device is provided to extract scan lines data from images of a route, said scan line data comprising only a portion of the an image that extends along a scan line, and to store this data in memory together with respective positional data pertaining to the position of the device traveling along the route in a navigable network. This scan line and positional data can be obtained from a plurality of devices in a network and transmitted to computing apparatus, for example, for use in a production of a realistic view of a digital map.

Abstract: A data storage system comprises a data storage device (2) that comprises a first file system (4) of a first type and a second file system (70, 72, 74, 76, 78) of a second, different type, and a file system control means (92) for controlling file system operations, wherein the file system control means (92) is configured to receive requests to write files to the first or second file systems, and to write to the second file system (70, 72, 74, 76, 78) in response to substantially all requests to write files that have at least one predetermined file name property to the first or second file system.

Abstract: A data storage system includes a data storage device with a first file system of a first type. At least one file stored in the first file system comprises a second file system of a second, different type. The data storage system is configured to write data to the second file system in a power-safe manner.
