摘要： This invention relates to a graphic data processing system, and is more particularly directed to provide an easy-to-operate system and displaying method thereof, for generating scene data from map data and retrieving and displaying attributes containing guide information of ground objects in a scene. In the first place, when a visual point is directed from above to below, a planar map is displayed, and as the visual point shifts in a horizontal direction, a three-dimensional scene image is generated and displayed from a map. Secondly, a three-dimensional window is displayed in a display, and graphic data is displayed inside the window.

摘要： A figure data display method and system in which the contents to be stored and constituting data are stored in the form of figure data divided into a plurality of partial areas, a file information table is prepared which registers therein figure area information, along with volume information of the figure data, in the sequence of serial numbers allocated to the partial areas dependent on their positions, and those partial areas, which are necessary for display of the figure data, are searched within a range of the registered serial numbers. By preparing the figure data represented in the compressed form by taking relative values between the coordinate values of respective features points in the figure data, or by retrieving file names in a manner involving direct searching the figure data from a storage medium, operation from the step of reading the figure data to the step of displaying the same can be speeded up. High-speed infinite scrolling can also be achieved by setting an adjacent area based on the above retrieval when the predetermined area to be displayed is exceeded upon scrolling of the display area, and then deleting the unnecessary area.

摘要： A data communication apparatus comprises: means for dividing data to be transmitted into a plurality of blocks and extracting the data from each block; a first multi-layered neural network of three or more layers which has weighting coefficients to output the same data as the input data for the data extracted from each block and which can output data from an intermediate layer; the transmission data extracted from each block being inputted to the first neural network and outputted from the intermediate layer; means for encoding the transmission data which is outputted from the intermediate layer of the first neural network and, thereafter, transmitting; means for receiving and decoding the transmitted data; a second multi-layered neural network of three or more layers which has the same weight coefficients as those of the first neural network and can input data from an intermediate layer; the decoded data of each block being inputted to the second neural network and outputted from an output layer; and means for restoring the data on the basis of the output data from the output layer of the second neural network.
