    摘要： A method and system for requesting information from a server are provided. The method may include sending, by a client to a server, an HTTP GET request to retrieve at least a portion of at least one derived data file, the at least one derived data file being dynamically generated by the server in response to the request using a data file virtualization policy and at least a portion of a data file. The data file virtualization policy and the data file may be stored in a storage accessible by the server, and the dynamic generation may comprise an aligned unbuffered direct read operation from the stored data file of a data size that is aligned to an integer multiple of the storage's block size. The at least the portion of the at least one derived data file may then be received by the client from the server.

    摘要： A method and system for storing data files are provided. The method includes receiving from a client computer system in communication with a server computer system, a first data file and a first data file virtualization policy; storing the first data file and the first data file virtualization policy on a storage device in communication with the server computer system; and deriving one or more second virtual data files using information from the first data file and the first data file virtualization policy, the one or more second virtual data files not being stored on the storage device. The method further includes generating a directory listing of the one or more second virtual data files such that the one or more second virtual data files appear to the client computer system as if the one or more second virtual data files is stored in the storage device.

    摘要： A computer system for processing a viewport within an image arranged as a matrix of tiles from a container file is disclosed herein. The computer system includes one or more processors configured to: (a) receive a request to read data of the viewport starting from a point of origin of the viewport, the viewport having a pixel width and a pixel height, the viewport being a portion of an image that is stored in a record within the file container; (b) compute column numbers or row numbers, or both, of the tiles containing the viewport; and (c) read in parallel or asynchronously each row or each column of tiles containing the viewport.

    摘要： A method of making a video stream from a plurality of viewports within large format imagery is described. In one embodiment, the method includes retrieving a plurality of viewports within a plurality of images, each image being arranged as a matrix of tiles, from a file container. The method includes inputting parameters including an identification of a plurality of records where the plurality of images containing the plurality of viewports are stored, an origin of each of the plurality of viewports and a pixel width and a pixel height of each of the plurality viewports. The method further includes requesting the plurality of viewports from the file container using the parameters; and reading data of each of the plurality of viewports starting from the origin of each or the plurality of viewports. The method may further include arranging the plurality of viewports as a video codestream of a group of pictures.
