Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reading data from a storage medium for satellite observation data, and more particularly to a distribution data input method and apparatus for inputting data from a distributed storage medium for satellite observation data to a computer.

[0002]

2. Description of the Related Art FIG. 3 is a diagram showing a configuration of a conventional example of a distribution data input device for satellites and the like.

Conventionally, as a method of inputting distribution data such as satellites, only the image portion is read out from the recording medium by the operator inputting the number of files, the record length, and the number of records. Is a storage medium distributed from computer-compatible tape (CCT) 1 which is a storage medium distributed by creating a unique input program 11 for each data according to the format description provided by the Japan Space Agency (B procedure). The data was read by inputting (procedure A) and outputting to the data file 10.

[0004]

In the above-mentioned conventional general-purpose input method of distributed data for satellites and the like, data other than images cannot be input unless special work and software are created by an operator and a programmer. Therefore, knowledge of the data format and knowledge of software are required to input the distribution data such as satellites. When using various data, enter the program according to the format of the data while creating the program according to the format manual. There was a problem that I had to do.

Also, in the development of processing equipment and analysis equipment for inputting distributed data such as satellites, it has been an object to realize efficient development of input software which has been individually created in the past.

It is an object of the present invention to provide an efficient and highly flexible distribution data input method and device for satellites, etc. by converting the data format into a database.

[0007]

The satellite distribution data input method of the present invention is a method for inputting images and images in a satellite distribution data input method for inputting satellite observation data distributed by the Japan Space Agency from a storage medium to a computer. A step of classifying various formats for inputting data other than the data and registering in a database, a step of reading and storing header information from a data storage medium storing distribution data such as satellites, and using the header as a key , A step of selecting a data format to be used from the database and reading it, and a step of inputting distribution data such as satellites to a computer according to the read data format.

Further, when the header has a special format, the present invention also includes a case where the format is selected manually by the operator.

The satellite distribution data input device of the present invention is a satellite distribution data input device for inputting satellite observation data distributed by the Space Development Agency from a storage medium to a computer. Means for classifying various formats for inputting data into headers and registering in a database; means for reading and storing header information from a data storage medium storing distribution data such as satellites; It has means for selecting and reading the data format to be used from the database, and means for inputting distribution data such as satellites to the computer according to the read data format.

Further, in the case where the header has a special format, the present invention also includes one having a means for selecting the format by manual input by an operator.

[0011]

[Function] In order to access images and data other than image data from the storage medium of observation data distributed by the Japan Space Agency, various input formats created arbitrarily according to the format manual are aggregated and database In order to access the necessary data using the header of each data storage medium such as satellite distributed data as a key, the format can be saved from the database without creating an access format at each workstation or operator intervention. You can search, which makes it accessible through your computer.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a flow chart of an embodiment of a general-purpose input data for satellite distribution data according to the present invention, and FIG. 2 is a block diagram of an embodiment of a distribution data input device for satellite etc. for executing the flow chart shown in FIG. .

This general-purpose input device for distributed data such as satellites is constructed by one workstation, several kinds of input devices, and a network. That is, a format is created for reading data from a storage medium according to a format manual and stored in a computer compatible tape (CCT) 1, flexible disk (FD) 2, magneto-optical disk (MO) 3, other electronic mail 4, etc. General-purpose database 5 in which various formats are registered, input / output devices (not shown) for various storage media, header information read from distributed various storage media CCT6, MO7, digital audio tape (DAT) 8, etc. It has general-purpose software 9 for reading data from a corresponding storage medium via a computer in a format automatically searched from the database 5.

Next, the operation of the present distribution data general-purpose input device for satellites will be described with reference to the flowchart of FIG.

The data format stored in each storage medium is copied and input into the work area of the fixed disk of the workstation (step 21). Step 21
The data format copied in step 5 is registered in the database 5 for each header (step 22). Header information is read from a medium in which distribution data such as satellites is stored, for example, CCT6 (step 23). The data format to be used is selected from the database 5 according to the read header information (step 24). In this case, if the header has a special format, it may be selected by the operator (step 25). Load the selected data format into the workstation (step 2
6). After that, the workstation writes the data from the storage medium CCT6 to the data area of the fixed disk of the workstation by the software 9 (step 2).
7) Further, copy to the data file 10.

As described above, the present invention enables efficient input of satellite distribution data instead of the conventional input procedure.

For example, if the data format is registered once, the work can be started from the reading of the header information of the distribution data of satellites and the like thereafter. Also, in the case of a newly created data format, by registering it in the database, it is possible to use it thereafter to input distribution data such as satellites.

The above-described embodiment is an example of a preferred embodiment of the present invention, and the present invention is not limited to this, and various modified embodiments can be made without departing from the gist of the present invention. It shall be included in the invention.

[0020]

As described above, according to the present invention, the data format of the satellite distribution data input, which has been individually developed and created, is registered in the database, and when the storage medium of the corresponding satellite distribution data is input. Since it is searched and used, when trying to read out the distribution data, it is not necessary to create a data format again or rely on the operator, and anyone can easily download the data from the storage medium of the distribution data such as satellite. There is an effect that can be read.
