Compression Tool for Aeronautical Data

conference paper

English

In todays world, it is still necessary to easily access accurate information. Aeronautical information shall be made available quickly for safety reasons and must simultaneously maintain their accuracy. Todays system is introduced in paper form, the paper form is integrated and than interpreted according to the needs of different categories of users. In this paper form each time there are the risks of data loss and their consistency and integrity. This can compromise the safety and this data can not be accepted. In future applications, there are aeronautical data with a high level of integrity. The concept of AIXM is the model for the exchange of aeronautical information in digital form. Model AIXM is important for use in aviation, where the trend is to transmit information not only on paper but increasingly also in the electronic version. When transferring data in this form it is very appropriate to limit the transmitted data only on current information, since the capacity of the transmission channel is limited. Therefore, it is beneficial to use compression of AIXM. This article is focused on XML compression and describes created compression tool for AIXM. Tool uses lossy and lossless compression methods. Generally, the lossless compression used in tool saves about 90% of the total size input file. When combined with lossy compression is expected to achieve even better results.
