NC格式气象数据无损压缩研究
Research of lossless compression on NC format data of meteorology
摘要
Abstract
A lostless data compression algorithm is proposed, which applies minus computation between close hme span data on ac-count of regulation, applies minus computation again between near points of the same span data, thus value 00 0r FF may occur in stor-age as much as possible; it applies WinRAR tool to compress data lostlcssly. The experimental result illustrates that this method can im-prove lostless compression ratio effectively.关键词
