气候类型的空间数据编码方案及应用——以柯本气候分类为例

Spatial Data Encoding and its Application to Koppen's Climatic Classification

介绍了空间数据的组织、表达和编码等基本原理,并提出在柯本气候分类中运用空间数据编码的方案:以传统的气候分类指标作为编码依据,采用2字节的无符号整型数记录气候编码,共5位数,首位为主码,表示气候带;2 4位为子码,分别代表气候类型、所在大洲和地区;末位为描述码,用于描述气候特征。

Based on some essential principle of organizing, expressing and encoding spatial data, the paper shows a method of using spatial dada encoding in Koppen＇ s climatic classification, whose encoding basis is the traditional climatic classification indexes, encoding name is a five-bit number which the first bit means climatic belt, the second bit means climatic type, the third bit means continent, the forth bit means area and the last bit expresses climatic peculiarity.
