摘  要:
从遥感数据中获取地面目标分布的专题信息(如林地覆被/森林类型等),是林业资源数据的主要获取手段之一。在对林业资源遥感数据获知的过程中,林业遥感数据的尺度问题是研究的一个重要内容。忽视林业资源遥感的尺度效应,使得对林业资源观测难以获得精确的数据。林业资源遥感数据在时间上、空间上以及应用上都有尺度问题。本文从尺度的定义、林业遥感尺度问题以及尺度转换方法等方面来研究林业资源遥感信息的尺度问题。

摘  要:
Gaining the special data (forest land cover/forest type, etc. ) of ground object distribution from the remote sensing data is one of the main means incdlecting resource data of forestry. During collecting the resource data of remote sensing of forestry, the study of remote sensing scale of the forestry is an important content. Ignore the effect of remote sensing scale of forestry resource, it is difficult to get the accurate data from the resource observation of the forestry. Remote sensing data of forestry have scale problems in time, space and applications. The remote sensing scale issues of forestry were studied from definition of scale, remote sensing scale issue of forestry and method of scaling, etc.
