ground object

In recent years, quantitative remote sensing has become the most significant character of remote sensing science, but the study of quantitative remote sensing can not discard the strong support of ground object spectrum database and the corresponding remote sensing knowledge base and module base.

近年来，定量遥感已经成为当今遥感科学发展的最显著特征，而定量遥感研究离不开地物波谱数据库以及相应的遥感知识库和模型库的有力支持。

Recognition approach of 3D ground object based on Fuzzy Theory

基于模糊理论的地面三维目标识别方法

As we all know the 3D visualization of ground object requires 3D scene with 3D perceptivity.

我们知道，对空间地物进行三维可视化，必须要建立具有三维透视感的三维场景。

By contrast, Chinese often need introduce each ground object or spatial prepositional phrase by a separate verb.

相对于此，汉语通常需要一个动词引出每一个背衬宾语或空间介词词组。
