地表覆盖自动解译方案在地理国情普查项目中的应用

在地理国情普查项目中,地表覆盖提取工作主要依赖人工解译和自动解译两种作业方式,实践证明,自动解译在一定程度上能够提高地表覆盖提取的工作效率,在地理国情普查项目中自动解译工作占30%的工作量,本文以易康软件为例,结合地理国情普查工作实际,详述地表覆盖自动解译方案。

The Application of Automatic Interpretation of Surface Coverage in Geographic Conditions Survey

In the project of geographic conditions survey , surface coverage extraction mainly relies on two kinds of operation mode . One is artificial interpretation , the other is automatic interpretation .Practice has proved that automatic interpretation can improve the surface coverage extraction efficiency in a certain extent .Automatic interpretation work is accounted for 30% of the workload in the geographic conditions survey project .In this paper, we use eCognition software as an example , which is combined with the geographic conditions of census work practice , to detail land cover automatic interpretation scheme .
