一种优化的土地利用遥感更新解译流程与效果分析

An Optimized Process of Land Use Remote Sensing Renewal Interpretation And Its Effect Analysis

在常规的土地利用遥感更新解译流程中,存在缺少有效控制漏判环节、解译操作效率较低等不足。对其中的相关原因进行了分析,并在实践的基础上提出了一种优化的更新解译流程。该流程从提高解译人员的专注度以及增加编辑操作自动化的角度出发,对常规流程的部分环节进行了优化,尤其是将原先综合查找变化的流程优化为按类型拆分土地利用图层、按类型查找变化,从而解决漏判的问题;同时新设立一些必要的环节,将原先的一些繁杂的人工操作交由应用软件执行。应用实践结果表明,这一优化的土地利用遥感更新解译流程,在将各环节的任务简洁化的同时,提高了解译的针对性和操作的自动化,有助于减少解译过程中的漏判和编辑错误。虽然解译环节有所增加,但整体解译时间有所减少,解译效率得到提高。

In the conventional land use remote sensing updating and interpretation process,there are some shortcomings such as lack of effective control omission and low efficiency of interpretation operation.In this paper,the relevant reasons are analyzed,and on the basis of practice,an optimized update interpretation process is proposed.In order to improve the concentration of interpreters and increase the automation of editing operations,the optimization process optimizes part of the routine process,especially the original comprehensive search process is optimized to split the land use layer by type and search the change by type,so as to solve the problem of missing judgment.At the same time,some necessary links are newly established,and some complicated manual operations are handed over to application software.The application practice shows that this optimized land use remote sensing update interpretation process not only simplifies the tasks of each link,but also improves the pertinence of understanding translation and the automation of operation,which helps to reduce the missing judgment and editing errors in the interpretation process.Although the interpretation process is increased,the overall interpretation time is reduced and the interpretation efficiency is improved.
