基于FME的土地卫片图斑批量自动预判定方法

An Automatic Pre-judgment Method for Map Spots of Satellite Land Image Based on FME

随着土地卫片执法工作从常规方式向信息化转变,如何在实际工作中快速高效准确利用好各类空间数据,做好土地卫片图斑前期梳理分析工作,已成为自然资源执法领域一个无法规避的技术问题。为此,基于FME多源集成式数据处理平台,通过对用地审批、土地利用现状等基础数据进行格式转换,加工整合,叠加分析,为区县卫片执法技术人员设计了一个数据处理模型。通过实际工作的检验,该数据模型可以大大减轻工作量,有效提高工作效率,对土地卫片执法工作具有较强的实用意义。

With the transformation for law enforcement of satellite land image from conventional methods to informatization,how to quickly,efficiently and accurately use various spatial data in actual work,and do a good job in the early-stage sorting and analysis of lsatellite land image spots has become a difficult problem in the field of natural resources law enforcement.To this end,based on the FME multi-source integrated data processing platform,a data processing model has been designed for law enforcement personnel of satellite land image in the districts and counties through format conversion,processing integration,and overlay analysis of basic data such as land use approval and land use status.Through practical work,tests prove that this data model can greatly reduce workload,effectively improve work efficiency,and has strong practical significance for law enforcement work of satellite land image.
