摘要
为保证林地数据真实性、准确性和时效性,降低林地年度变更及森林图斑复位调查数据配发工作量,在2016年度林地变更调查成果和贵州省第四次森林资源普查成果基础上,利用ArcGIS建模技术和Python语言完成小班图形边界衔接、数据结构和代码之间的转换工作,实现了全省林地变更调查期初数据配发以及森林资源图斑复位调查数据配发,较常规数据处理方法效率有一定地提高,为其它数据之间的转换提供可借鉴的经验。
In order to ensure the forest land data authenticity, accuracy and timeliness, reduce forest annual change and forest figure spot reset survey data with the effort, in 2016 the annual forest land change survey results and on the basis of the fourth census of forest resources in guizhou, using ArcGIS modeling technology and the Python language to complete a small graphic boundary cohesion, the data structure and code conversion between work, implements the province's forest land change survey initial data distribution and figure spot reduction of forest resources survey data, the conventional data processing methods have certain to improve efficiency, for other data conversion between provides referential experiences.
