摘要
空间数据生产中现有资料的分析主要依赖专家决策,主观性较强且执行效率低。本文将空间数据可用性用于数据生产中,通过对空间数据生产密切相关的可用性指标进行评估,准确掌握多源矢量数据的具体差异,辅助制定科学合理的生产方案。试验结果证明,该方法科学有效,在提高数据生产效率、保证数据质量方面,具有一定的实用性。
In the production of vector spatial data,the analysis of available data is an important part.The existing analytical method relies on expert decision which is high-subjectivity and low-efficiency.The paper applies spatial data usability into the analysis of available data.The key elements in vector spatial data production are evaluated though usability measurements which can show the relative difference of multi-source vector spatial data quantitatively.Based on the evaluating result,the applicable production decision can be formulated easily.The experiments indicate that this method holds higher scientificity,efficiency and practicability.
