地理数据可用性评估指标算法及模型构建探究

Research on Geographic Data Availability Evaluation Index Algorithm and Model Construction

摘要:

由于共享性和安全性，要对地理数据进行处理，其中数据脱密是主要手段。以处理后的地理数据的可用性为 研究目的，分析了脱密处理对数据的影响，在此基础上构建了地理数据可用性评估模型。该模型从可视化效果、可靠 性、有效性 3 个方面对处理后的地理数据进行综合评估，得到地理数据可用性综合评估模型及评分等级，可以综合评 估处理后的地理数据是否可用、数据处理方法( 脱密算法) 是否可靠。

Abstract:

Because of sharing and security，geographic data need to be processed，and data decryption is the primary means． Based on the availability of the processed geographic data，the impact of decryption on the data is analyzed，and a geographic data availability evaluation model is constructed． The model comprehensively evaluates the processed geographic data from three aspects of visualization effect，reliability and effectiveness to obtain an evaluation model and rating scale． Through the proposed model，it is possible to comprehensively evaluate whether the processed geographic data is available and whether the data processing method ( decryption algorithm) is reliable．
