摘要
本文评估面向统计+地理信息的可视化平台可用性,通过对比分析不同典型的可视化平台功能,选择出各具功能特色的典型平台ECharts和Power Map(地图增强版),之后基于模糊层次分析法建立可用性评价指标体系,采用模糊综合评价法量化评价平台可用性。实验选取典型统计+地理信息实例,结果表明,ECharts整体略优于Power Map,差别在于ECharts能支持较多类型的统计数据可视化,且可视化形式相对丰富,而Power Map在表达地理数据上有优势,支持三维地图表达,制作相对简单。
This study aims to evaluate the usability of different visualization platforms for the representations of statistical and geographic data.Firstly,two platforms with different functional characteristics,i.e.ECharts and Power Map,were selected by comparing and analyzing the functions of different typical visualization platforms.Then,an indicator system for usability evaluation was established based on the fuzzy analytic hierarchy process.The usability of different platforms was quantitatively evaluated by fuzzy comprehensive evaluation method.A typical example with statistics and geographic data was used in the evaluation experiment.The experimental results showed ECharts was slightly better than Power Map as a whole.The difference was that ECharts can support the visualization representation requirements for more complex and various types of statistical data,and could generate more types of visualization product.Power Map was suitable for the representation of geographic data and could support the three-dimensional map representation,and it is ease of operation.
