There is a wealth of data on air pollution within several users' reach, including modelled concentrations and depositions as well as observations from air quality stations. However, data integration to perceive spatial and temporal trends at the national level is a complex undertaking. The difficulties are mainly related to the data sources (many files with a lot of information and in different formats). In addition, the processing of this data is time-consuming and impractical when the time period under analysis increases. Furthermore,the processing of spatial-temporal data requires the use of multiple specific tools, such as geographic information systems software and statistical, which are not readily accessible to non-specialised users. The proposed solution is to develop libraries that are responsible for aggregating different types of data related with pollution. In addition to allowing the integration of different data, the libraries are also the basis for developing web applications. The libraries allow the collection of data made available by the Portuguese Environment Agency (APA) and official modelling results for Europe. The applications developed will extend the libraries to allow data processing and representation through Dashboards. These Dashboards provide access to non-specialised users, namely regarding the trends of pollutants in each region. The implemented libraries allow the development of projects that would need access to the same data sources. These Dashboards allow for simplified access to data and for studies that have so far been beyond the reach of researchers.
翻译:在若干用户范围内有大量关于空气污染的数据,包括模拟浓度和沉积以及空气质量站观测,然而,为了解国家一级空间和时间趋势而进行的数据整合是一项复杂的工作,主要与数据来源有关(许多文件含有大量信息和不同格式的资料);此外,当分析所涉时间段延长时,这些数据的处理既费时又不切实际;此外,空间时空数据的处理需要使用多种具体工具,例如地理信息系统软件和统计,这些工具不便于非专门用户使用;提议的解决办法是建立图书馆,负责汇集与污染有关的不同类型数据;除了允许整合不同数据外,图书馆也是开发网络应用程序的基础;图书馆允许收集葡萄牙环境署提供的数据,以及欧洲的正式建模结果;开发的应用程序将扩大图书馆,允许通过Dashboards进行数据处理和代表;这些Dashboard机向非专门用户提供接入,即有关污染物趋势的无障碍访问;拟议的解决办法是建立图书馆,负责汇集不同种类的与污染有关的数据;此外,图书馆也是开发网络的基础;这些图书馆还允许对数据库进行简化访问,从而使研究人员能够访问这些来源获得数据。
