各种以地图为中心的网络服务便利了公民的生活。网络地图应用已经存在了很多年。随着WebGIS技术的不断简化和完善，基于地图的WebGIS服务变得越来越重要。这类服务的数据质量保证是一项重大挑战。由于许多这样的应用程序密集地使用开放数据，因此需要专注于开放解决方案的方法。这项工作提出了一个数据质量的概念，这是基于内在的和可比的方法。OpenStreetMap（OSM）允许内部数据评估。此外，它还被用作公共部门信息开放数据层质量评估的参考数据集。基于等距点（EDP）的统计数据可以过滤掉低质量的开放数据特征。数据类型模型执行OSM数据的库存。通过比较光栅网络地图切片文件大小和计算简化的数据质量指标，可以指定可接受的数据质量级别。质量保证Web服务的可嵌入实例包含具有可接受质量的数据功能。这项工作提供了在自由许可证下部署此类服务所需的所有软件和数据。具体的说明允许用户在其平台上采用建议的解决方案。一些通用用例说明了引入的共享Web服务的优点。
Various map-centered web services facilitate citizens' lives. Web-map applications exist for many years already. Due to simplification and improvement of technologies supporting WebGIS, map-based services become more popular and important nowadays. Data quality assurance for such services is a significant challenge. Since many of such applications intensively use open data, approaches focused on open solutions are required. This work proposes a data-quality concept, which is based on intrinsic and comparable approaches. OpenStreetMap (OSM) allows intrinsic data evaluation. Moreover, it is used as a reference dataset for quality assessment of public-sector-information Open Data layers. Equidistant point (EDP)-based statistics enables to filter out low-quality Open Data features. A data-type model carries out the inventory of OSM data. The comparison of raster web-map tile file sizes and calculation of a simplified data quality indicator make it possible to specify acceptable data quality levels. Embeddable instances of quality assurance web services incorporate data features with acceptable quality. This work provides all required software and data for the deployment of such services under liberal licenses. Concrete instructions allow users to adopt the proposed solutions for their platforms. Some generic use cases illustrate the advantages of the introduced shared web services.
