在过去的二十年中，建立的空间数据基础架构（SDI）解锁了异质地理空间数据集。欧盟启发了指令奠定了泛欧SDI的基础，其中成千上万的公共部门数据提供商可以将其数据（包括传感器观察）提供，可用于跨境和跨域重复使用。同时，SDI不可避免地会采用新技术和标准，以最适合目的，并以最佳方式解决不同利益相关者（政府，企业和公民）的需求。 SDI利益相关者提出的一些反复出现的技术要求包括：（i）需要采用宁静的建筑；以及（ii）替代（gml）数据编码，例如JavaScript对象符号（JSON）和二进制交换格式； （iii）采用基于异步的出版物订阅的消息传递协议。新成立的OGC标准感觉API对Inspire进行调查特别有趣，因为它共同解决了这三个主题。在本手稿中，我们对OGC Sensorthings API标准的必要步骤提供了合成的观点，可以将其视为符合Inspire指令造成的法律义务的解决方案。我们分享有关应对有关的事情的看法：（i）数据编码； （ii）将Sensorthings API用作下载服务。
Spatial Data Infrastructures (SDI) established during the past two decades unlocked heterogeneous geospatial datasets. The European Union INSPIRE Directive laid down the foundation of a pan-European SDI where thousands of public sector data providers make their data, including sensor observations, available for cross-border and cross-domain reuse. At the same time, SDIs should inevitably adopt new technology and standards to remain fit for purpose and address in the best possible way the needs of different stakeholders (government, businesses and citizens). Some of the recurring technical requirements raised by SDI stakeholders include: (i) the need for adoption of RESTful architectures; together with (ii) alternative (to GML) data encodings, such as JavaScript Object Notation (JSON) and binary exchange formats; and (iii) adoption of asynchronous publish-subscribe-based messaging protocols. The newly established OGC standard SensorThings API is particularly interesting to investigate for INSPIRE, as it addresses together all three topics. In this manuscript, we provide our synthesised perspective on the necessary steps for the OGC SensorThings API standard to be considered as a solution that meets the legal obligations stemming out of the INSPIRE Directive. We share our perspective on what should be done concerning: (i) data encoding; and (ii) the use of SensorThings API as a download service.
