To effectively disseminate location-linked information despite the existence of digital walls across institutions, this study developed a cross-institution mobile App, named GeoFairy2, to overcome the virtual gaps among multi-source datasets and aid the general users to make thorough accurate in-situ decisions. The app provides a one-stop service with relevant information to assist with instant decision making. It was tested and proven to be capable of on-demand coupling and delivering location-based information from multiple sources. The app can help general users to crack down the digital walls among information pools and serve as a one-stop retrieval place for all information. GeoFairy2 was experimented with to gather real-time and historical information about crops, soil, water, and climate. Instead of a one-way data portal, GeoFairy2 allows general users to submit photos and observations to support citizen science projects and derive new insights, and further refine the future service. The two-directional mechanism makes GeoFairy2 a useful mobile gateway to access and contribute to the rapidly growing, heterogeneous, multisource, and location-linked datasets, and pave a way to drive us into a new mobile web with more links and less digital walls across data providers and institutions.

GeoFairy2：跨机构的移动网关，用于位置关联的数据以进行原位决策

为了在各个机构之间都存在数字墙的情况下有效地传播与位置相关的信息，本研究开发了一种跨机构的移动应用程序，名为GeoFairy2，以克服多源数据集之间的虚拟空白，并帮助一般用户在原地决定。该应用程序提供一站式服务，提供相关信息，以帮助您立即做出决策。经过测试证明，它能够按需耦合并从多个来源传递基于位置的信息。该应用程序可以帮助普通用户破解信息池之间的数字墙，并充当所有信息的一站式检索场所。对GeoFairy2进行了实验，以收集有关作物，土壤，水和气候的实时和历史信息。而不是单向数据门户，GeoFairy2允许一般用户提交照片和观察结果，以支持公民科学项目并获得新见解，并进一步完善未来的服务。双向机制使GeoFairy2成为有用的移动网关，可以访问快速增长的，异构的，多源和位置链接的数据集并为之做出贡献，并为将我们带入具有更多链接和更少数字墙的新型移动网络铺平了道路数据提供者和机构。
