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.<\/jats:p>","DOI":"10.3390\/ijgi10010001","type":"journal-article","created":{"date-parts":[[2020,12,22]],"date-time":"2020-12-22T12:42:28Z","timestamp":1608640948000},"page":"1","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["GeoFairy2: A Cross-Institution Mobile Gateway to Location-Linked Data for In-Situ Decision Making"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9810-0023","authenticated-orcid":false,"given":"Ziheng","family":"Sun","sequence":"first","affiliation":[{"name":"Center for Spatial Information Science and Systems, Department of Geography and Geoinformation Science, George Mason University, Fairfax, VA 22030, USA"}]},{"given":"Liping","family":"Di","sequence":"additional","affiliation":[{"name":"Center for Spatial Information Science and Systems, Department of Geography and Geoinformation Science, George Mason University, Fairfax, VA 22030, USA"}]},{"given":"Sreten","family":"Cvetojevic","sequence":"additional","affiliation":[{"name":"Center for Spatial Information Science and Systems, Department of Geography and Geoinformation Science, George Mason University, Fairfax, VA 22030, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7985-4775","authenticated-orcid":false,"given":"Zhiqi","family":"Yu","sequence":"additional","affiliation":[{"name":"Center for Spatial Information Science and Systems, Department of Geography and Geoinformation Science, George Mason University, Fairfax, VA 22030, USA"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1109\/MPRV.2008.80","article-title":"Openstreetmap: User-generated street maps","volume":"7","author":"Haklay","year":"2008","journal-title":"Pervasive Comput.
