By anchoring medias to geographic coordinates, it is possible to design immersive experiences remotely, without necessitating an in-depth knowledge of the context. However, the creation of such experiences typically requires complex programming tools that are beyond the reach of mainstream users. We introduce BiodivAR, a web cartographic tool for the authoring of location-based AR experiences. Developed using a user-centered design methodology and open-source interoperable web technologies, it is the second iteration of an effort that started in 2016. It is designed to meet needs defined through use cases co-designed with end users and enables the creation of custom geolocated points of interest. This approach enabled substantial progress over the previous iteration. Its reliance on geolocation data to anchor augmented objects relative to the user\u2019s position poses a set of challenges: On mobile devices, GNSS accuracy typically lies between 1 m and 30 m. Due to its impact on the anchoring, this lack of accuracy can have deleterious effects on usability. We conducted a comparative user test using the application in combination with two different geolocation data types (GNSS versus RTK). While the test\u2019s results are undergoing analysis, we hereby present a methodology for the assessment of our system\u2019s usability based on the use of eye-tracking devices, geolocated traces and events, and usability questionnaires.<\/jats:p>","DOI":"10.3390\/ijgi12020061","type":"journal-article","created":{"date-parts":[[2023,2,10]],"date-time":"2023-02-10T04:48:03Z","timestamp":1676004483000},"page":"61","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["BiodivAR: A Cartographic Authoring Tool for the Visualization of Geolocated Media in Augmented Reality"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5325-3824","authenticated-orcid":false,"given":"Julien","family":"Mercier","sequence":"first","affiliation":[{"name":"Media Engineering Institute (MEI), School of Engineering and Management Vaud, HES-SO University of Applied Sciences and Arts Western Switzerland, 1400 Yverdon-les-Bains, Switzerland"},{"name":"Lab-STICC, UMR 6285, CNRS, Universit\u00e9 Bretagne Sud, F-56000 Vannes, France"}]},{"given":"Nicolas","family":"Chabloz","sequence":"additional","affiliation":[{"name":"Media Engineering Institute (MEI), School of Engineering and Management Vaud, HES-SO University of Applied Sciences and Arts Western Switzerland, 1400 Yverdon-les-Bains, Switzerland"}]},{"given":"Gregory","family":"Dozot","sequence":"additional","affiliation":[{"name":"Media Engineering Institute (MEI), School of Engineering and Management Vaud, HES-SO University of Applied Sciences and Arts Western Switzerland, 1400 Yverdon-les-Bains, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9062-8453","authenticated-orcid":false,"given":"Olivier","family":"Ertz","sequence":"additional","affiliation":[{"name":"Media Engineering Institute (MEI), School of Engineering and Management Vaud, HES-SO University of Applied Sciences and Arts Western Switzerland, 1400 Yverdon-les-Bains, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4936-7079","authenticated-orcid":false,"given":"Erwan","family":"Bocher","sequence":"additional","affiliation":[{"name":"Lab-STICC, UMR 6285, CNRS, Universit\u00e9 Bretagne Sud, F-56000 Vannes, France"}]},{"given":"Daniel","family":"Rappo","sequence":"additional","affiliation":[{"name":"Media Engineering Institute (MEI), School of Engineering and Management Vaud, HES-SO University of Applied Sciences and Arts Western Switzerland, 1400 Yverdon-les-Bains, Switzerland"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,9]]},"reference":[{"key":"ref_1","unstructured":"Rubin, J., and Chisnell, D.
