During coursework and research projects, several geospatial algorithms are produced and mentioned by authors in written documents. However, these products often remain unavailable after the end of the projects but could be reused by third parties, providing an improvement in spatial data infrastructure (SDI), reproducibility and open science. Because SDI relies on the sharing of geographic resources, this article focuses on the study of geospatial algorithms. There are studies concerning the

... of academic spatial data infrastructure (ASDI) as a solution to academic resources, but these rarely comprise the publication of algorithms and are mainly aimed at improving systems through functional requirements without considering the requirements of academic users. This study was carried out with the purpose of supporting the sharing of algorithms in an ASDI (www.idea.ufpr.br) created at the Federal University of Paraná, Brazil. Thus, this study aims to characterize the behaviors of academic users regarding their use, storage, sharing and development of geospatial algorithms. For this purpose, a questionnaire was published and received 196 valid responses. The results showed that compared to other interviewees, academics use, develop and share fewer spatial algorithms and have more concerns about citations and fewer concerns about profit. However, these findings do not imply that these users are less productive but rather that their work is different and may or may not rely on the use of algorithms. Furthermore, the results showed more active sharing when authors work with their own algorithms, which could be due to increased security related to the license information, representing important information to be included in geoportals.
