The reason to develop another stereographic projection package arises from the recent use of Python as an exclusive programming language within the ArcGIS\u00ae environment. This permits a more flexible approach for the development of tools with very intuitive GUIs, and also allows the user to take full advantage of all potential GIS mapping processes. The core of this new projections toolbox is based on the capability to easily apply and compare most of the commonly used statistical methods for cluster and girdle analysis of structural data. In addition to the well-known Fisher, K-means, and Bingham data elaborations, a completely new algorithm for cluster analysis and mean vector extraction (Mean Extractor from Azimuthal Data), was developed, thereby allowing a more reliable interpretation of any possible structural data distribution. Furthermore, as in any other GIS platform, users can always precisely correlate each single projected data point with the corresponding geographical\/locality position, thereby merging or subdividing groups of structural stations with a simple selection procedure. ArcStereoNet also creates rose diagrams, which may be applied not only to fault\/joint planes orientation data, but also for the analysis of 2D microstructural fabric parameters. These include geometrical datasets derived from the minimum bounding approach as applied to vectorized grains in thin sections. Finally, several customization settings ensure high-quality graphic outputs of plots, that also allow easy vector graphics post-processing.<\/jats:p>","DOI":"10.3390\/ijgi10020050","type":"journal-article","created":{"date-parts":[[2021,1,26]],"date-time":"2021-01-26T08:29:16Z","timestamp":1611649756000},"page":"50","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["ArcStereoNet: A New ArcGIS\u00ae Toolbox for Projection and Analysis of Meso- and Micro-Structural Data"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5802-6922","authenticated-orcid":false,"given":"Gaetano","family":"Ortolano","sequence":"first","affiliation":[{"name":"Department of Biological, Geological and Environmental Sciences, University of Catania, Corso Italia, 57, 95129 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4461-7745","authenticated-orcid":false,"given":"Alberto","family":"D\u2019Agostino","sequence":"additional","affiliation":[{"name":"Department of Biological, Geological and Environmental Sciences, University of Catania, Corso Italia, 57, 95129 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Pagano","sequence":"additional","affiliation":[{"name":"Department of Biological, Geological and Environmental Sciences, University of Catania, Corso Italia, 57, 95129 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6102-4204","authenticated-orcid":false,"given":"Roberto","family":"Visalli","sequence":"additional","affiliation":[{"name":"Department of Biological, Geological and Environmental Sciences, University of Catania, Corso Italia, 57, 95129 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3600-7856","authenticated-orcid":false,"given":"Michele","family":"Zucali","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Milano, Via Mangiagalli, 34, 20133 Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1802-8207","authenticated-orcid":false,"given":"Eugenio","family":"Fazio","sequence":"additional","affiliation":[{"name":"Department of Biological, Geological and Environmental Sciences, University of Catania, Corso Italia, 57, 95129 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ian","family":"Alsop","sequence":"additional","affiliation":[{"name":"School of Geosciences, University of Aberdeen, Aberdeen AB24 3UE, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4595-150X","authenticated-orcid":false,"given":"Rosolino","family":"Cirrincione","sequence":"additional","affiliation":[{"name":"Department of Biological, Geological and Environmental Sciences, University of Catania, Corso Italia, 57, 95129 Catania, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,26]]},"reference":[{"key":"ref_1","first-page":"257","article-title":"PT-path reconstruction via unraveling of peculiar zoning pattern in atoll shaped garnets via image assisted analysis: An example from the Santa Lucia del Mela garnet micaschists (northeastern Sicily-Italy)","volume":"83","author":"Ortolano","year":"2014","journal-title":"Period.
