xyHt is a group of publications on geospatial topics—for professionals and “prosumers”—published by XYHT, LLC.
We’re a source for news and analytics about land surveying, GNSS, UAS, hydrography, 3D imaging, and more (for a full overview of our coverage, scroll past the covers gallery below). We’re based in North America but our eyes and interests are international.
We print 11 issues of xyHt magazine per year, with two seasonal supplements. All print issues are also available digitally for free (check them out here), as are our two emailed newsletters: Pangaea and Surveyors’ Field Notes. All subscriptions are free (unless you live outside the US and want the print magazine, in which case a fee applies).
You can read the bulk of our features here, on xyHt.com. We hope you enjoy our web-exclusive articles, as well. Why not leave us a comment? It’s great to hear from readers, whatever field you’re in.
