xyHt is a group of publications on geospatial topics—for professionals and “prosumers”—published by Flatdog Media.
What does that mean? We’re a source for news and views 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 12 issues of xyHt magazine per year, with two seasonal supplements (sometimes three). All print issues are also available digitally for free (check ‘em out here), as are our two emailed newsletters: Pangaea and Surveyors’ Field Notes. Why not subscribe?
You can read the bulk of our features here, on xyHt.com. We hope you enjoy our web-exclusive articles too! Why not leave us a comment? It’s great to hear from readers, whatever field you’re in. Or, if you’re interested in writing for us, here’s how, below.

What does “xyHt” mean?
It’s all about (you’ve heard this before) location, location, location:
x = left-right
y = fore-aft
H = up-down (orthometric height)
t = epoch/time
