xyHt is a magazine and blog covering geospatial disciplines for professionals and prosumers, published by Flatdog Media.
We print 12 issues of xyHt per year, with two seasonal supplements (sometimes three). All print issues are also available digitally for free, as are our two emailed newsletters: Pangaea and Surveyors’ Field Notes.
A print subscription is free to qualified subscribers in the United States; there is a postage fee for non-U.S. subscribers. Click here for subscription information.

What happened to Professional Surveyor Magazine?
Flatdog Media published Professional Surveyor Magazine for 30 years. Click here for a message from geodesist Dave Doyle and one from our publisher Neil Sandler to read why we retired PSM and created xyHt.
PSM archives from April 2013 to its closing in June 2014 are here on xyHt’s website; earlier archives are on the PSM website.
