About Us

xyHt is a group of publications on geospatial topics—for professionals Flatdog Media LOgoand “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?

xyHt signifies a set of coordinates:

x = left-right

y = fore-aft

H = up-down (orthometric height)

t = epoch/time

  • Fleet management, routing, routing grade | Precision agriculture, precision guidance, intelligent transportation systems
  • Precision navigation, robotics guidance
  • Hydrography, bathymetry | Marine/underwater construction surveying
  • Structural monitoring, deflections/seismic, large-motion monitoring
  • BIM, plant and process, facilities, architecture
  • Engineering surveying, construction surveying, machine control, quantities
  • Terrestrial signal-based navigation/guidance systems
  • Indoor signal-based location systems
  • Satellite imagining/photogrammetry | Satellite radar/sensing
  • Airborne, UAS photogrammetry | Airborne, UAS lidar, radar

What happened to Professional Surveyor Magazine?

Flatdog Media published Professional Surveyor Magazine for 30 years. Click 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 prior to April 2013 are on the PSM website – April to June are right here.

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. – See more at: http://www.xyht.com/surveying/about-xyht/#sthash.gs32LUXq.dpuf
