X-PAD Survey for Android presents a new way of working, based on the most technologically advanced platform for mobile devices.

For the first time software designed for topographic survey and stake out in the field is available on Android, with a wide range of user-friendly features. Partnered with GeoMax survey instruments, X-PAD Survey for Android will change your way of working forever.

In addition to the well established Windows® Mobile version of X-PAD for Android. This version brings additional benefits that improve, simplify and speed up all survey activities in the field.

  • Google® Map: X-PAD allows you to integrate the Google maps in every phase of the work, in survey, in stake out and in the graphic CAD.&
  • Augmented Reality: X-PAD uses the camera of the data logger to display the points and drawing with augmented reality. Panning the camera around, you can see where the plotted points are, even if they are underground.

“We have been using the Zenith35 Rover and Base and the Zoom90 Robotic Total Station for the past 2 years and we think they are great. We mainly work in the civil construction sector on greenfield projects building new residential subdivisions. The package we purchased was competitive in price and also had the backing/confidence of technology tried and tested by Hexagon.” – Orrin Julian, Civil Survey & Design

“The GeoMax X-Pad Survey software is great to use, simple and intuitive and the search function really speeds up the process, it took us about 30mins of training to be up and ready to work.” – Toby Stoff, Clark Fortune McDonald
