WM-Survey II App

The WM-Survey II™ app is the only tool you need to get started with water management activities on the farm. This free-to-download mobile application makes it easy to create basic field surveys for use in water management activities. Compatible with any Android phone or tablet (version 9.0 or higher), as well as the GFX-750 display, users can connect any GNSS receiver they own to their device to create topographic maps for use in a variety of surface and subsurface applications.

Key Benefits

  • Intuitive workflows guide users and reduce errors
  • Easily accessible entry-level application for beginning water management work
  • Save money by using the survey equipment you already own
  • Save time with quick and easy verification of surface or tiling designs

Why Conduct a Survey?

A survey creates an elevation map of a field that is the first step in any water management decision making. It provides a general lay of the land, allows measurement of different areas, and helps determine what solutions may be applied.

When paired with a sufficiently accurate GNSS receiver, WM-Survey II allows the easy recording of elevation points across a field to generate a topographic map. This topographic map, or survey, can be exported to other software programs and then used to create land forming and grading designs as well as surface and sub-surface drainage designs.

Topographic data can be analyzed to determine:

  • Water flow direction into and out of survey region
  • Most efficient water removal route
  • Most efficient water retention location
  • Ideal terrace location
  • Ideal waterway location
  • Ideal location for gates or pumps with drainage tile projects
  • Ideal location and size of watersheds for compliance
  • Best starter hole locations for drainage installation

Project Verification

WM-Survey II makes verification at the end of a water management project fast and easy. Simply import the design file that was used and then walk or drive across the surface of the field to compare the designed elevation to the actual work that was performed. If any problem areas are identified, simply drop a pin to revisit at a later date.
