Benefits and performance

Trimble’s water management solutions aim to help you make the best use of this invaluable resource. Here are a few of the benefits the WM-Survey II app brings to farmers around the world.

Perfect for surveyors of any experience level

Intuitive workflows guide users and reduce survey errors, making it an ideal tool for beginning water management work.

Customisable for your needs

WM-Survey II becomes even more powerful by adding our advanced feature set for terrace, waterway and rice levee system designs, as well as generating 3D surface control files and navigational guidance lines.

Easily and automatically create basic designs, including 3D control and feature line guidance files

Terraces and waterways are designed to divert water off a field so that soil erosion and crop loss due to water ponding is reduced. Terraces have a high side that prevents water from running over the top of it, while also typically sloping to the side to divert water into a waterway or ditch plug socket along the edge of a field. Waterways transport water off a field to a designated plug socket.

The Terrace & Waterway Design solution allows the user to easily and automatically create a basic terrace or waterway design in just five steps. The 3D control files and feature line guidance files for compatible Trimble displays are also auto-created, allowing land forming work to begin straightaway - no more waiting for designs to come back from the office. Farmers can now conduct their own maintenance, saving money on contractors by extending the life expectancy of terraces and waterways while preventing up to 5% yield loss in terraced fields.

Optional subscription

Auto-create rice levees based on desired specifications and field elevation

Rice is grown in a consistent depth of water to help limit weeds, reduce insect infestations and boost overall crop health. Because fields have a minimum slope to one corner for drainage, rice levees are used to hold water at a constant depth across the elevation gradient of the field. As the water reaches the plug socket of the field, it is then pumped back to the top to restart the process.

The Levee Design subscription feature uses a four-step guided workflow to auto-create rice levees based on desired specifications and elevation across a field. Upon creation of the design, feature line guidance files are also exported and available for use in levee installation. Minimise yield loss from weather-delayed planting by getting to work implementing the designs straightaway. Eliminate the hours or days waiting for a designer to get back to you.

Surveys measure different areas and help to determine what solutions could be applied.

When paired with a sufficiently accurate GNSS receiver, the WM-Survey II app easily records elevation points across a field to generate a topographic map. This topographic map or survey, can be exported to other software programs and used to create designs for land forming, grading, surface drainage and sub-surface drainage projects.

Topographic data can be analysed 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
