Elevation & Drainage Analysis

Tile Drainage Planning

Precision elevation models and drainage analysis to optimize tile drainage system design.

Tile drainage planning drone survey

Better Drainage Starts with Better Data

Tile drainage is one of the most significant infrastructure investments you can make on your Alberta farm. Getting the design right is critical — and that starts with accurate elevation data. Our drone surveys produce high-resolution digital elevation models (DEMs) that show every contour, slope, and low spot in your field with centimetre-level precision.

Traditional land surveys for tile drainage planning are time-consuming and expensive, often requiring a survey crew to spend days in the field collecting elevation points. Our drone surveys cover the same area in a fraction of the time, capturing millions of data points that produce a more detailed and accurate elevation model than traditional methods.

The resulting DEM clearly shows natural drainage patterns, identifies where water accumulates, and reveals the subtle grade changes that determine optimal tile placement. Your drainage contractor can import our data directly into their design software to plan tile lines, calculate grades, and estimate material requirements with confidence.

Whether you're planning a new tile drainage system or expanding an existing one, our aerial elevation surveys give you the data foundation you need for a successful project. We also provide drainage flow analysis maps that help you and your contractor visualize how water moves across your field before and after tiling.

How It Works

1

Aerial Survey

We fly your fields with RTK-corrected GPS to capture thousands of elevation data points per acre.

2

DEM Generation

Imagery is processed into a precise digital elevation model showing every contour and drainage pathway in your field.

3

Design Support

The DEM is exported in formats compatible with tile drainage design software so your contractor can plan optimal tile placement.

Key Benefits

High-resolution digital elevation models (DEMs)
Centimetre-level RTK accuracy for grade planning
Natural drainage pattern identification
Low-spot and water accumulation mapping
Integration with tile drainage design software
Faster and more affordable than traditional land surveys

Frequently asked questions

How accurate is the elevation model from a drone survey?

With RTK ground control: +/-5-10 cm vertical accuracy across the field. That's well within tolerance for designing tile-drainage gradients (typically 0.1-0.3% slope on main lines).

What deliverables do you provide for tile-drainage planning?

Digital terrain model (GeoTIFF + IMG), contour map, surface flow accumulation map, and a low-spot polygon layer. All GIS-ready for tile-drainage design software.

Can you survey wet or recently-flooded ground?

Yes - drone surveys are ground-condition agnostic. We capture exactly the surface that needs to drain, with no risk of getting stuck.

How many acres can you survey for drainage planning per day?

1,500+ acres at 2.5 cm/pixel and +/-5 cm vertical accuracy. Larger fields (10,000+ acres) take multiple days but the day-rate scales linearly.

Does the survey help with regulatory drainage approvals?

Yes. The accurate DEM and surface flow map support drainage application packages for Alberta's regional drainage authorities. Engineers can directly import the DTM into design software.
