Geo-Surface Canada Edition

Free LiDAR Elevation Viewer & Terrain Mapping Tool for Canada

Instantly explore Canada’s topography with our free online elevation map. Simply click anywhere in Canada to view precise elevation data—1–2 m resolution in LiDAR-covered regions and 30 m resolution elsewhere.

Toggle LiDAR Coverage: Enable the LiDAR Terrain layer in the Base Layer dropdown to see where high-resolution data is available.
Build High-Definition Terrain Overlays: Click Build Elevation Map, draw your area of interest, and generate a stunning 3D-style terrain image.
Flexible Area Sizes: Map anything from a single quarter-section to vast landscapes. Smaller areas reveal subtle elevation changes and terrain details; larger areas provide broad, interactive overviews.

Start your elevation analysis now—no signup required. Harness Canada’s best free LiDAR elevation viewer or go Pro to uncover every ridge, depression, and flow route in seconds. Runs on all devices, but works best on bigger screens!

Looking for More Features? Upgrade to Geo-Surface Professional

Geo-Surface Pro is built for power users who need more than just elevation.

It adds advanced drainage mapping layers, full drainage design tools, and support for importing and exporting data and map files—all in the same easy-to-use web browser interface as the free version.

You get features that normally cost thousands in desktop software—for just $50/month or $499/year per region (currently available regions are US and Canada).

Map Fields or Entire Regions—Up to 1 Million Acres at a Time

Generate Advanced Drainage Layers, Elevation Profiles, and Design Drainage Systems for Any Land Area—Big or Small

Wherever LiDAR elevation coverage is available (that's virtually all of the U.S. and expanding areas of Canada), simply draw around a field, property, or custom area of interest to create multiple high-resolution drainage mapping layers in under 2 minutes.

🚀 Now supporting areas up to one million acres at a time!
Map massive regions in a single request. Capture major flow routes, significant slopes, key depression zones, and general wetness potential areas over massive areas all in your web browser with a few clicks. Export generated layers for further analysis in GIS software.

For field-level mapping (quarter sections, sections, or custom-sized fields), Geo-Surface delivers highly detailed, high-resolution outputs—showing flow paths, depressions, slope variations, and wetness potential down to partial-acre precision.

Whether you're mapping 80 acres or 800,000, Geo-Surface scales to your needs—giving you the critical terrain insights to plan projects, manage drainage and water, and identify key terrain and relief features like never before.

On-Demand Drainage Flow Mapping

At any location with LiDAR elevation coverage (that's all of the US and these areas for Canada), drawing around a field or land area AOI allows you to automatically generate multiple advanced drainage mapping layers.

NOW YOU CAN MAP UP TO ONE MILLION ACRES AT A TIME!

HD Flow is a high-resolution flow mapping layer that shows you exactly how water moves over the land. This is your secret weapon for effective drainage planning! Adjusting the slider let's you see how many acres drain to each flow route segment at the field level, easily identifying not only the best drain placement routes, but also where the most important drains are. On larger regions, you'll see major flow paths, and you can always export the computed flow in KML for deeper anaylsis in GIS software.

Field Depression Mapping

The Depressions map layer (created at the same time as HD Flow) shows you depressional areas within the field or landscape. These are sinks, or low-lying areas that have no natural drainage. Using the on-screen slider, you can adjust the view to see only deeper depressions as required, up to 30cm / ~1ft (export to your GIS software for more detailed analysis). When combined with the HD Flow map, this is often all that is required to export into grade control software like Ditch Assist™ to show you exactly where to make your drains for the most effective surface drainage - remember, whatever you see on the map you can export that view and overlay it on the map in Ditch Assist!

Slope Mask Layer

As you move the slider for the Slope Mask layer, the first areas that become transparent are the flattest parts of the field or project area. As you continue advancing, you'll be left with only the steepest slope regions highlighted. In addition to helping you identify steep areas with high erosion potentials and the best sites for grassed waterways, this layer can also be used to identify the most level sites within an area for future construction and other projects. And, like all the other generated layers, it can be exported for further anaylisis in GIS software when required.

Wetness Potential Mapping

Wetness Potential shows you the areas that are most prone to waterlogging, but not necessarily classified as depressions. When moving the slider from right to left, the first areas highlighted are likely the first that will become waterlogged based on flow and slope characteristics of the land. Wetness potential helps you identify parts of the field that may require more effective drainage, and can be particularly useful when designing tile drainage systems to help identify which areas might require tighter tile spacings.

Users are also applying wetness and depression mapping in residential areas, helping identify homes built on moisture-prone terrain—often linked to basement water issues.

Advanced Drainage Design Tools

Geo-Surface Pro delivers advanced surface and tile drainage design tools—just like high-end desktop software, but in your browser.

Draw or GPS a proposed drain route to instantly view the terrain profile. Add a best-fit or constant-grade line to simulate how your machine control will perform in the field.
See estimated start depths, cubic yards to move, and check grades at a glance. Use connection validation to ensure every lateral joins the main correctly—whether it’s tile or surface drainage.

Go to the field with a plan—not a guess.

Export What You See, Use It Where You Need

Geo-Surface Pro runs entirely in your web browser, so it works seamlessly on any device.

Design drainage systems on your PC or Mac, then open the same project on your phone or tablet in the field—where built-in geolocation helps you follow and stake out your runs with precision.

Easily save and resume drainage design projects anytime.

Need a quick reference layer? Instantly export map images showing whatever’s on your screen—including flow routes, elevation, or design lines—perfect for importing into Ditch Assist™ or other mapping tools.

Works with QGIS, ArcGIS, Google Earth & More

With Geo-Surface Pro, your data is yours to keep.

Need the LiDAR you're viewing in QGIS or ArcGIS? Just one click and it’s downloaded to your hard drive. Export flow routes as KML files—ready for use in any GIS software or for easy viewing in Google Earth or Google Earth Pro. Want to import your depressions layer into QGIS? No problem, just save it to your hard drive! Likewise with the slope and wetness potential layers you generate. It's your data, you own it!

And we’re constantly expanding what you can generate and export, with new layers and features added regularly.
