Three ways to fix wet ground
Move the water on the surface, drain it with tile, or reshape the field itself
All three start from the same elevation map — built-in LiDAR or a DEM you upload. See where the water sits, design the fix, and hand over a client-ready PDF. It's one product: everything below is included, no tiers, no add-ons.
Surface drainage
Draw mains and laterals right on the imagery and they name themselves (S1, S1-L1…). Auto Best Fit solves the grade, or take the wheel with Guided and Freeform. A live profile chart shows cut and fill down the run, and depth flags light up the moment you break your limits. Map the ponding and flow paths first, so your ditches follow the real dirt.
Tile drainage
Mains and laterals with a real naming hierarchy (T1, T1-L1…). Manning's equation sizes every pipe from contributing area, coefficient, and grade, and the Auto Size wizard steps the diameter up at each lateral junction — manual override on any segment. The ladder runs 3 to 48 inch, laterals snap to the main, and defaults set per line or field-wide.
3D landforming Beta
Pick your outlets — the boundary edges where water's allowed to leave — set your max cut, and hit Solve. Every acre sheds to those outlets, no ponding left, checked on the finished surface. Fill comes from nearby high ground, so most of the field barely gets touched. Honest audited volumes, haul-distance bands, and machine-ready files out — including Ditch Assist AGD with benchmarks.
All three are in the one membership — sign up before September 1, 2026, and lock in US$499/yr for as long as you remain a member. After that, new memberships are US$799/yr. No tiers, no add-ons, no per-acre fees. Get Pro at US$499/yr Try the live demo first

Find the wet acres and test the fix yourself.
Farmer / landowner
Plan surface drainage and straightforward tile yourself instead of hiring it out — and when a bigger job needs a contractor, understand the quote and keep it honest.

Quick answers before you dig in
What is Geo-Surface Pro?
It's drainage design software for farm ground — surface drainage, tile, and 3D landforming, all three in one tool that runs right in your browser. Draw a field boundary, pull in the elevation, and design the fix. Works across the US and Canada.
Does it really do 3D landforming as well as tile?
Yep. The landforming designer grades your field so it sheds to the edges you pick, fills the low spots, and hands you three design models to try — and it's built to be easy, not a science project. Straight talk on scope: it's a drainage-first grading designer, not a specialist multi-plane optimizer like OptiSurface. For most fields it gets you there; for the really tricky ones, that's still their game. See how it stacks up against OptiSurface.
How much does it cost?
US$499 a year until September 1, 2026 — after that it's US$799/yr for new signups. Sign up at $499 and that stays your renewal price for as long as you keep your membership. It's unlimited acres and unlimited fields — no per-acre fees, ever — and 30 days money-back if it's not for you. See the full pricing.
Does my field data get uploaded anywhere?
No. Your survey points, boundaries, and designs are processed right in your browser, on your own computer — interpolating survey data and running the water analysis never sends your field data to a server. Projects save to a folder you pick on your own machine, and you decide what leaves it.
Can I try it before I pay?
Yep, two ways, both free and neither needs an account. The live demo drops you into a real field — Humboldt County, Iowa, or Winkler, Manitoba and Chatham-Kent, Ontario in Canada — where you can pull the elevation, map the water, and draw a design. The free Viewer lets you look at LiDAR terrain on any field and open plans people share with you. No signup, no email.
Do I need to install anything?
Nope. It runs in Chrome or Edge on whatever computer you've already got — nothing to download, nothing to maintain. Elevation data's built in for the US and Canada, or you can bring your own GeoTIFF or survey points.
