Advanced drainage design, from LiDAR to the machine.

Everything on this page, in every plan: surface drainage, tile drainage and land forming (Beta), built-in public elevation in every supported region or your own GeoTIFF and RTK data anywhere, the water maps, the Drainage simulation (Beta), machine and CAD/GIS exports, branded PDF reports, the 3D view, soil information, project folders on your own computer, the LiDAR Extractor and 24/7 in-app AI support. The Viewer and the calculators need no account.

Never a per-acre fee. Geo-Surface Pro is US$799 a year for one designer, or US$1,198 for 2 designers, US$1,497 for 3 and US$2,394 for 6, billed annually with unlimited fields and acres. Design 640 acres in a year on a single plan and it works out to about US$1.25 an acre; a revised design or the next field adds nothing.

Not currently. Every plan is billed annually, with every current feature included and a 30-day money-back guarantee on your first purchase.

People working on the same projects can. One licence covers one designer plus the staff in the same business who help on the same jobs, for the same clients and crews: a contractor and a staff member designing for the same crew, or a consultant and an assistant working the same client files.

Each person who designs independently needs a licence of their own. Two consultants with their own clients need two. A company whose designers each run their own field crews needs one per designer. A company with offices that each serve their own clients needs one per designer at each office. Duo, Team and Corporate cover this under one annual bill, with each designer on their own login; every user must work for the same company and share its email domain. The administrator signs up, takes the first seat and adds the others from their account page. Not sure how many you need? Ask us.

Yes, with no account. The live demo runs the design tools on a demo field in every supported region, and it opens on your region by itself: Humboldt County, Iowa, Winkler, Manitoba, Holme Fen, England or Moree, Australia, for example. To look at your own field, draw it in the Viewer and fetch the LiDAR there. Every plan also has a 30-day money-back guarantee on your first purchase.

No. Back up the project and send the file: they open it in the Geo-Surface Viewer with no account, and get the whole job, from the runs and grades to the ground and the water maps behind the plan. On a phone or tablet the Viewer can show their position on the plan with GPS.

Google Chrome or Microsoft Edge on a Windows PC or a Mac desktop or laptop, with nothing to install. Those two browsers can save projects straight into a folder on your computer, which is why Safari and Firefox can’t run the design app, and neither can phones or tablets (they run the Viewer). Plan on 8 GB of RAM (16 GB is nicer), a reasonably modern graphics chip and a stable internet connection; a large monitor and a mouse make design work much easier. The simplest check is to open the live demo on the computer you would actually design on.

Yes. Your projects live in a folder you choose on your own computer, each in its own subfolder with its design, elevation, boundary and results. Work saves itself about every 20 seconds while you design, and a project reopens without downloading its elevation again. Back any project up to a single ZIP to move it to another computer or send it on.

Running in the browser also means you are always on the latest version. New tools and fixes arrive the next time you open the app, with nothing to check for, download, uninstall or reinstall.

No. Your field data stays on your computer: the analysis runs inside your browser, the app downloads public elevation and imagery, and your boundaries, surveys and designs stay in a project folder you choose until you export and send them. The optional AI help sends only a privacy-filtered summary, never coordinates, boundaries or elevation.

Yes, from a person as well as the AI. Members have a Member support page with a contact form that comes straight to our team, and member support requests get priority. Send feedback and feature requests there too.

There is also an extensive user manual, open to anyone, with video walkthroughs of many workflows.

Inside the app, built-in AI support is available 24/7: ask how to use a tool, what a warning means or what to do next, and it can take you to the tool or the right section of the manual. From the same panel you can report a problem, request a feature or message our team. With your permission it uses a privacy-filtered snapshot of the open workflow; it never sends field coordinates, geometry, elevation rasters, uploads, file names, report branding or costs, and the conversation is discarded when the page refreshes. AI can make mistakes, so verify field and engineering decisions before acting on them.

Yes. Surface and tile plans go to Ditch Assist as a map layer that lines up under your GPS position, and land forming (Beta) designs export as an AGD design file with your calibration benchmarks, supported by Ditch Assist and other popular machine control systems. Many other grade-control systems can load the plan as a reference: a georeferenced BMP image overlay, DXF line features, or shapefile, KML and CSV. Installable designs are available for Trimble™ and Ag Leader™ displays in Beta: use them only after each run or area is driven or surveyed with RTK and its final grades are reviewed and approved on the display. Every other file is reference only. Test a file on your display before field use.

Yes, for installation. Plan and design from LiDAR, then survey and grade with RTK when the job goes ahead: either run by run as it goes in, or the whole field first so the design is re-checked on surveyed ground.

Land forming is our newest workflow and is still in Beta. It is a focused drain-to-edge tool: pick the edges water may leave by, set a max cut, and solve a design surface that drains to those edges, moving as little dirt as it can find. We are working on updates now that add more land forming design tools and functionality. Some fields need a different workflow, specialised software or a professional designer. Try land forming in the demo, then look at your own field in the Viewer.

Every supported region, with the same membership: the US and Canada, the UK (England, and Scotland where its LiDAR is published), the Netherlands, Belgium (Flanders), Germany (North Rhine-Westphalia), France, Switzerland, Czechia, Denmark, Norway, Finland, Estonia, New Zealand and Australia (coarse 5 m elevation there: fine for surface drainage planning and a first look, too coarse for tile design). Elevation comes from each country’s public LiDAR, and availability depends on the public data in each area: open Supported regions for the source and coverage map of each. Anywhere else, the app works on your own GeoTIFF, RTK survey or existing design. The app works in US customary or metric units, and it is in English only. Prices in the app and the report are in your country’s currency (pounds, euros, kroner, francs, koruna, or Australian, New Zealand, Canadian or US dollars), and reports start on A4 outside North America (Letter, Legal, Tabloid and A3 are there too). Measured soil survey data is built in for US and Canadian fields.
