to see Drain Pro in action
See What's New in v2.3Setup & Analysis
Start every project with clean, trusted elevation. Drain Pro automatically pulls LiDAR where available, builds high-resolution terrain layers, and shows you exactly how water wants to move—before you draw a single line.
Complete Design Workspace
Three focused tabs—Setup, Design, Export—guide you from boundary to final plan in a single, consistent interface.
Automatic LiDAR Import
Instantly fetch LiDAR-based elevation for supported regions in Canada and the US, or drop in your own DEMs when you've got them.
High-Resolution Terrain Display
Elevation colorization dialled for drainage work, so subtle slopes and problem spots stand out immediately.
Flow Path Mapping
Generate precise flow routes to see how water actually drains and where mains and surface ditches should go.
Wetness Potential Layers
Topographic wetness and ponding tools flag the chronically wet acres that are stealing yield.
Depression & Ponding Detection
Automatically identify low pockets and isolation spots to prioritize cuts, tile, or outlets.
Intelligent Design Tools
Draw once, trust it. Drain Pro enforces connections, grades, and hierarchy so your designs behave like a real system, not a scribble on an aerial.
Interactive Design Tools
Draw mains, submains, and laterals directly on the map with live LiDAR-based profiles and instant feedback. Hover any line for quick stats, click to select.
Automatic Network Hierarchy
Clean IDs and structure (mains, submains, laterals) handled for you — no more manual naming chaos.
Connection Validation
Snapping, depth checks, and warnings ensure everything ties together and drains the right way.
Best-Fit Grade Optimization
Best-fit, constant-grade, and freeform grade tools lock in slopes, starting depths, and outlet conditions that work in the real world. Earthwork estimates and depth violation warnings built in.
Stepped Main Sizing
Automatic step-down pipe sizes at every lateral connection, based on cumulative contributing area. Each segment color-coded on the map so you can verify the design at a glance.
Pattern Tile Layout
Generate systematic laterals with customizable spacing and automatic connection to mains. Adjust spacing grids with angle-pick from existing lines.
CAD-Style Annotations
Dimension lines, text labels, arrows, rectangles, filled areas, and exclusion zones — all on a toggleable layer included in project backups.
Surface Inlets
Place surface inlets on mains with flow-rate sizing. Inlet flow is automatically factored into downstream pipe calculations.
Pipe Size Color Mode
View your entire design color-coded by pipe size with customizable colors. Dual-wall pipes display a distinctive block pattern.
Grid Overlay
Customizable spacing grid you can snap to the bearing of any existing line — helps with precise manual lateral placement.
Export & Reporting
When the design is done, Drain Pro gives you machine-ready files and professional client deliverables — no extra software needed.
Professional PDF Reports
One-click reports with map overviews, pipe schedules, stepped segment breakdowns, materials lists, cost summaries, and customizable disclaimers — ready to hand to clients.
OptiSurface Land Forming Integration
Design tile drainage for the final surface, not the current one. Export your LiDAR to OptiSurface AGS format, design land forming there, then import the optimized surface back into Drain Pro. Your tile layout will account for planned grades and earthwork—so the system functions correctly after land forming is complete. Install dirt first, tile second, with confidence the depths and slopes match the real terrain.
DXF, KML & Shapefile Export
Export to DXF for AGPS DirtPro and PipeFM, KML for Google Earth and Ditch Assist, Shapefile for any GIS platform, or load files on a tablet for GPS-guided installation.
Full Project Backup & Restore
Save the entire project—boundaries, LiDAR, analysis layers, and designs—so you can revise, duplicate, or prove work anytime.
Simple, Predictable Pricing
Unlimited projects under one annual license, so you can scale your service without watching the meter.
Included Free: LiDAR Extractor
We know you won't use Geo-Surface for everything—so every Drain Pro member gets free access to our standalone LiDAR Extractor tool. Download survey-grade LiDAR data from US and Canadian government sources and export in 7 formats (GeoTIFF, Shapefile, CSV, KML, ASCII Grid, Surfer GRD, AGS) with flexible resolution and coordinate systems.

Coverage & Data Sources
Geo-Surface is designed to take advantage of modern elevation data infrastructure:
United States: Uses high-quality elevation data such as USGS 3DEP where available, enabling detailed drainage and terrain mapping for most agricultural regions.
Canada: Supports LiDAR and elevation coverage where provincial and federal datasets exist, with coverage expanding over time.
Custom Data: Already have your own RTK surveys or DEMs? Import supported GeoTIFFs to run the same analysis and design workflows on your own elevation data.
In every case, Geo-Surface helps you turn raw data into something usable: flow paths, depressions, slope masks, wetness potential, and buildable drainage layouts—without writing scripts or operating a GIS stack.
(Actual coverage and performance depend on availability and quality of source elevation data in your region.)
Why Browser-Based Drainage Design Software
Geo-Surface Drain Pro runs in a modern web browser — but it's not "lightweight" software. It's serious design capability without the friction that usually comes with desktop GIS.
- No installation — open your browser and start designing. Works on Windows, Mac, and tablets
- Design anywhere — at the office, at the kitchen table with a client, or at a trade show pulling live LiDAR
- Fast onboarding — consistent interface with built-in user manual, video tutorials, and documented workflows
- Always up to date — new features roll out automatically, no reinstalls or license upgrades
- Field-ready — open designs on a tablet, combine with GPS for on-site layout and verification
The tool that replaces the back-of-the-truck laptop running outdated desktop GIS.
