Start Designing Drainage Systems from LiDAR in Minutes
Geo-Surface Drain Pro pulls LiDAR automatically, calculates best-fit grades, sizes stepped mains, and exports DXF, KML, and shapefiles — all in your browser. No desktop GIS. No steep learning curve.
Auto step-down pipe sizes at every lateral connection, color-coded on the map
Flow paths, ponding risk, depressions, and wetness layers generated in seconds
Best-fit, constant-grade, and freeform grading with depth checks and earthwork estimates
CAD-style dimension lines, labels, arrows, and spacing grids for precise layout
Machine-ready files for AGPS DirtPro, PipeFM, Ditch Assist, and any GIS platform
Hover any line for instant info, click to select — fast navigation on complex designs
Color-coded map view by pipe size with dual-wall pattern and customizable colors
Materials lists, pipe schedules, cost summaries, and custom disclaimers — ready for clients
Place surface inlets on mains with flow rate sizing — automatically factored into pipe calculations
Open your laptop, pull LiDAR for the client's field on the spot, and show them flow paths, ponding risk, and a rough drainage layout before anyone else has even sent a quote. It's the fastest way to build confidence and close the deal — no office time required.

What You Get With Drain Pro
Everything drainage contractors and design professionals need to go from field boundary to build-ready plan — at a fraction of the cost of traditional desktop software.
Stepped Main Sizing
Automatic pipe sizing with step-down calculations at each lateral connection. Size every segment of your mains based on cumulative contributing area — color-coded on the map.
HD Flow & Wetness Mapping
Generate flow paths, depressions, ponding risk, and wetness layers in seconds. See exactly where water moves and accumulates before you design a single line.
Best-Fit Grade Optimization
Terrain profiles with best-fit, constant-grade, and freeform grade simulation. Depth violation checks and earthwork estimation built in.
3D Terrain Viewer
Interactive 3D viewer with terrain exaggeration and drain line overlay — great for client presentations and verifying designs against the landscape.
Professional Reports
PDF reports with materials lists, pipe schedules, cost summaries, and custom disclaimers. Hand clients a polished deliverable with every project.
Export to DXF, KML & Shapefile
Export designs to DXF for AGPS DirtPro and PipeFM, KML for Google Earth and Ditch Assist, plus Shapefile, GeoTIFF, and CSV for any GIS platform.
Included Free: LiDAR Extractor
Every subscriber also gets free access to our standalone LiDAR Extractor—download survey-grade elevation data from US & Canadian sources and export in 7 formats (GeoTIFF, Shapefile, CSV, KML, and more) for use in any GIS or CAD application. Because we know you won't use Geo-Surface for everything.
Check Your Coverage
Geo-Surface Drain Drain Pro uses high-resolution LiDAR data. Use the interactive maps below to verify coverage in your area before signing up.
Complete coverage across southern Manitoba and Ontario, with expanding coverage in Saskatchewan and Alberta. New LiDAR data added regularly.
Use the map above to check coverage in your area. Areas with visible LiDAR hillshade data are available for processing.
Nearly all major agricultural regions covered. From the Red River Valley to Iowa's rolling hills—if you farm it, we can map it.
Use the map above to check coverage in your area. Green overlay = LiDAR available. Transparent (satellite only) = no coverage yet.
