Drain-IQ — Help & User Guide

Overview

Drain-IQ is a field-ready web app that puts a complete, pre-generated LiDAR stack at your fingertips—elevation, contours, depression/ponding depths, wetness index, and flow routes—hosted behind your own custom URL. No software to install, no login. Open the link on any device and your layers stream instantly.

It's the modern replacement for paper maps and waiting on consultants: trace routes, check grades and depths, add to a design, and export georeferenced files in minutes—right from the field.

Watch This First - Main Features & Workflow Explainer

Interface & Navigation

Drain-IQ features a modern, responsive interface optimized for both desktop and mobile devices.

Sidebar (Desktop & Tablet)

• Toggle sidebar: Click the hamburger menu (top-left) to open/close the sidebar.
• The sidebar is organized into collapsible sections (Fields, Layers, Tools, Export, etc.).
• Click section headers to expand/collapse them.
• On desktop, the sidebar floats over the map with a clean card design.

Floating Quick Actions

Quick access buttons appear at the bottom of the screen:

• Layers — Quick layer toggle popover
• GPS — Enable location tracking

Fields

Select the field you want to work on. Each field loads its own set of layers and export files.

Switching Fields

• Click the Field Selector button at the top of the sidebar (shows current field name with )
• Choose a field from the dropdown list
• The map automatically recenters and loads the boundary
• Fields with an Offline badge are saved for offline use

Last Field Memory

• Your last-selected field is remembered and loads automatically on your next visit

2D / 3D View Modes

Switch between flat 2D maps and immersive 3D terrain visualization.

Toggle View Mode

• Use the 2D / 3D toggle switch in the sidebar header
• 2D Mode: Traditional map view with layers, perfect for planning and measurements
• 3D Mode: Perspective terrain view with elevation exaggeration, ideal for visualizing slopes and drainage patterns

3D Mode Features

• Multi-directional hillshading shows terrain relief from all angles
• Elevation coloring highlights high and low areas
• Rotate: Right-click/two-finger drag to change viewing angle
• Tilt: Adjust pitch to see terrain from different perspectives
• Ponding overlay syncs with 2D ponding slider

Note: Profile chart and some drawing tools are disabled in 3D mode. Switch back to 2D for full functionality.

Layers

Toggle visibility and adjust settings for each analysis layer. Layers are grouped by type with visual indicators showing which are active.

Field Boundary

• Shows your supplied or digitized boundary.
• Used for exports and fit-to-view.

Elevation

• LiDAR elevation surface displayed to emphasize the highest and lowest parts of the field.
• Use this for general terrain context and spot checks.

Contours

• Pre-generated KML contour sets based on field elevation range (e.g., 6 in, 1 ft, 2 ft, 5 ft, 10 ft).
• Very flat fields will see 6in, 1ft, 2ft contours. Moderately flat fields will have 1ft, 2ft, and 5ft contours. Rolling lands have 2ft, 5ft, and 10ft contours. And very hilly land has 5ft, 10ft,, and 15ft contours.
• Click a contour set to load. Only one contour layer can be loaded to the map at once

Flow Lines

• Display the major natural overland flow routes in the field.
• Modeled using 'fill-and-spill' (where low areas fill up, where will the water go next?) method.
Following natural flow routes where possible results in efficient drains with less earth to move for surface draind, and easier installs for tiles.
• Use the slider to filter minimum contributing acres and identify the most important drains on the field.

Ponding Risk

• Identifies areas prone to standing water based on slope, contributing area, and depression likelihood.
• Usually the priority areas to target with surface or targeted tile drainage.
• Move the Overlay intensity slider right to emphasize depressions, and to the left to expand to ponding-prone areas on flat fields.
• Blue = low risk, Yellow/Orange = moderate, Red = high risk.

Depressions

• Uses a pit-fill algorithm that identifies areas with no natural drainage outlet.
• Creates a "filled" seamless surface where all depressions are filled, then compares it to the natural surface—the difference reveals true depressions.
• Shows areas where water naturally accumulates with no way to drain without intervention.
• Blue = shallow depressions, Red = deep depressions.

Wetness Index

• Topographic Wetness Index (TWI) predicts likelihood of areas being wet based on relief. Blue = wetter-prone, Red = drier.
• Highlights subtle ridges and raised areas on flat fields, and more pronounced features on rolling ground, as relatively drier zones (note: less reliable on very flat terrain).
• Useful to guide targeted tile placements on more rolling land - try to get tiles into the blue and green-blue areas.

Mark Elevations

Click anywhere on the map to place an elevation marker showing the precise elevation at that point.

How to Use

• Open the Mark Elevations section in the sidebar
• Click or tap on the map to place markers
• Each marker displays the elevation in feet
• Use Undo to remove the last marker
• Use Clear to remove all markers

Best Uses

• Compare elevations of ridges, draws, and low spots
• Evaluate potential outlet locations
• Check grade between two points
• Verify LiDAR accuracy against known benchmarks

Quick Profiler

Draw a line across your field to sample elevations and instantly view an elevation profile chart with auto-computed "best-fit" drainage lines. These fits are intended for planning and information purposes only: Best-Fit Surface (red dashed, ≥0.05% grade) and Best-Fit Tile (green dashed, ≥0.10% grade with 2 ft cover). Before installing, all routes should be surveyed and confirmed with an RTK-grade control system.

Workflow

1. Open Quick Profiler section (drawing is armed automatically). Desktop: Click to drop points, double-click to finish. Touch: Long-press to drop each point—a single tap will close the line immediately.
2. The profile chart expands from the bottom showing:
   • Ground surface (black filled area)
   • -1 ft Guide (grey dashed, enabled by default)
   • Best-Fit Surface (red dashed, ≥0.05%, enabled by default)
   • -3 ft and -5 ft Guides (grey dashed, click legend to enable)
   • Best Fit Tile (green dashed, ≥0.10% with 2 ft cover, click legend to enable)
3. Resize the chart: Drag the handle at the top of the chart up/down to adjust height, or click to close
4. Use Reverse Outlet if your profile appears to run "uphill"
5. Press Add to Design to save the route to Quick Designer

Profile Chart Controls

• Clear – Remove current profile and chart
• New – Draw another profile
• Reverse – Flip inlet/outlet direction
• Add to Design – Save route to Quick Designer
• Undo – Remove last addition from plan

Chart Guide Lines

Click items in the chart legend to show/hide guide lines. Your preferences are saved automatically:

• -1 ft, -3 ft, -5 ft Guides: Visualize cut depths (1ft shows by default)
• Best-Fit Surface: Minimum 0.05% grade surface drain (shown by default)
• Best Fit Tile: Minimum 0.10% grade with 2ft cover (click legend to enable)

Tip: For surface drain planning, hide the 3ft, 5ft, and tile guides to focus on shallower cuts.

Quick Designer

Quick Designer lets you turn one or more profiler routes into a working plan. Think of it as a simple design board: every route you Add to Design from Quick Profiler is stored, tallied, and displayed on the map as a thick purple line with arrows pointing toward the outlet. With the tab open, a stats box appears in the lower-right corner showing combined lengths, averages, and totals.

Plan Basics

• Save Design – download your current plan as design.json for backup or sharing. This also lets you pause work and continue later.
• Load Design – import a saved design.json back into the app to continue editing, or share it with someone else so they can open your custom URL and view your exact plan.
• Clear Current Plan – wipe the slate clean and remove all design lines.

Important: This is a web app – designs are only saved for the current session. If you refresh the page or navigate away, your plan will be lost. Always use Save Design if you’ll need it again!

Exports

• Export Design Report (PDF) – snapshot of your field with design lines plus full statistics. Useful for planning discussions or even as supporting documentation for permit applications.
• Export Plan to KML / CSV / XYZ – take your design into Google Earth, spreadsheets, or GNSS tools.
  • KML: overlay your plan in Google Earth or other mapping apps.
  • CSV: simple table with latitude, longitude, and elevation columns.
  • XYZ: can be imported into Ditch Assist (Layers → Import XYZ). This allows Slope-IQ to follow your planned grade without re-driving the survey. Important: use caution – always run Auto Height Calibration to align GPS elevation with LiDAR. Recommended for excavators, not surface implements.

On-map Styling

• Design lines are shown in purple with arrows pointing to the outlet.
• The Designer stats box (lower-right) updates live as you add or remove routes.

Best Use

Use Quick Designer to sketch out a drainage plan before going to the field. Share the saved plan with a custom operator, agronomist, or crew. It’s a quick way to communicate intent and test “what-if” layouts without extra trips to the field.

Print & Export

Export maps and data for reporting, machine control overlays, or GIS analysis.

Which export should I use? PDF for reports, JPG+JGW/BMP+BPW for machine overlays, KML for Google Earth, GeoTIFF/SHP for GIS.

Geolocation (GPS)

Track your real-time location in the field and navigate to specific areas.

Enabling GPS

• Click the GPS button (floating button or sidebar)
• Grant location permission when prompted
• Your position appears as a blue dot on the map
• Accuracy circle shows GPS precision

GPS Features

• Enable Tracking – Show your current position
• Follow Mode – Keep map centered on your location as you move
• Heading Indicator – Shows direction of movement

Best Practices

• iOS/Safari: Enable "Precise Location" in Settings → Privacy → Location Services
• Android/Chrome: Use "High accuracy" mode in Location settings
• For best accuracy, use outdoors with clear sky view
• GPS accuracy is typically 5-15m; use RTK for construction-grade precision

Using Offline

Save field data to your device for use without internet connection. Ideal for working in remote areas with poor cell coverage.

How to Save for Offline

1. Select your field from the dropdown
2. Wait for all layers to finish loading (you'll see them appear on the map)
3. Scroll to the bottom of the sidebar
4. Click Save for Offline
5. Wait for "Saved for offline ✓" confirmation
6. The field will show an Offline badge in the field list

Offline Status Indicators

• Available offline ✓ – Field is fully cached
• Offline badge – Shows next to cached fields in the list
• Status updates automatically when you switch fields

What's Cached

• ✅ Field boundary, elevation raster, flow lines
• ✅ Ponding risk, depressions, and wetness index
• ❌ Contours (not cached due to large file size)
• ✅ App interface and tools

Best Practices

• Pre-load before leaving: Save while on WiFi, before heading to the field
• Keep session open: Don't close the browser tab or refresh the page until you're back online
• Use installed app: Install as PWA for more reliable offline persistence
• Clear when done: Use Clear Offline to free up device storage

Install as an App

Installing Drain-IQ as a home-screen app gives you a full-screen experience, quick launching, and more reliable session persistence while you’re in the field.

• You may see an install prompt on first load. If not, there’s also an Install App button under About & Help.
• Installing does not change the offline behavior: you still need to Save for Offline while online and keep the session open.
