Grade Checker: Capture Point A

Before You Begin

How It Works

Walk or drive your proposed route while this app captures GPS positions and fetches LiDAR elevations. Export as XYZ Raw file for Drain IQ.

Important Limitations

LiDAR may be inaccurate in ditches, near culverts, or in vegetation
Best results in open areas with bare soil
Ground conditions may have changed since capture

Pro Tip

After designing in Slope-IQ, use Auto Height Calibration at your start point to align GPS to LiDAR data.

Grade Checker

What This Does

Quickly estimate the average grade between two points using LiDAR elevations. Great for field scouting and preliminary assessments.

Use With Caution

LiDAR cannot see through water or dense vegetation
NOT suitable for measuring grades between culvert inverts
For culverts and precise work, use RTK survey equipment

Best Used For

Open fields, bare soil areas, and preliminary grade estimates. Use the result as your target gradient in Ditch Assist DIG.
