Mine Windrow Analysis
This tool is designed to enhance windrow monitoring. Given only a 2D road centreline and a recent LiDAR dataset, the tool creates profiles at set intervals and scans each profile for elevation changes, testing them for criteria matching windrow tops and toes.
Key metrics including height, width, and slope are calculated from these points. Each profile is classified using pass or fail criteria and attributed with calculated values.
The tool relies on a simple arrangement of rise-overrun analysis over perpendicular hairs to detect slope changes. These are then filtered further to check for potential windrow and mini-windrow shapes. This output is taken through a quick result sampling (to check detection success) and reporting is run using client parameters.
Aerometrex provides clients a full report that includes a brief, shapefile attribute key, and images. Additionally, the company provides shapefiles of:
Road segments - a newly calculated adjusted centreline for the road, broken into interval segments, with elevation and slope information for each segment.
Windrow lines - contains elevated lines for each windrow including width, height, and compliance
Road profiles - contains elevated lines for each road section (road edge to road edge, exclusive of any mini windrows detected), with road width information and compliance (plus some other beta information)
