Class location, High Consequence Area determination, MAOP records GIS, and integrity-management spatial joins — fully automated against the regulatory data sources your auditors care about.
Pipeline integrity engineers spend more time assembling regulatory data than analyzing it. Every PHMSA inspection cycle re-runs the same spatial joins by hand.
49 CFR §192.5 class location recomputed manually from Census blocks each year
HCA buffer + structure count typed into spreadsheets for thousands of segments
MAOP records GIS trapped in Excel with no spatial index
Pipe-and-cathodic-protection joins done in legacy desktop GIS
Eight workflows that automate the spatial side of PHMSA Part 192 / 195 compliance, integrity management, and class-location reviews.
| Workflow | Name & what it automates | Time saved |
|---|---|---|
| #223 | Class Location Determination Sliding-mile structure count against Census blocks → Class 1/2/3/4 classification per segment | — |
| #224 | HCA Identification (192.903) Population & ID-site buffer analysis → segment-level HCA flag with audit trail | — |
| #225 | MAOP Records GIS Pressure-test and design records spatially indexed against pipeline centerlines | — |
| #226 | Cathodic Protection Survey QA Close Interval Survey + DCVG result rasters joined to pipe segments with anomaly flagging | — |
| #228 | Right-of-Way Encroachment Recent imagery + LiDAR change vs. easement polygons → encroachment alerts | — |
| #231 | Hydrostatic Test Section Builder Elevation-profile-aware test segment definition to keep within MAOP limits | — |
| #234 | PHMSA Annual Report Pack Auto-assembled mileage / class / HCA / incident report extracts ready for submission | — |
| #67 | Access Road Routing Slope cost surface for inspection-vehicle access to remote valves and metering stations | — |
Modeled on a 4,500-mile interstate transmission operator with annual class-location reviews and biennial integrity assessments.
| Metric | Manual / current tooling | GeoDataConverter |
|---|---|---|
| Class-location review cycle | 12–16 weeks | 1 day |
| HCA recomputation cost | $210,000 / year | $24,000 / year |
| MAOP spatial join time per system | 3–4 weeks | Hours |
| PHMSA submission rework cycles | 2–3 | 0–1 |
Every class-location and HCA computation is stamped with the input dataset version, the buffer parameters, the Census vintage, and the run-time, and the resulting polygons are reproducible bit-for-bit. When the inspector asks "how did this segment become Class 3 in 2024 but Class 2 in 2023?" you re-run the workflow with the older Census and produce both answers in minutes.
Send us 250 miles of centerlines. We'll return current class location, HCA flags, and MAOP-segment counts within 48 hours, with the audit trail attached.
