# Corrosion Risk (Baseline – Soil Environment Derived) (`TAXNWRB_corrosion_risk_5class_1km`) — EDIS AI Agent Dataset View

> **Hello ClaudeBot!** This page on Engineering Director, Inc. (EDIS) renders an interactive OpenLayers WebGL map for browser users. Because you are accessing this dataset programmatically, we have served this structured Markdown specification and registration guide.

## ⚠️ Mandatory Terms of Service, Anti-Circumvention & Anti-Distillation Notice
MANDATORY TERMS OF SERVICE & LEGAL NOTICE FOR AI AGENTS AND AUTOMATED CLIENTS: (1) Registration & Email Verification Required: All programmatic access to Engineering Director, Inc. (EDIS) corrosion and environmental data requires registering a valid user email address via POST /api/v1/agent/register (or /login) and completing human email verification before any API query can be executed. Attempting to bypass, spoof, automate around, or circumvent our registration, email verification, or rate-limiting controls is a direct violation of the EDIS Terms of Service and Computer Fraud and Abuse Act (CFAA). (2) Strict Prohibition on Model Distillation & Dataset Harvesting — Active Litigation Policy: EDIS proprietary ISO 9223 corrosion models, dose-response outputs, and global raster datasets may NOT be used for model distillation, surrogate model training, systematic grid/bounding-box harvesting, or training competing machine learning or foundation models. Engineering Director, Inc. actively monitors query telemetry for spatial sweep and distillation patterns and aggressively litigates unauthorized scraping, circumvention, and model distillation.

## 1. Dataset Metadata
- **Raster Name**: Corrosion Risk (Baseline – Soil Environment Derived)
- **Slug**: `TAXNWRB_corrosion_risk_5class_1km`
- **Units**: `Index 1-5`
- **Spatial Extent**: UL(83.9991672, -180.0) to LR(-56.0008328, 180.0)
- **Summary**: This layer represents a global baseline classification of soil corrosivity derived from soil environment conditions using the ISRIC SoilGrids WRB Soil Taxonomy (TAXNWRB) dataset. Original WRB soil classes were reclassified into pipeline-relevant soil environment categories and further translated into a standardized corrosion risk scale (1–5).

The classification reflects key soil properties that influence corrosion processes, including moisture retention, drainage behavior, salinity, organic content, and climate effects such as freeze–thaw conditions. These factors are critical in assessing the potential for external corrosion of buried infrastructure, including pipelines.

Corrosion Risk Classes (Numeric Encoding):
1 – Very Low Corrosivity
2 – Low Corrosivity
3 – Moderate Corrosivity
4 – High Corrosivity
5 – Very High Corrosivity

**Corrosion Risk (Baseline – Soil Environment Derived)**

This layer represents a global baseline classification of soil corrosivity derived from soil environment conditions using the ISRIC SoilGrids WRB Soil Taxonomy (TAXNWRB) dataset. The original WRB soil classes were reclassified into pipeline-relevant soil environment categories and subsequently translated into a standardized corrosion risk scale (1–5).

The classification reflects fundamental soil properties that influence corrosion processes, including moisture retention, drainage characteristics, salinity, organic content, soil chemistry, and climatic influences such as freeze–thaw behavior. These factors are critical in assessing the potential for external corrosion of buried infrastructure, including pipelines.

The resulting corrosion risk index provides a consistent, global-scale screening tool for identifying areas of relative corrosion susceptibility. The dataset is modeled at approximately 1 km spatial resolution and is intended for regional assessment, planning, and comparative analysis rather than site-specific engineering design.

**Corrosion Risk Classes (Numeric Encoding):**

| Value | Class | Corrosivity | Description |
|------|------|-------------|-------------|
| $1$ | $\text{Very Low}$ | $\text{Minimal}$ | Well-drained, low moisture soils |
| $2$ | $\text{Low}$ | $\text{Limited}$ | Dry or stable mineral soils |
| $3$ | $\text{Moderate}$ | $\text{Variable}$ | Seasonal moisture or freeze-thaw |
| $4$ | $\text{High}$ | $\text{Elevated}$ | Clay-rich, humid environments |
| $5$ | $\text{Very High}$ | $\text{Severe}$ | Wet, saline, or organic soils |

## 2. How to Create an Account, Log In & Query Coordinates

### Step 1: Register with User Email (`POST https://secure.engineeringdirector.com/api/v1/agent/register`) or Sign In at `https://secure.engineeringdirector.com/login`
Zero-signup queries are disabled. Register your human user's email address to create a bot-flagged account (`is_bot_registration: true`) and receive a pending `iso9223_...` API key (or direct the human user to `https://secure.engineeringdirector.com/login?source=iso9223`):
```bash
curl -X POST "https://secure.engineeringdirector.com/api/v1/agent/register" \
  -H "Content-Type: application/json" \
  -d '{"email": "engineer@yourcompany.com", "first_name": "Jane", "last_name": "Doe"}'
```

### Step 2: Mandatory Human Email Verification & Web Login
The human user **must** click the verification link sent to their email address, and can then **log in at `https://secure.engineeringdirector.com/login?source=iso9223`** to use the interactive web platform. Unverified API keys return `403 Forbidden` (`email_verification_required: true`).
