Requirements

The following scripts must be installed and active (Tampermonkey loads them via @require):

• WazeWrap
• Turf.js
• WME Utils - Bootstrap

---

Installation

1. Install Tampermonkey for your browser
2. Click the install link on Greasy Fork
3. Open WME — the FC Layer panel will appear in the sidebar

---

Usage

• The layer activates automatically when WME loads (minimum zoom level 11)
• Toggle visibility using the FC Layer checkbox in the WME layer switcher, or with the power button in the sidebar panel
• Use the state dropdown in the sidebar to filter to a single state
• Check Hide Streets to hide FC 7 (local road) segments and reduce clutter at lower zoom levels
• The sidebar panel displays the data source, permission level, and any notes for the currently selected state

---

Contributing

Pull requests are welcome. When adding or updating a state:

1. Add an entry to STATE_SETTINGS in WME-FC-Layer.js
2. Add the state's ArcGIS @connect domain to the userscript header
3. Implement getFeatureRoadType and getWhereClause using existing states as a reference
4. Test at multiple zoom levels and verify color coding against the state DOT source
