A Tampermonkey userscript for Waze Map Editor (WME) that displays official Slovenian house numbers from EProstor directly on the WME map.
This helps editors quickly add and verify house numbers without manually opening external GIS portals.

After installing the script and opening WME, you’ll find a new “SL-HN” tab under the Scripts section in the left sidebar.

1. Select a street segment.
2. Click “Load visible selection.”
3. The script fetches nearby address points (via EProstor WFS).
4. Circles appear on the map:
   • 🟢 Green: House numbers that belong to the selected street
   • ⚪️ Gray: House numbers for nearby streets not matching the selected one
   • 🟥 Red: A conflict — an existing house number differs from the EProstor value nearby (on the selected or other visible streets, possibly wrong or incorrectly cased, e.g. 4A instead of 4a).

You can:

• Toggle the layer on/off.
• Show only missing house numbers.
• Adjust the search buffer (default: 200 m).

• Mismatched street names:
  If houses that should be on the selected street show up as gray, the street name in Waze may not exactly match the official one in EProstor (different capitalization, spelling, or incorrect naming).
  → Fix the street name in Waze before adding the house numbers.

• Red conflicts (wrong or mismatched HNs):
  Red circles appear when a different house number already exists nearby on the same street.
  This usually means:

  • The number in WME is wrong, or
  • There’s a case mismatch (e.g. 4A in WME vs 4a in EProstor).
    These should be checked and corrected manually in Waze.

• Limited scope:
  Currently only supports Slovenian EProstor data (GML/WFS format).

• Accuracy:
  EProstor coordinates are typically precise, but always double-check before adding or adjusting HNs.

• Development status:
  This script is still in development. Expect occasional bugs or temporary UI glitches.
  Please report any issues or improvements.

1. Install the Tampermonkey extension.
2. Click here to install the script.
   Tampermonkey should automatically detect and prompt for installation.
3. After installation, reload the Waze Map Editor (production or beta).
4. Look for the SL-HN tab under the Scripts section in the sidebar.

• Uses WME SDK (getWmeSdk) for tab registration and notifications.
• Loads EProstor data via GM_xmlhttpRequest (WFS GetFeature → GML).
• Supports coordinate reprojection (proj4js) from EPSG:3794 → EPSG:3857.
• Saves layer visibility and buffer distance in localStorage.
