WME Quick HN Importer – Slovenia 🇸🇮

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.

🧭 How It Works

After installing the script, you'll see a new SL-HN tab in the left sidebar of WME.

Basic workflow

1. Select a street segment
2. Click "Load selected street"
3. The script retrieves nearby address points via EProstor OGC API Features
4. Circles appear on the map and indicate:

Color	Meaning
🟢 Green	House numbers belonging to the selected street (primary or alternate)
🟠 Orange	House numbers belonging to other streets
🔴 Red	Conflicts, e.g. a different nearby existing house number
⚪ Faded green	Already present in WME

👉 Adding house numbers

Click any circle to instantly add that house number to the nearest matching segment.

No manual typing is needed — just click.

⚙️ Options

• Toggle the layer visibility
• Show only missing house numbers
• Show only the selected street
• Adjust the buffer distance (default: 500 m)

🆕 Street Name Validation (v2.1.0)

The script now includes street name mismatch detection to help you fix incorrect street names.

How it works

When you load addresses, the script analyzes official street names from EProstor and compares them with the selected WME segment:

Indicator	Meaning
⚠️ Yellow warning	WME street name doesn't match any official names
💡 Green suggestion	Fuzzy match found (typo, abbreviation, or diacritic difference)
✓ Checkmark	Street name matches the current WME segment
→ Arrow	Click to apply this street name to the segment

One-click street name fix

1. Select a segment with an incorrect street name
2. Load the area
3. Find the correct official name in the list
4. Click → to instantly update the segment's street name
5. Circles turn green immediately!

Features

• Fuzzy matching: Detects typos, missing diacritics (e.g., "Šmartinska" vs "Smartinska"), and common abbreviations (c. → cesta, ul. → ulica)
• Copy to clipboard: Click 📋 to copy any official street name

⚠️ Notes & Gotchas

🔤 Street name mismatches

If house numbers appear 🟠 orange instead of 🟢 green, the WME street name may not match the official EProstor one.

New in v2.1.0: The script now warns you about mismatches and suggests corrections! Look for the yellow warning box and use the → button to fix street names with one click.

🔴 Red conflicts

Red numbers appear when:

• Another house number exists nearby but differs
• Wrong casing (4A vs 4a)
• Misplaced numbers on the wrong segment

Always verify manually.

🟠 Segments without a street name

If you select a segment without a street name:

• All markers become 🟠 orange (because no match is possible)
• Use the street list to apply the correct name with one click

📡 Accuracy

EProstor coordinates are normally precise, but always visually verify before adding.
