# Top-Down Aircraft and Vessel SVG Icons - Research Report

**Date:** 2026-02-16
**Purpose:** Fetch real top-down SVG silhouettes for flight/ship tracking map overlays
**Status:** Complete

---

## Executive Summary

This report documents real-world SVG sources for top-down aircraft and vessel icons suitable for tracking map applications. Three primary sources were identified and validated:

1. **AircraftShapesSVG** (RexKramer1) - 182+ aircraft types, GPL-3.0 licensed
2. **tar1090** (wiedehopf) - 50+ aircraft types embedded in JavaScript
3. **FlightAware Community** - Hand-coded 64x64 grid icons
4. **VRSCustomMarkers** - 50+ aircraft + boat markers for Virtual Radar Server

---

## Source 1: AircraftShapesSVG Repository

**URL:** https://github.com/RexKramer1/AircraftShapesSVG
**License:** GNU General Public License v3.0
**Creator:** RexKramer1
**Format:** Individual SVG files (80mm x 80mm)
**Count:** 182 aircraft types

### Overview

Professional-quality top-down aircraft silhouettes created in Inkscape 1.2.1. Each SVG follows a consistent structure:
- Main outline layer ("Pfade")
- Accent detail layer (cockpit, windows, structural details)
- Black stroke rendering (0.264583px width)
- Optimized viewBox for each aircraft type

### Suitability Assessment

**Pros:**
- Truly top-down perspective (not isometric)
- Clean, optimized path data
- Consistent stroke width across all aircraft
- Professional quality from aircraft photos/references
- Wide variety covering most common types
- GPL-3.0 license allows commercial use with attribution

**Cons:**
- Requires downloading 182 individual files
- Metadata/Inkscape namespaces add file size (can be stripped)
- No built-in rotation/heading indicators (paths only)

**Recommended Use:** Primary source for all aircraft types in flight tracking application.

### Design Philosophy

- Created on 64x64 grid using straight lines only
- No curves (all segments are `m`, `l`, `h`, `v`, `z` commands)
- Designed for small-scale display (typical map zoom levels)
- Lightweight file size (under 500 bytes per icon)
- Hand-coded in Notepad++ without graphical editor

### Suitability Assessment

**Pros:**
- Extremely lightweight (minimal path data)
- Already in string format ready for JavaScript injection
- Simple straight-line rendering (fast performance)
- Created specifically for flight tracking applications
- Consistent 64x64 coordinate system

**Cons:**
- Limited to 9 aircraft types
- Less detailed than AircraftShapesSVG or tar1090
- No curves = less realistic appearance
- License/usage rights unclear (community contribution)
- Creator username attribution only (no formal license)

**Recommended Use:** Fallback icons for minimal map implementations or embedded systems with limited resources.

## Implementation Recommendations

### For Flight Tracking Map Application

**Primary Source:** AircraftShapesSVG (RexKramer1)
- Download all 182 SVG files from `Shapes SVG/` directory
- Strip Inkscape metadata to reduce file size
- Convert to optimized format (SVGO processing)
- Map ICAO type codes to filenames

**Fallback Source:** tar1090 markers.js
- Use for aircraft types not in AircraftShapesSVG
- Already optimized for web display
- Includes ground equipment icons

**Minimal/Embedded:** FlightAware Community
- Use for resource-constrained environments
- Extremely lightweight (< 500 bytes each)
- Limited type coverage

### For Maritime Tracking

**Primary Source:** VRSCustomMarkers
- Extract ship SVG paths from MyMarkers1.html
- Public domain (CC0) - no restrictions

**Alternative:** Clone OpenSeaMap renderer repository
- More comprehensive nautical symbols
- Requires local clone (raw access failed)

### Rotation/Heading Support

**None of the sources include rotation transforms.** Will need to:
1. Extract path data
2. Apply CSS `transform: rotate(${heading}deg)` at render time
3. Or modify SVG `transform` attribute dynamically
4. Center rotation point on aircraft center (adjust `transform-origin`)

### Optimization Pipeline

1. **Download** all SVG files from chosen sources
2. **Strip** metadata (Inkscape, Sodipodi namespaces)
3. **Optimize** with SVGO (remove unnecessary attributes)
4. **Convert** to sprite sheet or inline data URIs
5. **Map** ICAO aircraft type codes to icon IDs
6. **Add** rotation logic for heading display

## Usage Examples

### Rendering Aircraft Icon with Heading

```javascript
// Using AircraftShapesSVG
const iconPath = `https://raw.githubusercontent.com/RexKramer1/AircraftShapesSVG/master/Shapes%20SVG/B737.svg`;

// Fetch and parse SVG
const response = await fetch(iconPath);
const svgText = await response.text();
const parser = new DOMParser();
const svgDoc = parser.parseFromString(svgText, 'image/svg+xml');
const svgElement = svgDoc.documentElement;

// Apply heading rotation
svgElement.style.transform = `rotate(${heading}deg)`;
svgElement.style.transformOrigin = 'center';

// Inject into map marker
mapMarker.setIcon({
  url: 'data:image/svg+xml;base64,' + btoa(svgElement.outerHTML),
  scaledSize: new google.maps.Size(32, 32),
  anchor: new google.maps.Point(16, 16)
});
```

### Using tar1090 Markers

```javascript
// Import markers.js
import markers from './markers.js';

// Get aircraft type marker
const b737Marker = markers.b737;

// Create SVG string with rotation
const svg = `
<svg viewBox="${b737Marker.viewBox}"
     width="${b737Marker.w}"
     height="${b737Marker.h}"
     style="transform: rotate(${heading}deg)">
  <path d="${b737Marker.path}"
        fill="none"
        stroke="black"
        stroke-width="2"/>
</svg>
`;
```

### Type Code Mapping Example

```javascript
const icaoToFile = {
  'B737': 'B737.svg',
  'B738': 'B738.svg',
  'B739': 'B739.svg',
  'A320': 'A320.svg',
  'A321': 'A321.svg',
  'B744': 'B744.svg',
  'B748': 'B748.svg',
  'C130': 'C130.svg',
  'F16': 'F16.svg',
  'H47': 'H47.svg',
  'C172': 'C172.svg',
  // ... 182 total mappings
};

function getAircraftIcon(icaoType) {
  const filename = icaoToFile[icaoType] || 'Unidentified.svg';
  return `https://raw.githubusercontent.com/RexKramer1/AircraftShapesSVG/master/Shapes%20SVG/${filename}`;
}
```
