Vectorizing Maps and Diagrams: Geographic & Technical Illustration

Why Vectorize Maps and Diagrams?

Maps and diagrams need to be:

Scalable from reports to posters

Editable for updates and translations

Print-ready at any resolution

Consistent across all materials

Vector format delivers on all counts.

Types of Graphics to Vectorize

Geographic Maps

City and regional maps

Transit and subway maps

Custom illustrated maps

Simplified location maps

Flowcharts & Processes

Business process diagrams

Decision trees

Workflow illustrations

System architectures

Technical Diagrams

Circuit diagrams

Mechanical drawings

Scientific illustrations

Organizational charts

Infographics

Data visualizations

Comparison graphics

Timeline illustrations

Statistical charts

The Vectorization Process

Step 1: Source Quality

Use highest resolution available

Scan physical maps at 300+ DPI

Capture screenshots at native resolution

Prefer clean, simple original designs

Step 2: Preparation

Increase contrast for clearer lines

Remove noise and artifacts

Crop to relevant area

Consider grayscale for cleaner traces

Step 3: Convert

1. Upload to [VectoSolve](/png-to-svg)

2. AI traces lines and shapes

3. Download editable SVG

Step 4: Post-Processing

Separate elements into layers

Clean up path irregularities

Replace text with editable type

Organize logically for editing

Maps: Special Considerations

Geographic Accuracy

Vector conversion is stylistic, not cartographic

Use for illustrative purposes

For accuracy, use GIS software

Great for simplified location maps

What Works Well

Transit/metro maps (geometric)

Illustrated city maps

Campus/property maps

Trail and route maps

Elements to Rebuild

Labels and place names (use real fonts)

Complex legends

Precise scales

North arrows and symbols

Diagrams: Best Practices

Flowcharts

Ensure high contrast between shapes and lines

Clean backgrounds (remove grid lines if possible)

Text may need manual recreation

Arrows should trace cleanly

Technical Drawings

Line weight matters - use consistent thickness

Remove dimensions before converting (add back as text)

Symbols may need manual cleanup

Hatching patterns may simplify

Organizational Charts

Boxes and connectors trace well

Photos should be replaced

Text needs recreation

Colors can be adjusted easily

Editing Vectorized Maps

Adding Interactivity

SVG maps can be interactive on web

Hover effects for regions

Click to zoom or show info

Animate routes and highlights

Customization

Change color schemes

Add custom markers

Highlight specific areas

Add annotations and callouts

Localization

Replace text for different languages

Adjust layouts for text expansion

Maintain visual consistency

File Organization

Recommended Layers

| Layer | Contents |
|-------|----------|
| Background | Base colors, shapes |
| Paths/Lines | Roads, routes, connectors |
| Shapes | Regions, nodes, boxes |
| Labels | Place names, text |
| Symbols | Icons, markers, arrows |

Common Challenges

Complex Line Work

Problem: Too many paths, slow performance
Solution: Simplify paths, reduce anchor points

Text Conversion

Problem: Text becomes outlines, not editable
Solution: Delete traced text, retype with fonts

Color Banding

Problem: Gradients become stepped
Solution: Recreate gradients in vector software

Missing Detail

Problem: Fine details lost in conversion
Solution: Use higher resolution source, manual touch-up

Output Formats

| Purpose | Format | Notes |
|---------|--------|-------|
| Web | SVG | Interactive capable |
| Print | PDF | Vector preserved |
| Editing | AI/EPS | Full editability |
| Presentations | SVG/PNG | Resolution-appropriate |
