# QGIS Style Conversion from Fantasy Map JSON
|
|
|
|
## Overview
|
|
|
|
This document converts the fantasy map styling JSON to QGIS-compatible styles. The original JSON contains SVG/CSS-style properties that need to be translated to QGIS symbology.
|
|
|
|
## Layer Style Conversions
|
|
|
|
### Water Bodies
|
|
|
|
#### Rivers (`#rivers`)
|
|
|
|
```xml
|
|
<!-- QML Style for Rivers -->
|
|
<symbol alpha="1" type="line" name="rivers">
|
|
<layer class="SimpleLine" enabled="1">
|
|
<prop k="color" v="0,137,202,255"/>
|
|
<prop k="width" v="0.8"/>
|

</symbol>
|
|
```
|
|
|
|
### Landmass and Terrain
|
|
|
|
#### Landmass (`#landmass`)
|
|
|
|
```xml
|
|
<!-- QML Style for Landmass -->
|
|
<symbol alpha="1" type="fill" name="landmass">
|
|
<layer class="SimpleFill" enabled="1">
|
|
<prop k="color" v="238,246,251,255"/>
|

|
|
</layer>
|
|
</symbol>
|
|
```
|
|
|
|
#### Ice (`#ice`)
|
|
|
|
```xml
|
|
<!-- QML Style for Ice -->
|
|
<symbol alpha="0.9" type="fill" name="ice">
|
|
<layer class="SimpleFill" enabled="1">
|
|
<prop k="color" v="232,240,246,255"/>
|
|

|
|
<prop k="outline_width" v="1"/>
|
|
</layer>
|
|
</symbol>
|
|
```
|
|
|
|
### Relief and Terrain
|
|
|
|
The Fantasy Map Generator uses SVG icons placed based on elevation to create relief effects. QGIS can replicate this using several approaches:
|
|
|
|
#### Method 1: Hillshade from Elevation Data
|
|
|
|
Create a Digital Elevation Model (DEM) from the cells GeoJSON data:
|
|
|
|
1. **Import cells GeoJSON** with elevation data in the `height` property
|
|
2. **Convert to raster**: Vector → Conversion Tools → Rasterize
|
|
- Use `height` field for raster values
|
|
- Set appropriate resolution (e.g., 100m)
|
|
3. **Generate hillshade**: Raster → Analysis → Hillshade
|
|
- Z factor: 1.0
|
|
- Azimuth: 315° (northwest)
|
|
- Altitude: 45°
|
|
|
|
```xml
|
|
<!-- Hillshade Layer Style -->
|
|
<rasterrenderer opacity="0.6" type="hillshade">
|
|
<rasterproperties>
|
|
<mDrawingStyle>SingleBandGray</mDrawingStyle>
|
|
<mColorShadingAlgorithm>0</mColorShadingAlgorithm>
|
|
<mInvertColor>false</mInvertColor>
|
|
<mGrayBand>1</mGrayBand>
|
|
</rasterproperties>
|
|
</rasterrenderer>
|
|
```
|
|
|
|
#### Method 2: Icon-Based Relief (Fantasy Map Style)
|
|
|
|
Replicate the original icon-based relief using rule-based point symbols:
|
|
|
|
**Step 1**: Create point layer from cell centroids
|
|
- Vector → Geometry Tools → Centroids
|
|
- Filter: `"height" >= 50` (land areas only)
|
|
|
|
**Step 2**: Configure rule-based symbology
|
|
|
|
```xml
|
|
<!-- Mountain Icons (height > 70) -->
|
|
<symbol alpha="1" type="marker" name="mountains">
|
|
<layer class="SvgMarker" enabled="1">
|
|
<prop k="size" v="8"/>
|
|
<prop k="name" v="mountain.svg"/>
|
|
<prop k="color" v="139,69,19,255"/>
|
|
<prop k="angle" v="0"/>
|
|
</layer>
|
|
</symbol>
|
|
|
|
<!-- Hill Icons (height 50-70) -->
|
|
<symbol alpha="1" type="marker" name="hills">
|
|
<layer class="SvgMarker" enabled="1">
|
|
<prop k="size" v="5"/>
|
|
<prop k="name" v="hill.svg"/>
|
|
<prop k="color" v="101,67,33,255"/>
|
|
<prop k="angle" v="0"/>
|
|
</layer>
|
|
</symbol>
|
|
```
|
|
|
|
**Step 3**: Rule expressions
|
|
- Mountains: `"height" > 70`
|
|
- Hills: `"height" >= 50 AND "height" <= 70`
|
|
|
|
#### Method 3: Density-Controlled Relief Points
|
|
|
|
For scattered relief icons (matching FMG's Poisson distribution):
|
|
|
|
**Step 1**: Use Geometry Generator with point symbols
|
|
- Symbol type: Point
|
|
- Geometry type: Point
|
|
- Expression for scattered points:
|
|
|
|
```sql
|
|
-- Generate multiple points per cell based on elevation
|
|
CASE
|
|
WHEN "height" > 70 THEN
|
|
-- Mountains: 2-4 points per cell
|
|
array_to_string(
|
|
array_foreach(
|
|
generate_series(1, floor("height"/30)),
|
|
point_on_surface(
|
|
translate($geometry,
|
|
rand(-50,50),
|
|
rand(-50,50)
|
|
)
|
|
)
|
|
), ','
|
|
)
|
|
WHEN "height" >= 50 THEN
|
|
-- Hills: 1-2 points per cell
|
|
point_on_surface($geometry)
|
|
ELSE
|
|
NULL
|
|
END
|
|
```
|
|
|
|
#### Method 4: Hybrid Approach (Recommended)
|
|
|
|
Combine multiple techniques for best results:
|
|
|
|
1. **Base layer**: Hillshade raster (opacity 30%)
|
|
2. **Mid layer**: Graduated cell polygons by elevation
|
|
3. **Top layer**: Scattered point symbols for major peaks
|
|
|
|
**Graduated Elevation Symbology**:
|
|
```xml
|
|
<!-- Low elevation -->
|
|
<symbol alpha="0.3" type="fill" name="low">
|
|
<layer class="SimpleFill" enabled="1">
|
|
<prop k="color" v="144,238,144,76"/>
|
|
</layer>
|
|
</symbol>
|
|
|
|
<!-- High elevation -->
|
|
<symbol alpha="0.5" type="fill" name="high">
|
|
<layer class="SimpleFill" enabled="1">
|
|
<prop k="color" v="139,69,19,127"/>
|
|
</layer>
|
|
</symbol>
|
|
```
|
|
|
|
#### Relief Color Ramps
|
|
|
|
For elevation-based coloring:
|
|
|
|
**Height Classes**:
|
|
- 0-20: Ocean (blue tones)
|
|
- 20-40: Lowlands (green tones)
|
|
- 40-60: Hills (yellow-brown tones)
|
|
- 60-80: Mountains (brown tones)
|
|
- 80+: High peaks (gray-white tones)
|
|
|
|
```xml
|
|
<!-- Elevation Color Ramp -->
|
|
<colorrampshader colorRampType="INTERPOLATED">
|
|
<item alpha="255" value="0" color="#4A90E2" label="Ocean"/>
|
|
<item alpha="255" value="20" color="#90EE90" label="Coast"/>
|
|
<item alpha="255" value="40" color="#F4A460" label="Hills"/>
|
|
<item alpha="255" value="60" color="#8B4513" label="Mountains"/>
|
|
<item alpha="255" value="80" color="#696969" label="High Peaks"/>
|
|
</colorrampshader>
|
|
```
|
|
|
|
### Political Boundaries

|
Burgs can be styled based on their boolean properties using QGIS rule-based styling. The available burg feature types are:
|
|
|
|
- **capital**: State capitals (administrative centers)
|
|
- **port**: Coastal settlements with harbors
|
|
- **citadel**: Fortified settlements with citadels
|
|
- **walls**: Settlements with defensive walls
|
|
- **plaza**: Settlements with central plazas

|
## Implementation Steps
|
|
|
|
### 1. Create Layer Structure
|
|
|
|
```
|
|
Project Root/
|
|
├── Water Bodies/
|
|
│ ├── Rivers
|
|
│ ├── Lakes
|
|
│ └── Ocean
|
|
├── Landmass/
|
|
│ ├── Base Land
|
|
│ └── Ice
|
|
├── Relief & Terrain/
|
|
│ ├── Elevation DEM (raster)
|
|
│ ├── Hillshade (raster)
|
|
│ ├── Relief Icons (points)
|
|
│ └── Elevation Polygons
|
|
├── Political/
|
|
│ ├── State Borders
|
|
│ └── Province Borders
|
|
├── Transportation/
|
|
│ ├── Routes (by type)
|
|
│ └── Routes (by group)
|
|
└── Settlements/
|
|
├── Burgs (by feature type)
|
|
└── Settlement Labels
|
|
```
|
|
|
|
### 2. Apply Styles in QGIS
|
|
|
|
1. **Load your vector layers** into QGIS
|
|
2. **Right-click layer** → Properties → Symbology
|
|
3. **Copy the XML** from above into a text editor
|
|
4. **Save as .qml file** (e.g., `rivers.qml`)
|
|
5. **Load style** in layer properties → Style → Load Style
|
|
|
|
### 3. Color Reference Table
|
|
|
|
|Original Color|RGB Values|QGIS Color Code|
|
|
|---|---|---|
|
|
|`#000000`|0,0,0|`0,0,0,255`|
|
|
|`#0089ca`|0,137,202|`0,137,202,255`|

## Notes
|
|
|
|
- **Opacity values** from the JSON (like 0.8, 0.9) translate to QGIS alpha values
|
|
- **Stroke-dasharray** properties become custom dash patterns in QGIS
|
|
- **Filter effects** like blur and drop shadows need to be recreated using QGIS effects
|
|
- **Font families** may need substitution if not available in your system
|
|
- **Coordinate system** should be set to the Fantasy Map Cartesian CRS (WKT format below)
|
|
|
|
## Coordinate Reference System (CRS)
|
|
|
|
The Fantasy Map Generator uses a custom Cartesian coordinate system. Use this WKT definition in QGIS:
|
|
|
|
```
|
|
ENGCRS["Fantasy Map Cartesian (meters)",
|
|
EDATUM["Fantasy Map Datum"],
|
|
CS[Cartesian,2],
|
|
AXIS["easting (X)",east,
|
|
ORDER[1],
|
|
LENGTHUNIT["metre",1]],
|
|
AXIS["northing (Y)",north,
|
|
ORDER[2],
|
|
LENGTHUNIT["metre",1]]]
|
|
```
|
|
|
|
### Setting up the CRS in QGIS:
|
|
1. Go to **Settings** → **Custom Projections**
|
|
2. Click **+** to add a new CRS
|
|
3. Set **Name**: `Fantasy Map Cartesian`
|
|
4. Set **Format**: `WKT (Recommended)`
|
|
5. Paste the WKT definition above
|
|
6. Click **OK** and **Apply**
|
|
|
|
## Data Requirements for Relief
|
|
|
|
### Essential GeoJSON Exports
|
|
|
|
To implement relief rendering, you need these exports from Fantasy Map Generator:
|
|
|
|
1. **Cells GeoJSON** (`cells.geojson`)
|
|
- Contains elevation data in `height` property
|
|
- Provides cell polygons for DEM generation
|
|
- Includes biome information for terrain variation
|
|
|
|
2. **Burgs GeoJSON** (`burgs.geojson`)
|
|
- Settlement locations for reference
|
|
- Population data for symbol sizing
|
|
|
|
### Processing Workflow
|
|
|
|
1. **Import cells.geojson** into QGIS
|
|
2. **Create DEM raster**: Vector → Conversion Tools → Rasterize
|
|
- Field: `height`
|
|
- Resolution: 50-200m (depending on map detail)
|
|
- Output extent: Use layer extent
|
|
3. **Generate hillshade**: Raster → Analysis → Hillshade
|
|
4. **Create relief points**: Vector → Geometry Tools → Centroids
|
|
5. **Apply symbology** using the styles below
|
|
|
|
## Rule-Based Styling
|
|
|
|
### Route Styling by Type
|
|
To style routes by their `type` property:
|
|
1. Right-click route layer → Properties → Symbology
|
|
2. Change from "Single Symbol" to "Rule-based"
|
|
3. Add rules with expressions like: `"type" = 'royal'`
|
|
4. Apply the corresponding symbol for each type
|
|
|
|
### Burg Styling by Features
|
|
To style burgs by their feature properties:
|
|
1. Right-click burg layer → Properties → Symbology
|
|
2. Change to "Rule-based" styling
|
|
3. Create rules with expressions like:
|
|
- `"capital" = 1` for capitals
|
|
- `"port" = 1` for ports
|
|
- `"citadel" = 1 OR "walls" = 1` for fortified cities
|
|
4. Set priority order (capitals first, then ports, etc.)
|
|
|
|
### Graduated Symbols by Population
|
|
To size burg symbols by population:
|
|
1. Right-click burg layer → Properties → Symbology
|
|
2. Change to "Graduated"
|
|
3. Set **Value**: `population`
|
|
4. Choose appropriate **Method** and **Classes**
|
|
5. Adjust symbol sizes in the range
|
|
|
|
## Advanced Features
|
|
|
|
For complex effects like the texture overlay (`#texture`) and fogging (`#fogging`), consider:
|
|
|
|
- Using **Raster layers** with blend modes
|
|
- **Layer effects** in symbology
|
|
- **Custom SVG symbols** for complex markers
|
|
- **Expression-based styling** for dynamic effects |
