# Main Settings

Main Settings define the core parameters for map generation including game version, coordinates, map size, rotation, and other fundamental properties that control the overall map structure.

🆕 **Presets Available**: With [Local Deployment](/docs/setup-and-installation/local_deployment.md), you can save and manage multiple Main Settings configurations using the [Presets](/docs/additional-features/presets.md) system. Store different coordinate sets, map sizes, and game versions for quick access.

## Map Dimensions

### Standard Sizes

Choose from professionally optimized map sizes. Larger maps require [Local deployment](/docs/setup-and-installation/local_deployment.md) for sufficient processing power.

**Available Sizes:**

* **2×2 km** - Perfect for detailed farming operations
* **4×4 km** - Balanced size for diverse gameplay
* **8×8 km** - Expansive agricultural landscapes
* **16×16 km** - Maximum scale (⚠️ **Compatibility Warning**: May exceed engine limitations, causing Giants Editor crashes)

## Game Platform Selection

Choose your target Farming Simulator version from the dropdown menu. Default: **Farming Simulator 25**.

## Geographic Coordinates

**Latitude and Longitude**: Define the exact center point of your map using decimal coordinates (e.g., `45.28, 20.23`).

**Critical Requirement**: Use decimal format only. Other coordinate formats will cause generation failure.

### Map Size

#### Default sizes

The tool supports all possible sizes of maps, but some of them only available in the [Local deployment](/docs/setup-and-installation/local_deployment.md).\
The sizes are:

* 2x2 km
* 4x4 km
* 8x8 km
* 16x16 km

**NOTE:** 16 km maps may not work reliably due to game engine limitations. The map can be generated, but you may have issues opening it in Giants Editor.

### Advanced: Custom Dimensions

**Expert Feature**: Specify non-standard map sizes for specialized requirements.

**⚠️ CRITICAL LIMITATION**: Giants Editor **only supports** square maps with power-of-2 dimensions (2048m, 4096m, 8192m). Custom sizes will generate successfully but **will crash Giants Editor** during import.

**Recommended Use**: Research and testing purposes only.

### Scaling Configuration

**Output Size**: Apply intelligent scaling to fit larger real-world regions into compatible map dimensions.

**Example Use Case**: Capture a 3000m×3000m real-world area but output as a 2048m×2048m Giants Editor-compatible map. The terrain detail and geographic accuracy are preserved while ensuring editor compatibility.

**Strategic Advantage**: Access larger geographic regions without sacrificing Giants Editor stability.

## Elevation Data Sources

**DTM Provider**: Select your Digital Terrain Model data source for accurate elevation mapping.

**Default Provider**: `SRTM30Provider` - Global coverage with moderate resolution, reliable worldwide availability.

**Optimization Strategy**: Choose the **highest resolution provider available** for your region. The interface automatically filters providers based on your coordinates, showing only compatible options.

**Quality Hierarchy**: Regional providers typically offer superior resolution compared to global datasets. Prioritize local data sources when available.

**⚠️ Community Providers**: Third-party providers are experimental and unsupported. Use at your own risk - contact provider authors directly for technical issues.

## Orientation Control

**Map Rotation**: Apply precise angular adjustments to optimize map orientation for gameplay or geographic accuracy.

**Range**: 0° to 360° (decimal values accepted) **Default**: 0° (North-aligned) **Application**: Affects both terrain elevation and all geographic features uniformly

**Strategic Uses**:

* Align field boundaries with preferred farming patterns
* Optimize road networks for logical traffic flow
* Match real-world cardinal directions for immersive gameplay
