# GaiaGisService
GaiaGisService is an Angular service that simplifies map creation and interaction using the powerful OpenLayers library. It enables developers to quickly integrate maps, raster layers, and custom points into their applications.
## Features
- **Easy Map Initialization**: Create maps with customizable center, zoom, and design.
- **Raster Layer Management**: Add, remove, and manage raster layers using GeoTIFF files.
- **Point Management**: Add points with custom icons or styles.
- **Flexible View Controls**: Change map center, zoom, or fit to extents dynamically.
## Installation
1. Install the library dependencies:
```bash
npm install ol
```
2. Add the OpenLayers CSS to your application:
```json
// angular.json
"styles": [
"src/styles.css",
]
```
3. Copy the `GaiaGisService` class to your project and ensure the necessary imports are configured.
## Getting Started
### Example Usage
Here is an example of how to use `GaiaGisService` in an Angular application:
#### 1. Add the Service to Your Component
```typescript
import { Component, OnInit } from "@angular/core";
import { GaiaGisService } from "./gaia-gis.service";
@Component({
selector: "app-map",
template: '
',
styles: [".map-container { width: 100%; height: 400px; }"],
})
export class MapComponent implements OnInit {
constructor(private gaiaGisService: GaiaGisService) {}
ngOnInit(): void {
this.gaiaGisService.initializeMap("map", {
center: [-74.006, 40.7128], // New York City
zoom: 12,
});
}
}
```
#### 2. Add Raster Layers
```typescript
addLayer(): void {
this.gaiaGisService.addRasterLayer('https://example.com/map.tif');
}
```
#### 3. Add Points
```typescript
this.gaiaGisService.addPoints(
[
[-74.006, 40.7128],
[-118.2437, 34.0522],
], // NYC & LA
"https://example.com/icon.png"
);
```
