The app supports loading and displaying both SRTM-3 and SRTM-1 tiles.\n\n## Features\n\n- Load and display SRTM-3 and SRTM-1 topographic tiles.\n- Visualize tiles on OpenStreetMap.\n- Display high-resolution height values in the status bar when hovering over a tile.\n- Copy coordinates from Google Maps by pasting (Ctrl+V) into Longitude or Latitude fields.\n- Intuitive and user-friendly interface.\n\n## Installation\n\nTo set up the project locally, follow these steps:\n\n1. Install [Node.js](https://nodejs.org).\n2. Clone the repository:\n   ```bash\n   git clone https://github.com/NeuralCortex/SRTM_Tile_2D_React.git\n   ```\n3. Navigate to the project directory:\n   ```bash\n   cd SRTM_Tile_2D_React\n   ```\n4. Install dependencies:\n   ```bash\n   npm install\n   ```\n5. Start the development server:\n   ```bash\n   npm start\n   ```\n   Or, build for production:\n   ```bash\n   npm run build\n   ```\n\n## Usage\n\n1. Launch the app using `npm start`.\n2. Import an SRTM tile (e.g., `N49E011.hgt`).\n3. View the tile on OpenStreetMap.\n4. Hover over the tile to see height values in the status bar.\n5. Paste coordinates (Ctrl+V) from Google Maps into the Longitude or Latitude fields for precise navigation.\n\n## File Structure\n\nSRTM files typically have names like `N49E011.hgt`.\n\n### Internal Structure\n\nThe `.hgt` file contains 16-bit signed integer values, with no header or trailer.\n\n#### 1x1 Degree SRTM-3 Tile\n```\nNorth X=0,Y=1201 ********************* X=1201,Y=1201\n                 *********************\n                 *********************\n                 *********************\nSouth X=0,Y=0    ********************* X=1201,Y=0\n                 West             East\n```\n\n#### 1x1 Degree SRTM-1 Tile\n```\nNorth X=0,Y=3601 ********************* X=3601,Y=3601\n                 *********************\n                 *********************\n                 *********************\nSouth X=0,Y=0    ********************* X=3601,Y=0\n                 West             East\n```\n\n## Technologies Used\n\n- [Create React App](https://github.com/facebook/create-react-app)\n- [Visual Studio Code](https://code.visualstudio.com/)\n- [Node.js](https://nodejs.org/)\n- [Google Chrome](https://www.google.com/chrome/)\n\n## Getting Started with Create React App\n\nThis project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
