# SRTM Tile 2D Viewer React 1.0.0
The SRTM Tile 2D Viewer is a web application built with React that enables users to visualize topographic data from NASA's [Shuttle Radar Topography Mission (SRTM)](https://en.wikipedia.org/wiki/STS-99) on OpenStreetMap. The app supports loading and displaying both SRTM-3 and SRTM-1 tiles.
## Features
- Load and display SRTM-3 and SRTM-1 topographic tiles.
- Visualize tiles on OpenStreetMap.
- Display high-resolution height values in the status bar when hovering over a tile.
- Copy coordinates from Google Maps by pasting (Ctrl+V) into Longitude or Latitude fields.
- Intuitive and user-friendly interface.
## Installation
To set up the project locally, follow these steps:
1. Install [Node.js](https://nodejs.org).
2. Clone the repository:
```bash
git clone https://github.com/NeuralCortex/SRTM_Tile_2D_React.git
```
3. Navigate to the project directory:
```bash
cd SRTM_Tile_2D_React
```
4. Install dependencies:
```bash
npm install
```
5. Start the development server:
```bash
npm start
```
Or, build for production:
```bash
npm run build
```
## Usage
1. Launch the app using `npm start`.
2. Import an SRTM tile (e.g., `N49E011.hgt`).
3. View the tile on OpenStreetMap.
4. Hover over the tile to see height values in the status bar.
5. Paste coordinates (Ctrl+V) from Google Maps into the Longitude or Latitude fields for precise navigation.
## File Structure
SRTM files typically have names like `N49E011.hgt`.
### Internal Structure
The `.hgt` file contains 16-bit signed integer values, with no header or trailer.
