# Kepler Raster Server
A raster tile server built on top of [TiTiler](https://github.com/developmentseed/titiler) by Development Seed, providing terrain mesh and STAC mosaic capabilities. All TiTiler licenses and attributions apply to this project.
## Features
- **Terrain Mesh Generation**: Generate quantized mesh terrain tiles for 3D visualization for STAC raster tiles and .pmtiles in raster format
- **STAC Mosaic Support**: Dynamic STAC API integration for tile serving
## Installation
### Local Development
1. Clone the repository:
```bash
git clone https://github.com/yourusername/kepler-raster-server.git
cd kepler-raster-server
```
2. Build and run with Docker locally:
```bash
# Enable Docker BuildKit for better caching
export DOCKER_BUILDKIT=1
docker-compose up --build titiler
```
The raster tile server will be available at `http://localhost:8000` and can be used to setup a raster tile layer in kepler.gl during development.
## API Endpoints
The following endpoints are required for raster tile layer in kepler.gl.
### STAC Items
- `/cog/tiles/WebMercatorQuad/{z}/{x}/{y}.npy` - Get stac items in npy format
### STAC Mosaic
- `/stac/mosaic/tiles/{z}/{x}/{y}.npy` - Get mosaic tiles in npy format
### Terrain Mesh
- `/mesh/tiles/{z}/{x}/{y}.terrain` - Get quantized mesh suitable with QuantizedMeshLoader from loaders.gl
## Deployment
### AWS Lambda Deployment
Follow the [TiTiler AWS Lambda deployment guide](https://developmentseed.org/titiler/deployment/aws/lambda/) for serverless deployment. Note that you'll need enough concurrency to support lambda instance per request. In kepler.gl at this moment raster tile layer issues 6 requests per raster server during loading (or 12 when elevation meshes are enabled).
Make sure to setup enough Lambda concurrency, reserved concurency or provisioned concurrency to prevent 503 Service not available message when there are more requests then available simultaneous Lambda instances.
Make sure to control your expenses and don't share your server URL publicly unless intended.
If you need to process many requests concurrently more reliably:
- Use AWS Fargate, ECS, or EC2 where multi-threaded or async server logic is supported
- See the [TiTiler AWS deployment guide](https://developmentseed.org/titiler/deployment/aws/intro/) for more details
### Using in Your Application
To use the server in your Python application:
```python
from kepler_raster_server import app as kepler_app
```
### Publishing to PyPI
To publish a new version to PyPI:
1. Update the version in `pyproject.toml`
2. Run the publish script:
```bash
./scripts/publish.sh
```
