# GRPC elevation service based on gdal data
Relevation expose a GRPC interface to retrieve elevation data from geo points from GDAL tiles.
# TODO
- [ ] LRU in memory cache
- [ ] Authentication
- [ ] HTTP api over grpc
- [ ] Tests
- [ ] Documentation
# Usage
**Under active development**
## Run server
```
relevation run [path to toml config]
```
## Example config
```toml
host = "127.0.0.1"
port = 50051
[[sources]]
id = "some-source-id"
name = "Some Source"
link = "http://link-to-source-data.tld"
attributions = '''
Some authors attributions if needed
'''
resolution = 30
path = "/path/to/root/folder/some-source-folder"
```
## Log level
Set the env variable `RELEVATION_LOG` to `debug`, `info`, `warn`, ...
## Test server
```sh
grpcurl -plaintext -import-path ./proto -proto ./proto/relevation.proto -d '' [::]:50051 relevation.Relevation/Ping
grpcurl -plaintext -import-path ./proto -proto relevation.proto -d '{"point": { "lat": 0, "lng": 0 }}' [::]:50051 relevation.Relevation/GetElevation
# Query for Paris
grpcurl -plaintext -import-path ./proto -proto relevation.proto -d '{"point": { "lat": 48.864716, "lng": 2.349014 }}' [::]:50051 relevation.Relevation/GetElevation
```
## Split geotiff data
