# Geo Indexer
Geo Indexer traverse and index points along a route.
Services that are part of Geo Indexer:
- `RouteGuide`
- `GetFeature`: Obtains the feature at a given position.
- `ListFeatures`: Obtains the features available within the given region(rectangle).
- `RecordRoute`: Accepts a stream of points on a route being traversed.
- `RouteChat`: Accepts a stream of `RouteNote`s sent while a route is being
traversed. A `RouteNote` is a message sent while at a given point.
## Usage
Execute the following commands from the project root directory:
1. Run the server:
```sh
$ go run server/server.go
```
2. From another terminal, run the client:
```sh
$ go run client/client.go
```
You’ll see output like this:
```sh
