# Dataset Overview

Before conducting data processing, have a look at the synthetic dataset.

## We prepare a dataset, as shown below

```{python}
import pandas as pd
df = pd.read_csv('location.csv', sep='\t', index_col=0)
df
```
- location_name: the parking plot location
- latitude: latitude of the parking plot
- longtitude: longtitude of the parking plot
- price/hour: price to be charged per hour
- is_outdoor: is the parking plot outdoor or inside 
- ego_pay: does the parking plot support "EgoPay"

## Get current location, update location through API
```{python}
import requests
class EgoCar:
    
    def __init__(self, api_url):
        self.api_url = api_url
        self.api_key = '7443363c-4304-4c56-9df0-6af4af40c613'
        self.header = {'Content-type': 'application/json', 'X-Api-Key': self.api_key}
        
    def get_location(self):
        res = requests.get(self.api_url, headers=self.header)
        location = res.json()['location']
        return location
    
    def update_location(self, new_location):
        x, y = new_location.split(',')
        x, y = float(x), float(y)
        if x >= -90 and x <= 90 and y >= -90 and y <= 90:
            data = {'location': new_location}
            requests.patch(self.api_url, json=data, headers=self.header)
            print('new location: ', new_location)
        else:
            print('[Error] Latitude value must be between -90 and 90')
```

- get current location
```{python}
api_url = 'https://ego-vehicle-api.azurewebsites.net/api/v1/vehicle/signals'
ego_car = EgoCar(api_url)
print('current location: ', ego_car.get_location())
```
- update location

```{python}
ego_car.update_location('51.00, 6.00')
```
