# GeoComp

## Dataset description

Inspired by [geoguessr.com](https://www.geoguessr.com/), we developed a free geolocation game platform that tracks participants' competition histories.
Unlike most geolocation websites, including Geoguessr, which rely solely on samples from Google Street View, our platform integrates Baidu Maps and Gaode Maps to address coverage gaps in regions like mainland China, ensuring broader global accessibility.
The platform offers various engaging competition modes to enhance user experience, such as team contests and solo matches.
Each competition consists of multiple questions, and teams are assigned a "vitality score". Users mark their predicted location on the map, and the evaluation is based on the ground truth's surface distance from the predicted location. 
Larger errors result in greater deductions from the team's vitality score. 
At the end of the match, the team with the higher vitality score wins.
We also provide diverse game modes, including street views, natural landscapes, and iconic landmarks.
Users can choose specific opponents or engage in random matches.
To prevent cheating, external search engines are banned, and each round is time-limited.
To ensure predictions are human-generated rather than machine-generated, users must register with a phone number, enabling tracking of individual activities. 
Using this platform, we collected **GeoComp**, a comprehensive dataset covering 1,000 days of user competition.

## File Introduction

The GeoComp dataset is now primarily provided in Parquet format within the `/data` directory for efficient access and processing. You can find the following files in this repository:

* [**`/data/tuxun_combined.parquet`**](https://huggingface.co/datasets/ShirohAO/tuxun/tree/main/data): This is the main dataset file containing combined competition history in Parquet format.
* [**`tuxun_sample.csv`**](https://huggingface.co/datasets/ShirohAO/tuxun/blob/main/tuxun_sample.csv): An example CSV file to preview the structure of the data.
* [**`selected_panoids`**](https://huggingface.co/datasets/ShirohAO/tuxun/blob/main/selected_panoids): The 500 panoids we used in our work. You can add a `.csv` or `.json` suffix to this file.
* [**`download_panoramas.py`**](https://huggingface.co/datasets/ShirohAO/tuxun/blob/main/download_panoramas.py): A script to download street view images using the provided panoids.

## Requirement

The **GeoComp** is only for research.

## Start

### Data format of tuxun_combined.csv

The `tuxun_combined.parquet` file contains data in a same structure to the original `tuxun_combined.csv`.

**Example Schema:**

| id   | data                | gmt_create      | timestamp |
| ---- | ------------------- | --------------- | --------- |
| Game | Json style metadata | 1734188074762.0 |           |

**Explanation:**

* We hide data items that may reveal personal privacy like changing the value of key "userId" to "User", "hostUserId" to "HostUser", "playerIds" to "Players", "id" to "Game".
* The data under the "data" column is in JSON style. This column contains detailed geolocation information like "lat", "lng", "nation", and "panoId".

### Extracting Specific Fields from the 'data' Column

The 'data' column contains rich game-specific information in a JSON string format. To access individual fields like `guessPlace`, `targetPlace`, `score`, or `panoId`, you'll need to parse this JSON string.

Here’s a Python example using `pandas` and `json` to extract these fields from the `tuxun_combined.parquet` file:

```python
import pandas as pd
import json

# Assuming your Parquet file is at 'data/tuxun_combined.parquet'
# Adjust the file_path if necessary
file_path = 'data/tuxun_combined.parquet'

# Read the Parquet file into a DataFrame
df = pd.read_parquet(file_path)

# Define a function to parse the 'data' column and extract desired information
def extract_game_details(data_json_str):
    try:
        # Parse the JSON string into a Python dictionary
        game_data = json.loads(data_json_str)

        # Initialize variables to None in case a field is missing
        guess_place = None
        target_place = None
        score = None
        pano_id = None

        # Extract guessPlace, targetPlace, and score from 'player' -> 'lastRoundResult'
        if 'player' in game_data and 'lastRoundResult' in game_data['player']:
            last_round_result = game_data['player']['lastRoundResult']
            guess_place = last_round_result.get('guessPlace')
            target_place = last_round_result.get('targetPlace')
            score = last_round_result.get('score')

        # Extract panoId from the first element of the 'rounds' list
        if 'rounds' in game_data and len(game_data['rounds']) > 0:
            first_round = game_data['rounds'][0]
            pano_id = first_round.get('panoId')

        return guess_place, target_place, score, pano_id
    except json.JSONDecodeError:
        print(f"Error decoding JSON for row: {data_json_str[:100]}...") # Print first 100 chars for context
        return None, None, None, None
    except KeyError as e:
        print(f"Missing key: {e} in row: {data_json_str[:100]}...") # Print first 100 chars for context
        return None, None, None, None

# Apply the function to the 'data' column and create new columns in the DataFrame
df[['guessPlace', 'targetPlace', 'score', 'panoId']] = df['data'].apply(
    lambda x: pd.Series(extract_game_details(x))
)

# Display the first few rows with the newly extracted columns
print(df[['id', 'guessPlace', 'targetPlace', 'score', 'panoId']].head())
```
