GeoSocialX 0.3.0

Fetch geotagged tweets by geographic radius via the X (Twitter) API v2.

GeoSocialX

GeoSocialX is a Python package designed to make geospatial analysis of tweets easier. Whether you are a social scientist, a data analyst, or just someone curious about the geospatial patterns of tweets, GeoSocialX is for you.

Overview

GeoSocialX bridges social media data and geospatial analysis. It provides a convenient wrapper around the X (Twitter) API v2 (via Tweepy) for fetching geotagged tweets within a geographic area and saving them for further analysis.

Project status: Alpha (0.3.0). The full pipeline — fetch, extract, analyze, visualize — is implemented. Fetching targets the X API v2 recent-search endpoint, which requires a paid X API tier (Basic or higher); the free tier does not include tweet search. The extraction, analysis, and GeoJSON steps are dependency-free; interactive maps use the optional folium extra.

Features

• X API v2 integration: Fetch recent tweets within a geographic area (latitude, longitude, and radius) using the point_radius search operator. The geocode is validated locally, so out-of-range coordinates or an over-cap radius fail fast instead of wasting a paid API call.
• Simple persistence: Save fetched tweets to a newline-delimited JSON file for downstream processing.
• Geospatial extraction: Pull exact (longitude, latitude) points out of v2 tweet dicts, with a coverage report showing how many tweets carried exact coordinates vs. only a place reference. Place-only tweets can optionally be resolved to their place's bounding-box centroid, and every point records its source ("exact" or "place").
• Geospatial analysis: Bounding box, centroid, great-circle (haversine) distances, radius filtering, and a lightweight grid-based hotspot finder — all pure standard library.
• Visualization: Export points to GeoJSON (standard library) or render an interactive Leaflet map with markers and a density heatmap (optional folium extra).

Geo coverage caveat: point_radius only matches tweets that carry geo data, and the radius is capped at 25 mi / 40 km. Only a small fraction of tweets are geotagged with exact coordinates, so results are far sparser than a naïve keyword search — resolving place_id references (see below) recovers a coarser but much larger share.

Requirements

• Python 3.10 or higher
• An X Developer account on a paid tier (Basic or higher) — recent search is not available on the free tier
• An X API bearer token (app-only auth is sufficient for recent search)

Dependencies

Declared in pyproject.toml:

• tweepy >=4.10 — X API v2 client

Optional extras:

• example — python-dotenv, to load credentials from a .env file (pip install "geosocialx[example]").
• maps — folium, to render interactive Leaflet maps (pip install "geosocialx[maps]"). Not needed for GeoJSON export.
• test — coverage, for running the suite with coverage measurement (pip install "geosocialx[test]").

Installation

From PyPI

GeoSocialX is published on PyPI under the distribution name geosocialx (the import name is geosocialx too):

pip install geosocialx

With optional extras (comma-separated):

pip install "geosocialx[example,maps,test]"

From source

git clone https://github.com/JayeshSuryavanshi/GeoSocialX.git
cd GeoSocialX
pip install .           # or:  pip install ".[example,maps,test]"

Configuration

GeoSocialX needs an X API bearer token, read from the TWITTER_BEARER_TOKEN environment variable (loaded from a .env file when the example extra is installed):

TWITTER_BEARER_TOKEN=your_bearer_token

Note: .env is git-ignored. Never commit real credentials.

TwitterDataFetcher can also authenticate in user context with the four OAuth 1.0a credentials (api_key, api_key_secret, access_token, access_token_secret) passed as keyword arguments, but app-only bearer-token auth is the simplest path for recent search.

Usage

Command line

Installing the package registers a geosocialx console command:

geosocialx --geocode "37.7749,-122.4194,10mi" --count 100 --output tweets.json

This writes the fetched tweets to tweets.json (one JSON object per line) and, when any tweets reference a place, the collected place bounding boxes to tweets.json.places.json. The same entry point is available as python main.py (run either with --help for all options).

Programmatic

from geosocialx import TwitterDataFetcher

fetcher = TwitterDataFetcher(bearer_token="your_bearer_token")

# Fetch up to 100 tweets within 10 miles of San Francisco.
tweets = fetcher.fetch_tweets("37.7749,-122.4194,10mi", count=100)
if tweets is not None:  # None means the API/network call failed
    fetcher.save_tweets_to_file(tweets, "tweets.json")
    fetcher.save_places_to_file("tweets.json.places.json")  # place bboxes, if any

fetch_tweets returns None (and logs the error) if the call fails, so guard with if tweets is not None. save_tweets_to_file raises ValueError if handed None, so it never truncates an existing file on a failed fetch.

Analyze and visualize saved tweets

Once you have a tweets.json (from the step above, or any newline-delimited v2 tweet dump), the rest of the pipeline is offline and needs no API access:

from geosocialx import GeospatialExtractor, GeospatialAnalyzer, MapVisualizer

extractor = GeospatialExtractor()
tweets = extractor.load_tweets("tweets.json")
print(extractor.coverage(tweets))  # e.g. {'total': 100, 'with_point': 12, ...}

# Pass a {place_id: bbox} map (from save_places_to_file) to also resolve
# place-only tweets to their bounding-box centroid; omit it for exact points only.
places = extractor.load_places("tweets.json.places.json")
points = extractor.extract_points(tweets, places=places)

analyzer = GeospatialAnalyzer(points)
print(analyzer.summary())  # count, bounding_box, centroid, span_km
print(analyzer.densest_cells(top=3))  # busiest grid cells

viz = MapVisualizer(points)
viz.save_geojson("tweets.geojson")  # standard library, always available
viz.to_html_map("tweets_map.html")  # interactive map — needs the `maps` extra

A complete, offline version of this that needs no API access or paid tier is in examples/analyze.py; it runs against a committed sample dump:

python examples/analyze.py

Key Modules & Functions

geosocialx.data_fetcher

TwitterDataFetcher(bearer_token=None, *, api_key=None, api_key_secret=None, access_token=None, access_token_secret=None, wait_on_rate_limit=True)

Builds a Tweepy v2 Client. Pass a bearer_token for app-only auth, or all four OAuth 1.0a credentials as keyword arguments for user-context auth. Raises ValueError if neither is provided. By default it waits out rate limits (429s); pass wait_on_rate_limit=False to fail fast instead.

• fetch_tweets(geocode, count=100, extra_query="-is:retweet", tweet_fields=(...), start_time=None, end_time=None) — Returns a list of tweet dicts within the given area, or None (logging the error) if the API call or network transport fails. geocode is "latitude,longitude,radius" (e.g. "37.7749,-122.4194,10mi", radius ≤ 25mi/40km), validated locally and translated to the v2 point_radius:[longitude latitude radius] operator (note: v2 puts longitude first). start_time/end_time (datetime) optionally narrow the search inside the ~7-day recent-search window. The place bounding boxes referenced by the results are collected into the places attribute.
• save_tweets_to_file(tweets, file_name) — Writes each tweet dict as newline-delimited JSON. Raises ValueError on None rather than truncating the destination.
• save_places_to_file(file_name) — Writes the collected {place_id: bbox} map as JSON.

geosocialx.geospatial_extractor

GeospatialExtractor turns raw v2 tweet dicts into geographic points.

• extract_points(tweets, places=None) — Returns a list of GeoPoint(tweet_id, longitude, latitude, text, created_at, author_id, source) for every tweet with a usable location. Tweets with exact coordinates yield source="exact"; if a places map is given, place-only tweets are additionally resolved to their bounding-box centroid as source="place". Malformed or out-of-range coordinates are skipped.
• coverage(tweets) — Returns {total, with_point, place_only, no_geo} so you can see how sparse the geo data is (with_point counts exactly what extract_points keeps as exact points).
• load_tweets(path) / load_places(path) — Load the newline-delimited tweets / {place_id: bbox} map written by the fetcher.

geosocialx.geospatial_analyzer

GeospatialAnalyzer(points) computes spatial statistics with no third-party dependencies.

• count(), bounding_box() → (min_lon, min_lat, max_lon, max_lat), centroid() → (lon, lat).
• haversine_km(lon1, lat1, lon2, lat2) — great-circle distance in km (static).
• points_within(lon, lat, radius_km) — points inside a radius.
• densest_cells(cell_size_deg=0.01, top=5) — busiest grid cells. Cells are equal in degrees, not equal in area (~1.1 km tall but ~1.1·cos(lat) km wide at 0.01°), so it is a within-city hotspot heuristic, not a cross-latitude density estimate.
• time_bins(freq="day"|"hour") — bucket points by their created_at timestamp as {bucket: count} (ordered by bucket), skipping any point without a parseable timestamp.
• summary() — count, bounding_box, centroid, bbox diagonal span_km, and earliest/latest (UTC ISO-8601) when the points carry timestamps.

geosocialx.data_visualization

MapVisualizer(points) renders points to disk.

• to_geojson() / save_geojson(path) — a GeoJSON FeatureCollection (standard library only; each feature carries the point's source).
• to_html_map(path, zoom_start=12, heatmap=True) — an interactive Leaflet map with markers and an optional heatmap layer. Requires the maps extra (folium); raises ImportError with an install hint if it is missing.

Running the tests

The test suite is network-free (Tweepy is mocked):

python -m unittest discover -s tests

With coverage (install the test extra first) and the folium-backed map tests exercised (install the maps extra):

pip install ".[maps,test]"
coverage run -m unittest discover -s tests
coverage report
