abs-geolocation-core

Overview

The abs-geolocation-core package provides a set of utilities powered by Azure Maps for geolocation services. It includes features such as geocoding, reverse geocoding, distance calculations, routing, elevation data, weather information, and traffic data.

Features

• Geocode Address: Get location by address.
• Reverse Geocode: Get address by latitude/longitude.
• Distance Between: Calculate Haversine distance in meters or by road via route.
• Get Route: Determine the route between two or more locations.
• Elevation Along: Retrieve elevation for points or lines.
• Weather At: Get current weather at a location.
• Traffic At: Get traffic flow and relative congestion at a location.
• Nearest By Distance: Find nearest candidates to an origin by straight-line distance.
• Nearest By Drive Distance: Find nearest by driving distance using Route Matrix.
• Nearest By Drive Time: Find nearest by driving time using Route Matrix.
• Nearest Ranked: Rank candidates by time and distance.
• Nearest Ranked With Weather: Rank candidates by time, distance, and weather conditions.
• Nearest Ranked With Weather and Traffic: Rank candidates by time, distance, weather, and traffic conditions.

Installation

To install the package, use the following command:

pip install abs-geolocation-core

Usage

Here is a basic example of how to use the abs-geolocation-core package:

import asyncio
from abs_geolocation_core.location_service import AzureMapsAuth, LocationService

async def main():
    auth = AzureMapsAuth(subscription_key="<YOUR_KEY>")  # or sas_token_provider=lambda: "sv=...&sig=..."
    svc = LocationService(auth)
    places = await svc.geocode_address("Mumbai Central, Mumbai")
    print(places[0]["position"])  # lat/lon from geocode result
    origin = (19.0760, 72.8777)  # Mumbai
    dest = (18.5204, 73.8567)    # Pune
    route = await svc.get_route([origin, dest])
    print(route["routes"][0]["summary"])
    best = await svc.nearest_by_drive_time(origin, [(18.5204, 73.8567), (21.1458, 79.0882)])
    print(best)
    await svc.aclose()

if __name__ == "__main__":
    asyncio.run(main())

API Mapping to Azure Maps

The service maps to the following Azure Maps REST endpoints (host: https://atlas.microsoft.com):

• Search: GET /search/address/json, GET /search/address/reverse/json, GET /search/fuzzy/json (api-version: 1.0 configurable)
• Route: GET /route/directions/json (api-version: configurable), POST /route/matrix/sync/json (matrix api-version: configurable)
• Elevation: GET /elevation/point/json, GET /elevation/line/json (api-version: 1.0 configurable)
• Weather: GET /weather/currentConditions/json (api-version: 1.1 configurable)
• Traffic: GET /traffic/flowSegment/relative/json (api-version: 1.0 configurable)

Refer to Azure Maps REST docs for details on parameters and responses:

• Search: [Azure Maps Search REST]
• Route: [Azure Maps Route REST]
• Matrix: [Azure Maps Route Matrix REST]
• Elevation: [Azure Maps Elevation REST]
• Weather: [Azure Maps Weather REST]
• Traffic: [Azure Maps Traffic REST]

Configuration

You can override API versions and timeouts via the LocationService constructor:

svc = LocationService(
    AzureMapsAuth(subscription_key="<KEY>"),
    api_version_search="1.0",
    api_version_route="1.0",
    api_version_matrix="2.0",
    api_version_elevation="1.0",
    api_version_weather="1.1",
    api_version_traffic="1.0",
    timeout=10.0,
)

For SAS authentication:

svc = LocationService(
    AzureMapsAuth(sas_token_provider=lambda: "<SAS_TOKEN>"),
)

Requirements

• Python 3.11 or higher
• Azure Maps services enabled for your resource (Search, Routing, Elevation, Weather, Traffic)
