PyOneMap - Python Wrapper for SLA's OneMap API

PyOneMap is a Python package that provides a convenient and easy-to-use interface for interacting with the Singapore Land Authority's (SLA) OneMap API. With PyOneMap, you can retrieve various geospatial data and information from OneMap's services directly from your Python code.

This is built using the API doc release in 2023. The old API documentation and APIs will be available until 31 August 2023.

Features

• Retrieve location details such as addresses, postal codes, and coordinates.
• Search for places of interest, amenities, and landmarks in Singapore.
• Perform geocoding and reverse geocoding operations effortlessly.
• Access map layers and thematic data provided by the OneMap API.

Installation

You can install PyOneMap using pip:

pip install pyonemap

Usage

from pyonemap import OneMap

# Initialize the OneMapAPI client
onemap = OneMap('<--Insert your OneMap API token here-->')

# Get location details
location = onemap.search("5 Havelock Road")
print(location)

geocode = onemap.revGeoCodeXy(24291.97788882387, 31373.0117224489)
print(geocode)

geocode = onemap.revGeoCode(1.3254295, 103.9005321)
print(geocode)

Example

    access_token = os.environ.get("ONEMAP_TOKEN")

    onemap = OneMap(access_token)
    
    location = onemap.search("200640", 'Y', 'Y')
    print(location)

    geocode = onemap.reverseGeocode.revGeoCodeXy(24291.97788882387, 31373.0117224489)

    geocode = onemap.reverseGeocode.revGeoCode(1.3254295, 103.9005321)
    print(geocode)

    route = onemap.routing.route(1.320981, 103.844150, 1.326762, 103.8559)
    print(route['requestParameters']['preferredRoutes'])

Use case: Walk distance between 2 locations

from pyonemap import OneMap

# Obtain access token using email and password.
response = OneMap.getToken('your_email@email.com', 'your_password')
access_token = response['access_token']

# Instantiate OneMap object for API query.
onemap = OneMap(access_token)

# Search for a address using postal code.
start = onemap.search("380016", 'Y', 'Y')
end = onemap.search("658713", 'Y', 'Y')
route = onemap.routing.route(start["results"][0]["LATITUDE"],start["results"][0]["LONGITUDE"],end["results"][0]["LATITUDE"],end["results"][0]["LONGITUDE"], "walk")
route['route_summary']
# {'start_point': '', 'end_point': '', 'total_time': 11662, 'total_distance': 16198}
