OpenStreetMap Location Features is a Python library that utilizes the OpenStreetMap (OSM) database and Overpass API to retrieve location features and perform various calculations based on the given location. It allows you to extract information about amenities, landuse, leisure, tourism, natural features, highways, railways, and waterways for a specified location.

The following are keys provided by OpenStreetMap (OSM). Each link is a reference to the official OSM Wiki.

Amenities: https://wiki.openstreetmap.org/wiki/Key:amenity
Landuse : https://wiki.openstreetmap.org/wiki/Key:landuse
Leisure : https://wiki.openstreetmap.org/wiki/Key:leisure
Tourism : https://wiki.openstreetmap.org/wiki/Key:tourism
Natural : https://wiki.openstreetmap.org/wiki/Key:natural
Highway : https://wiki.openstreetmap.org/wiki/Key:highway
Railway : https://wiki.openstreetmap.org/wiki/Key:railway
Waterway : https://wiki.openstreetmap.org/wiki/Key:waterway

Important Note:

The images included in this README file are taken from the Overpass API. While these images represent the responses of queries used in this module, it should be noted that this module does not return any visual content; it only provides the corresponding response data.

Installation

pip install osmlf

Usage

Here's examples

# Import the osmlf module
>>> from osmlf import osmlf

For example let's look New York City, USA. osmlf will find best result from given location automatically

>>> lf = osmlf('New York City, USA')
>>> lf
osmlf(City of New York, New York, United States)

Default Values

Here are the default values for each key. These are the values that are checked when the key parameter in the relational method's parameter is left blank by the user. You can access and modify these default values if needed:

>>> lf.default_values
{
    'amenity': [
        'bar', 'cafe', 'fast_food', 'food_court', 'pub', 'restaurant',
        'college', 'library', 'school', 'university', 'atm', 'bank',
        'clinic', 'dentist', 'doctors', 'hospital', 'pharmacy', 'veterinary',
        'cinema', 'conference_centre', 'theatre', 'courthouse', 'fire_station',
        'police', 'post_office', 'townhall', 'marketplace', 'grave_yard'
    ],
    'landuse': ['forest', 'residential', 'commercial', 'industrial', 'farming'],
    'leisure': ['marina', 'garden', 'park', 'playground', 'stadium'],
    'tourism': [
        'aquarium', 'artwork', 'attraction', 'hostel', 'hotel', 
        'motel', 'museum', 'theme_park', 'viewpoint', 'zoo'
    ],
    'natural': ['beach'],
    'highway': [
        
    ],
    'railway': ['platform', 'station', 'stop_area'],
    'waterway': []
}

Administrative

Retrieves and returns administrative information about the location from the Overpass API.

Note: The total_area variable is expressed in square kilometers.

>>> admin = lf.administrative()
>>> admin
{
    'core': (40.7127281, -74.0060152),
    'subareas': {
        'total_subareas': 5,
        'subarea_relation_ids': [
            8398124,
            9691750,
            9691819,
            9691916,
            9691948
        ]
    },
    'total_area': 1147.9149733707309
}

Amenity

Let's examine the amenities in the Financial District, Manhattan:

>>> lf = osmlf('Financial District, Manhattan, New York')
>>> lf
osmlf(Financial District, Manhattan, New York County, City of New York, New York, United States)

# Search with default amenity values
>>> amenity = lf.amenity()
>>> amenity.keys()
dict_keys(['nodes', 'ways'])

Nodes represent locations with a single latitude and longitude pair. Most often, nodes represent smaller areas, such as banks, cafes, bars, restaurants, etc.

Ways, on the other hand, represent areas with multiple latitude and longitude pairs. They usually represent relatively large areas like hospitals, schools, government buildings, etc.

>>> amenity['nodes'].keys()
dict_keys(['bar', 'cafe', 'fast_food', 'food_court', 'pub', 'restaurant', 'college', 'library', 'school', 'university', 'atm', 'bank', 'clinic', 'dentist', 'doctors', 'hospital', 'pharmacy', 'veterinary', 'cinema', 'conference_centre', 'theatre', 'courthouse', 'fire_station', 'police', 'post_office', 'townhall', 'marketplace', 'grave_yard'])

For example, let's examine the bars in the Financial District. To do this, we must check both nodes and ways keys:

# Number of bars in Financial District
>>> len(amenity['nodes']['bar'])
11

# Lets check first bar in that list
>>> amenity['nodes']['bar'][0]
{
    'id': 3450976122,
    'tags': {'addr:city': 'New York',
        'addr:housenumber': '36',
        'addr:postcode': '10004',
        'addr:state': 'NY',
        'addr:street': 'Water Street',
        'alt_name': 'Porterhouse Bar',
        'amenity': 'bar',
        'name': 'The Porterhouse Brew Co',
        'opening_hours': 'Mo-Fr 11:00-22:00',
        'outdoor_seating': 'yes',
        'website': 'http://www.zigolinis.com',
        'wheelchair': 'no'},
    'coordinate': (40.703439, -74.0106749)
}

In this example, we retrieve all the information available from the Overpass API. There are 11 bars in the Financial District represented as nodes. Let's check if there are any bars represented as way objects:

>>> amenity['ways']['bar']
{'ways': [], 'way_count': 0, 'total_area': 0}   # Empty result

Now, let's examine the hospitals in the Financial District.

Unfortunately, we can't see the number of way objects using the len function. The number of ways is returned in the way_count key in the dictionary.

Note: This is a known issue that will be fixed in the future.

# Number of hospitals as nodes
>>> len(amenity['nodes']['hospital'])
0

# Number of hospitals as ways
>>> amenity['ways']['hospital']['way_count']
1

# Get all the hospitals
>>> amenity['ways']['hospital']
{
    'ways': [
        {
            'way_id': 799488173,
            'tags': {'amenity': 'hospital',
                'beds': '132',
                'building': 'yes',
                'healthcare': 'hospital',
                'name': 'NewYork-Presbyterian Lower Manhattan Hospital',
                'wikidata': 'Q7013458'
            },
            'coordinates': [
                (40.7108086, -74.0050874),
                (40.7102038, -74.0044209),
                (40.7101336, -74.0045362),
                (40.7101256, -74.0045289),
                (40.7101041, -74.0045094),
                (40.7098032, -74.0048554),
                (40.7103763, -74.0054502),
                (40.7104325, -74.0055085),
                (40.7104501, -74.0054787),
                (40.7106556, -74.0051304),
                (40.7107336, -74.0052148),
                (40.7108086, -74.0050874)
            ],
           'area': 0.004740726486962053
        }
    ],
 'way_count': 1,
 'total_area': 0.004740726486962053
}

In this example, amenity information is fetched using default keys, but you could also specify the keys like so:

# Get bars only
>>> bars = lf.amenity('bar')

# Get hospitals only
>>> hospitals = lf.amenity('hospital')

# Get bars and hospitals both at the same time
>>> multiple_amenities = lf.amenity(['bar', 'hospital']) # TODO: Use *args

Note: The amenity function works the same way with the landuse, leisure, tourism, natural, railway, and waterway functions. The only difference is the highway function.

Landuse

Retrieves landuse information about the location from the Overpass API

# Amsterdam
>>> lf = osmlf('Amsterdam, Netherlands')
>>> lf
osmlf(Amsterdam, Noord-Holland, Nederland)

# Get general info (administrative) of Amsterdam
>>> admin = lf.administrative()
>>> admin
{
    'core': (52.3730796, 4.8924534), 
    'subareas': {
        'total_subareas': 0, 
        'subarea_relation_ids': []
    }, 
    'total_area': 184.6089486197638
}

When examining a relatively large area like Amsterdam, the landuse function can return a large amount of data, which can sometimes be challenging to process. To manage this, let's first fetch only the residential landuses instead of using the default keys, which would fetch all landuses at once.

# Residential areas of Amsterdam
>>> residential = lf.landuse('residential')

>>> residential.keys()
dict_keys(['nodes', 'ways'])

# No nodes for residential
>>> residential['nodes']
{'residential': []}

# Number of residential areas
>>> residential['ways']['residential']['way_count']
192

# Total area of residential areas in square kilometers
>>> residential['ways']['residential']['total_area']
57.0395957478018

To retrieve the first residential area among the 192 areas:

# Get first residential area
>>> residential['ways']['residential']['ways'][0]
{
    'way_id': 6337974, 
    'tags': {
        'landuse': 'residential'
    }, 
    'coordinates': [
        (52.3873421, 4.7586896), (52.3873206, 4.7586027), (52.3872219, 4.7584746),

In this example, we're only showing residential areas, but landuse can fetch more than just residential areas—it can also fetch forests, commercial areas, industrial areas, farming areas, etc.

For example:

# Get total area of forest, meadow and grass in Amsterdam
# It will take some time
>>> landuse = lf.landuse(['forest', 'meadow', 'grass'])

# Show keys
>>> landuse['ways'].keys()
dict_keys(['forest', 'meadow', 'grass'])

# Forest area in square kilometers
>>> landuse['ways']['forest']['total_area']
9.608440158531183

# Meadow area in square kilometers
>>> landuse['ways']['meadow']['total_area']
10.776521682770907

# Grass area in square kilometers
>>> landuse['ways']['grass']['total_area']
31.5818360868127

Tourism

Retrieves tourism information about the location from the Overpass API.

>>> lf = osmlf('Venice, Italy')
>>> lf
osmlf(Venezia, Veneto, Italia)

>>> tourism = lf.tourism()

Natural

This function retrieves natural feature information about the location from the Overpass API. The default value for the natural key is beach.

>>> lf = osmlf('Fethiye, Mugla, Turkey')

Highway

Highways function a bit differently compared to other functions. For instance, unlike the tourism function where we can search for the hotel key, in the highway function we can't find tags by keys because it only lists the items.

>>> lf = osmlf('sodermalm, stockholm, sweden')
>>> lf
osmlf(Södermalm, Södermalms stadsdelsområde, Stockholm, Stockholms kommun, Stockholms län, Sverige)

The total_length key provides the total length of every road listed in info in kilometers.

# Get highway information
>>> highway = lf.highway()

>>> highway.keys()
dict_keys(['total_length', 'info'])

total_lenght is total length of every road in info in kilometers

# Get total length of all roads returned in kilometers
>>> highway['total_length']
279.45176280917764

In the info list, we have details about every road. We can filter by type, such as motorways, pedestrian, residential roads, etc.

# Get residential roads
>>> residential = lf.highway('residential')

# Total length of residential
>>> residential['total_length']
58.977220710878655

# Get first residential road in list
>>> residential['info'][0]

Railway

Retrieves railway information about the location from the Overpass API.

>>> lf = osmlf('Moscow, Russia')
>>> lf
osmlf(Москва, Центральный федеральный округ, Россия)

>>> railway = lf.railway()


>>> railway.keys()
dict_keys(['nodes', 'ways'])

# Number of stations

# Get first station
>>> railway['nodes']['station'][0]
