Hi, OSM crew. I'm newbie here. I try to count each POI nodes around specific GPS coordinates. This is my code for loading node around specific lat and lon using Python

overpass_url = "http://overpass-api.de/api/interpreter"
overpass_query = """
out body;
response = requests.get(overpass_url,
                        params={'data': overpass_query})
data = response.json()

From this code, I get every nodes around that specific area. But I have more than 50,000 place to find. I want to know how can I use some variables instead of typing every coordinates in my code.

Moreover, I just want to count every POI node separated by its amenity tag such as 'drinking_water' or 'cafe' but I can't find tag index in data

Thanks for any help.

Your current query is for all nodes, so most of them don't have tags. You probably want to restrict that a bit.

Something like this will only return nodes with an amenity tag or a tourism tag (they don't have to have both):


Generating the query is more a python question, there's lots of ways to do string substitution over there. In Python 3 I tend to use format strings anymore, so you could replace the coordinates in your query with some variables:


Then you'd substitute in the values:


You might also consider using the nwr query operator (along with out center;) instead of node . Then your results will include POIs that are modeled as ways or relations instead of as nodes.
