Overpass-API | A database engine to query the OpenStreetMap data | Map library

I set the return to null for the component and condition in question to check the data I'm returning and I couldn't find any issues in the coordinates arrays.

I get data as an array of geometry collections containing linestrings that make borders (from OSM's Overpass). Leaflet seems to only accept shapes, features, and featurecollections as inputs. As such, I wrote something to convert each geometry collection to a feature containing a multipolygon and added in a name and ID properties then made it into a featurecollection.

Example of OSM request body

I am trying to document a Python class that has some class-level member variables, but I could not get it appropriately documented using reST/Sphinx.

The code is this:

I'm using the helper function provided here with some modifications for distance and color. I tried it without my changes and it has the same result. I noticed if I used the 'natural' tag that water ways will extend past the figure but I'm not using it in these, only 'building'.

Code being used:

I have a python script that successfully pulls POI (points of interest) data from OSM via an overpass-API. There are three input variables to comply with the request: 'country_code', 'master_type' and 'value_type'.

Now I am making the map that we can get the location of kindergartens,but now initialRegion is Tokyo station. I would like to adjust the map as getting current location when user open the app,or something button is pressed.How can I add the code??

below is current code,and it can get the location of kindergartens when the button is pressed.

This is my JSON:

In my program, I need to make GET call, then pass returned data to another GET call, and then return results. When it is happening, I want my program to wait until data is returned.

Right now I figured out something like this:

In my app, I use Leaflet with OpenStreetMap. I also use Nominatim to get place details. I want to check whether the place is gas station. But, when I point to gas station, and get place details, the JSON file often have different "type" property. It can be:

Scenario: I want to write my own Autocomplete-API for Addresses, just like the One Google is offering. (Very Basic: Street, Housenumber, City, Postcode, Country). It is intended for private use and training-purposes only. I want to cover about 1 Million Addresses for a Start.

Technology Used: .Net Framework (not Core), C#, Visual Studio, OSMSharp, Microsoft SQL-Server, Web Api 2 (although i will probably switch to ASP.Net Core in the Future.)

Approach:

• Set Up Project (Web Api 2 or Console Project for Demo-Purposes)
• Download relevant File from OpenStreetMaps using DownloadClient() (https://download.geofabrik.de/)
• Read in the File using OSMSharp and Filter out relevant Data.
• Convert Filtered Data to a DataTable.
• Use DataTable to feed SQLBulkCopy Method to import Data into Database.

Problem: Step 4 is taking way too long. For a File like "Regierungsbezirk Köln" in the Format osm.pbf which is about 160MB (the uncompressed osm file is about 2.8 GB) where talking about 4-5 Hours. I want to optimize this. The Bulk Copy of the DataTable into the Database on the other Hand (About 1 Million Rows) is taking just about 5 Seconds. (Woah. Amazing.)

What i tried:

• Use a Stored Procedure in SQL-Server. This comes with a whole different Set of Problems and i didn't quite manage to get it Working (mainly because the uncompressed osm.pbf File is over 2GB and SQL Server doesn't like that)

• Come up with a different approach to Filter and Convert the Data from the File to a DataTable (or CSV).

• Use the Overpass-API. Although I read somewhere that the Overpass-API is not intended for DataSets above 10,000 Entries.

• Ask the Jedi-Grandmasters on StackOverflow for Help. (Currently in Process ... :D)
