osmium | C/Javascript framework for working with OSM files | Map library

[Editing this question completely] Thank you , for those who helped in building the Periodic Table successfully . As I completed it , I tried to link it with another of my project E-Search , which acts like Google and fetches answers , except that it will fetch me the data of the Periodic Table .

But , I got a problem - not with the searching but with the layout . I'm trying to layout the x-scrollbar in my canvas which will display results regarding the search . However , it is not properly done . Can anyone please help ?

Below here is my code :

All,

I've been trying to build a website (in Django) which is to be an index of all MTB routes in the world. I'm a Pythonian so wherever I can I try to use Python.

I've successfully extracted data from the OSM API (Display relation (trail) in leaflet) but found that doing this for all MTB trails (tag: route=mtb) is too much data (processing takes very long). So I tried to do everything locally by downloading a torrent of the entire OpenStreetMap dataset (from Latest Weekly Planet XML File) and filtering for tag: route=mtb using osmfilter (part of osmctools in Ubuntu 20.04), like this:

I am looking for bounding box data for individual states which exist within countries. For eg, for India - states like Andhra Pradesh, Karnataka etc or for Norway - bbox for Akershus, Aust-Agder etc.

One approach I know is download extracts from Geofabrik and use osmium-tool to get the bounding box data from that using this command -

osmium fileinfo -e -g data.bbox victoria-latest.osm.pbf

However, Geofabrik does not have the states for many countries like India, China, Indonesia, Austria, etc.

One alternative to that is to use extracts from download.openstreetmap.fr. Their extracts unfortunately have very incorrect bounding box values. For eg, the bounding box for Victoria state in Australia covers half of Australia. I've noticed this problem many of their extracts. Bhutan's bounding box covers 3x the lateral area. Malaysia's extract covers half of Indian ocean. This makes their extracts unusable to extract the bounding box data from.

Apart from this approach, there are also data sets like this - https://gist.github.com/graydon/11198540

However, these do not contain states and regions as you can see.

Where can I find this data? or, if possible, can I extract it from OSM in some way using Overpass? I am looking for any way or method to get this data. Even a comment pointing me in the right direction will help. Thanks.

so I've coded a questionnaire and I'm running into an issue. When a user clicks submit the questionnaire the results are displayed near the submit button I was hoping for them to be redirected to a new page (where results are displayed) by using the CSS hidden property, but I don't understand how I can do that and also for some reason after submitting there is an 'undefined' option displaying under the choices, how can I get rid of that? I'd really appreciate it if someone can help me solve my issues, thank you!

I linked the IDE for my project if that's easier: https://repl.it/@AS11RA/Forest-Firefighters-Website#start%20questionnaire.js

Heres the startquestionnaire.Js file:

so I've coded a questionnaire/survey for my website but for some reason when a user clicks start questionnaire the questions show but the choices aren't displayed. I'm really confused as to why this isn't working I would really appreciate if anyone can help me solve my problem, thank you!

Here's a link to my IDE as I figured it would be easier to go through it to identify any mistakes I'm making: https://repl.it/@AS11RA/Forest-Firefighters-Website#index.html

Here's the start questionnaire.js file:

I'm trying to build a really simple survey on Javascript but I keep getting this error "TypeError: startSurvey is not a function at HTMLButtonElement.onclick (/:2:54)" I would really appreciate if anybody can help me solve this error or provide any further feedback and suggestions.

Here's my HTML code:

I wanted to return the name of elements based on two conditions; even protons number and odd neutrons number. I've tried to print both tests and it turns out well. However, when I try to print the elements using 'and' logical, an error has occurred due to different broadcasting. I can't figure out how do I reshape it. Help me out.

The elements, protons and neutrons.

I've already converted elements, protons and neutrons into arrays.

The input;

I have this project for school. There is a csv file with a list of chemical elements. I have to read it, add to array list and print it out. The problem is, that this lines, that read from this file are not of a same size, for example:

• Osmium,76,Os,190.20,5773.16,3273.16,22600,678.39,26.80,
• Radon,86,Rn,222.02,

And my code, that looks like this

I am trying to import a networkx graph object as a pickle using nx.read_gpickle, and am getting an error that pyproj.crs package does not exist. Heads up that I am using GOSTnets, a package developed for network analysis using networkx, geopandas, osmnx, and peartree.

I first constructed the graph, and then projected using osmnx.project_graph and saved using GOSTnets.save:
