How to download Google Maps Street View Static Images based on geojson

Google Maps Street View Static API

Prepare your own geojson file.
Go to Google Maps Platform and follow all steps(Get started -> Pick products Map -> Select a project -> Set up your billing) until getting you own key.
If you have registered before, you can find key in here. https://console.cloud.google.com/apis/credentials/key/
Open terminal and set Google Maps API Key in environment variables.

Convert a JSON's file tree structure

If you want to make the tree command available on mac OS X, run brew install tree.

Simply, change BASE_DIR and OUTPUT_JSON_FILENAME. Run convert-file-tree-json.py.

You can use the tree command which lists a directory structure recursively.

e.g)

Get Street Geojson using Openstreet's Nominaim API

Update street names in all-streets.txt.
Update your COUNTRY_CODE = 'sg' in geojson_generator.py.
Run geojson_generator.py
Check *.csv and geojson.json file.

Nominatim is a search engine for OpenStreetMap data. This is the debugging interface. You may search for a name or address (forward search) or look up data by its geographic coordinate (reverse search). Each result comes with a link to a details page where you can inspect what data about the object is saved in the database and investigate how the address of the object has been computed. To enhance understand of Nominatim, recommend to visit https://nominatim.openstreetmap.org/ and play for a while.

Find the nearest coordinate from a set of geographical coordinates using haversine

Basic Implmentation

function renderWithRedux(ui, { initialState, store = createStore(rootReducer, initialState) } = {}, renderFn = render) {
  const obj = {
    ...renderFn(<Provider store={store}>{ui}</Provider>),
    store,
  };
  obj.rerenderWithRedux = (el) => renderWithRedux(el, { store }, obj.rerender);
  return obj;

	feat: Summarize changes in around 50 characters or less

	More detailed explanatory text, if necessary. Wrap it to about 72
	characters or so. In some contexts, the first line is treated as the
	subject of the commit and the rest of the text as the body. The
	blank line separating the summary from the body is critical (unless
	you omit the body entirely); various tools like `log`, `shortlog`
	and `rebase` can get confused if you run the two together.

	Explain the problem that this commit is solving. Focus on why you
