You are looking for things like:
● Street signs (name of roads and amenities)
● Place name and boundary signs
● Business signboards (the name, branch, address, etc)
● Get extra data from your official receipts & flyers
(name, operator, branch, building name, address,
phone, etc.)
● Identify (or verify the existence of) map objects: eg.
bus stops, fuel station, shops, banks, hotels,
restrooms, historical markers, bridges, health centers,
barangay halls and anything of interest to the general
public.

Tagging
Map Features

30. osm
Many tags we use are common and intuitive.
They are already in your Editor's preset icons.
There are more than 43 categories and hundreds
of individual types of data that are gathered.
You can't possibly memorize or use all of them,
as they are continuously changing. It's a wiki.
Do yourself a favor. Bookmark the following link

● L = straighten Line
● O = align in a circle
● Q = make right-angled
● Shift-B = distribute nodes
● Shift-P = make parallel ways
Working with
Junctions:
● M = Merge Nodes
