Mapping process and community
Mapping success stories
TODO : Success stories are designed to highlight important contributions. Have you significantly improved the cartography of a country (added a new line, a power station, etc.)? Don't be shy, let us know below.
- Example : NAME [DATE YYYY-MM-DD]: My success stories in words.

Use of mapping strategies
TODO : Mapping strategies refer to Power networks/Guidelines#Mapping strategies. They are used for a methodical improvement of the OSM database. Once you have fully applied a strategy in this country, you should add or update your name, the date, the strategy, and a comment below. This way, other users can see whether it is worthwhile to carry out further investigations.
