These days they are in digital data. A cartographer will manipulate the digital data to revise them. It's possible to create site centred maps in this way.
In the past they were fair drawn and transferred onto printing plates.
To survey a map there are a range of options. Many of the maps today were created by traditional methods as shown below.
1. Stellar observations: to fix them in the right place in the world
2. Triangulation (at different precisions, depending on the size of the map): to create a framework
3. Traversing: to create control stations in populated areas.
4. Detail Survey: to add all the detail required by the map users.
Aerial surveys and GPS make life much easier today.

The Advent wreath should be taken down before the Christmas midnight Mass begins. I think the "fifth candle" is some modern invention that makes no sense.
