I'm sorry if I'll write something which you know already. Survey on the lovest level is the basic structure unit of data in Therion. It could be something as log of one survey trip including surveying data. It usually include the definition of map of particular part of cave surveyed which is used as control when drawing particular scraps. Therion is able to generate map without a map definition, but in that case it looks for all available data in surveys structure and the result is sometimes unexpected. So very good rule is to define map(s) and "select" particular map in .thconfig file. Maps could be defined on base of surveys or on base of scraps.
Very important: Structure of maps is independent of structure of surveys!!! You may define as many different maps as you want and select relevant map in export definition (.thconfig file).
Surveys in higher levels usually define parts of cave, bigger unit of cave system, caves from an area, caves from a mountain, caves of a state, ....., caves on the Earth.
In such case you should use the "path" in name of survey or scrap:
xxx@aaa.bbb.ccc.ddd.eee Something as an email address.
But map may be defined by two (or several) scraps from different surveys or cave system if necessary too when you are looking for connection for example.
