Mapping and Tracing definitions

Are the definitions of "mapping" and "tracing" given here, are the accepted definitions? Is "mapping" just the process of gathering the data (akin to "surveying" perhaps), or does it also involve drawing the maps in an editor? Also "tracing" makes me think of drawing over Yahoo! Aerial Imagery or over existing maps.

If the definitions are ambiguous then we could either state the ambiguity on this page, or attempt to be prescriptive, and lay down how we should be using these words. -- Harry Wood 10:04, 13 March 2007 (UTC)

Missing ?

Could someone add the following definitions ?

• "Relations" : As defined in the "Data Primitive", "Nodes" and "Ways" are explained but not "Relations".
• "OS" : For non-british people, 'OS' is an Operating System.

OK I added them. There are lots of words we could add to the current list. Feel free to add more. -- Harry Wood 16:51, 25 February 2008 (UTC)

Missing: Redaction

Hi,

Can anybody please add a definition of Redaction?

Thank you. --Amir E. Aharoni 06:32, 2 August 2012 (BST)

Added by Aude. Thanks! --Amir E. Aharoni 09:04, 2 August 2012 (BST)

group / feature / attribute / subkey definitions

Hi,

I'm a bit confused about the usage and meaning of group/feature and attribute/subkey:

What is the difference between a feature (as used in Category:Features) and a group (as used in Category:key_descriptions_by_group) ? Is there any?

In a similar fashion, how are keys like "seamark:type=*" denominated? In this case, is "type" an attribute or a subkey? is "seamark" a key or a group (or something else altogether)? Or do subkeys mean "standalone" keys that pick up on more general ones, like in "natural=wetland / wetland=*" ?

It would be great if someone could clarify that to me and maybe it could also be included in the Glossary?

I have this problem too: I haven't found a description of the tagging hierarchy and nomenclature yet. eteb3 (talk) 11:28, 12 October 2019 (UTC)

Well, it looks like these are just two ways of categorising the information in this wiki.

In a similar fashion, how are keys like "seamark:type=*" denominated? In this case, is "type" an attribute or a subkey?

Everything before the equal sign is the key and everything behind is the value. Key and value ensemble an attribute. There seems to be no common definition for the term "subkey", but one of them would say that "type" is a subkey.

is "seamark" a key or a group (or something else altogether)?

Seamark is a part of the key seamark:type=* in your example.

Or do subkeys mean "standalone" keys that pick up on more general ones, like in "natural=wetland / wetland=*" ?

That is the second definition of the term "subkey". --Tigerfell  (Let's talk) 13:55, 13 October 2019 (UTC)

Internal links

Page policy proposal: Where the definition of a headword (A) includes a word that is also a headword (B) in the Glossary, it would be useful if there is an internal page link to Headword B. Markup question: Can such words be internal page anchors, allowing linking that is internal to the page? If so, how? And is there a bot that can do this cross-referencing automatically? eteb3 (talk) 07:21, 21 October 2019 (UTC)

You can place anchors by using Template:Anchor. I do not know any bot that does that, but there is some wiki documentation about that, too. --Tigerfell  (Let's talk) 20:42, 21 October 2019 (UTC)

Thanks. Have used a few, and linked from Overpass turbo/Wizard eteb3 (talk) 23:01, 23 October 2019 (UTC)

INSPIRE (UK only)?

Why does the page say "INSPIRE (UK only)"? It is an abbreviation for " Infrastructure for Spatial Information in the European Community". --Tigerfell  (Let's talk) 08:52, 5 April 2021 (UTC)

Thanks, I wasn't aware of it being EU-wide. I've only come across it in OSM, and then only in the UK case. (Fwiw, the reason I've added this here is that 'OSMUK Cadastral Parcels' has appeared as an overlay available in iD, but that term doesn't appear in the wiki. I've added that term in the appropriate place: this entry is trying to explain the related - and official - terminology.)

How is this for an alternative?

INSPIRE or INSPIRE polygons:  Infrastructure for Spatial Information in the European Community, a cadastral system used in the European Union. In some countries data is available to mappers, for instance in the UK through Land Registry INSPIRE Index Polygons.
