Category:Maps by theme[edit]

This discussion is copied here from Category talk:Thematic maps by Marcel Douwe Dekker (talk) 00:40, 28 February 2009 (UTC)

There is already Category:Maps by theme. --Timeshifter (talk) 08:57, 26 February 2009 (UTC)

I created this cat because it seems to me there is a difference between "Map by theme" and "thematic map". As far as I know thematic maps are a specific main type of maps. That is confirmed in the multiple English, German, Dutch ... Wikipedia articles about thematic map.
Now I already noticed this category has been deleted before May 2006, because it was replaced by Category:Maps by theme. I created this category any way, because in my perception the "thematic map" is a "map by type", and should be listed in the Category:Maps by type. And I guess most maps in the Category:Maps by theme could be considered thematic maps.
I wish you would have first made this remark before clearing this category. This procedure is clear here. If you want to have a category removed, you first propose it and wait with removing all content. I will restore soem of it for now, to give other an impression were we are talking about here. -- Marcel Douwe Dekker (talk) 13:17, 26 February 2009 (UTC)
The reason I created this category in the first place is, because I was improving the w:Thematic map article in the English Wikipedia and was wondering, which content in Wikicommons relates to thematic map.
Now based on my own intuition, I have narrowed it down to three categories:
The German article however gives a much longer list. This makes me wonder, what should be considered a thematic map.

(unindent) As a native speaker of English I believe that "Maps by theme" means the same thing as "Thematic maps". So it is a mistake to create a duplicate category in my opinion.

I believe Category:Flow maps belongs in Category:Maps by type because a flow map is a type of map that can have different themes. The same is true for Category:Cartograms. A cartogram is a type of map that can have different themes.

So a map can be categorized both by type and theme. --Timeshifter (talk) 07:15, 27 February 2009 (UTC)

It could be that the two generally mean the same for an outsider. As far as I know both in English and in other languages, for example Dutch, the "thematic map" is a specific type of map. Why else is there a specific article about it?
I think Flow maps and Cartograms can be considered both thematic maps and type of maps. The other type of maps in the Category:Maps by type can't be considered to be both.

From reading w:Thematic map it seems that the 2 categories mean the same thing: "A thematic map is a simple map made to reflect a particular theme about a geographic area. Thematic maps can portray physical, social, political, cultural, economic, sociological, agricultural, or any other aspects of a city, state, region, nation, or continent."
Those are the same maps found in Category:Maps by theme. --Timeshifter (talk) 13:33, 27 February 2009 (UTC)
You are missing the point here that, as far as I know, the "Thematic map" is considered a specific kind of map. You are right that the given prescription could also relate to the images listed in Category:Maps by theme. That is why I added that category here in this category. -- Marcel Douwe Dekker (talk) 15:12, 27 February 2009 (UTC)
I don't know of any special meaning of "thematic map" that would distinguish the 2 categories. As far as I know the categories are exactly the same. Maybe you are trying to create a new meaning for "thematic map"? Please see:
In both categories there are maps with themes. They are thematic maps.
A flow map does not have a theme until the theme is named and there are labels for the arrows. So a flow map is a type of map. It is not a thematic map. It is a type of blank map until there is a theme that the arrows are illustrating. Such as the number of people in a migration, or the amount of goods being traded. --Timeshifter (talk) 20:46, 27 February 2009 (UTC)
Maybe your are right. Maybe flow maps are cartograms aren't generally considered thematic maps, and then the Category:Thematic maps is redundant. I will give you the benefit of the doubt, and will move the Thematic maps intro here to the Category:Maps by theme, and make the Category:Thematic maps a redirect.
Then we can close this discussion for know. I want to experience first, if this solution suits me. -- Marcel Douwe Dekker (talk) 00:39, 28 February 2009 (UTC)


{{MetaCat|64}} versus {{MetaCat}}

Why is a number being added to this template? As far as I know it does nothing. --Timeshifter (talk) 08:18, 26 October 2009 (UTC)

It does something. --Cwbm (commons) (talk) 09:32, 26 October 2009 (UTC)
What? Template:MetaCat does not say anything about adding a number. What does the number do? Why that number? --Timeshifter (talk) 09:46, 26 October 2009 (UTC)
Never took a look at the source code of the template? --Cwbm (commons) (talk) 09:47, 26 October 2009 (UTC)
If you are not going to answer the question, then I will remove the number. I doubt you are using the correct number anyway. Why would the number of subcategories matter to the use of the template? --Timeshifter (talk) 09:50, 26 October 2009 (UTC)

Why do you remove a number from a template if you don't know the function? --Cwbm (commons) (talk) 09:53, 26 October 2009 (UTC)

Because you make many mistakes. You have a poor understanding of English at times. I believe this is the relevant source code:
{{Autotranslate|1={{{1|}}}|base=MetaCat}}<includeonly>{{#if:{{{1|}}}|{{#ifeq:{{PAGESINCAT:{{PAGENAME}}|R}}|{{{1}}}||[[Category:Non-empty meta categories]]}}| }}[[Category:Meta categories]]</includeonly>
I don't understand complex wikitext like this very well. I don't think it is asking for the number of subcategories. You added the number "64" which is the number of subcategories.
I see that adding anything after the |bar| adds this hidden category:
Category:Non-empty meta categories
{{MetaCat|*}} does the same thing. So I was correct in saying that you were not doing it right, and that adding the number of subcategories is not correct. You could have just answered my question, and told me about the hidden category. --Timeshifter (talk) 20:32, 26 October 2009 (UTC)

It does not do the same thing what is straight forward to find out. --Cwbm (commons) (talk) 21:20, 26 October 2009 (UTC)

Yes it does. It adds this hidden category:
Category:Non-empty meta categories --Timeshifter (talk) 21:22, 26 October 2009 (UTC)

How many reverts from you is it gonna take till you realize that if the number matches the number of cats and when there are no files in the cat than it gets categorized into empty meta cat and if it does not match it gets categorized into non-empty meta cat? --Cwbm (commons) (talk) 21:37, 26 October 2009 (UTC)

It does not work that way. It is the number of files at the top level that matter, and not the number of subcategories. The number of subcategories does not matter. The category is considered empty when there are no files at the top level. --Timeshifter (talk) 22:12, 26 October 2009 (UTC)

Count of reverts: 1
