These are templates that generate external links to the United States Geological Survey's Geographic Names Information System.  Template:GNIS Template:GNIS generates an external link to a GNIS page. The only required parameter is the GNIS Feature ID number (optionally, this parameter can be named id) and the template then uses the article title as the anchor text:   {{GNIS|ID}}  {{GNIS|id=ID}}  To have the link text be other than the article name, use a second parameter (optionally, this can be named name):   {{GNIS|ID|Name}}  {{GNIS|id=ID|name=Name}}  This can be used when the Wikipedia page name contains disambiguation brackets; for example, at the page: Mount Washington (New Hampshire), use  to have "" rather than "". This is also necessary should you need to add a link to an article about somebody or something other than the linked feature.  Antarctica For GNIS pages in Antarctica, use the type=antarid parameter and the corresponding Antarctic GNIS ID:   {{GNIS|ID|Name|type=antarid}}  {{GNIS|id=ID|name=Name|type=antarid}}  Template:GNIS 2  generates a footnote-type link. The only required parameter is the GNIS Feature ID number (optionally, this parameter can be named id):   {{GNIS 2|ID}}  {{GNIS 2|id=ID}}  If desired, the template can display the feature name as the anchor text, which must be specified in a second unnamed parameter (optionally, this can be named name):   {{GNIS|ID|Name}}  {{GNIS|id=ID|name=Name}}  Examples:  {{GNIS 2|871352}}  {{GNIS 2|871352|Mount Washington}}  Results:  Antarctica For GNIS pages in Antarctica, use the type=antarid parameter and the corresponding Antarctic GNIS ID.  Examples:  {{GNIS 2|2828|type=antarid}}  {{GNIS 2|2828|Clarke Glacier|type=antarid}}  Results:  Template:GNIS 3  generates a bare URL. The only required parameter is the GNIS Feature ID number:   {{GNIS 3|ID}}  Example:  {{GNIS 3|871352}}  Result:  Antarctica For GNIS pages in Antarctica, use the type=antarid parameter and the corresponding Antarctic GNIS ID.  Example:  {{GNIS 3|type=antarid|9763}}  Result:  Use in a template {{Cite web | url = {{GNIS 3|112837}} | title = Wheeler Lake | work = [[Geographic Names Information System]] | publisher = [[United States Geological Survey]] | accessdate = 2009-07-05 }}  Result:  Template:GNIS 4  generates an external link which displays the GNIS Feature ID number. The only required parameter is ID number (optionally, this parameter can be named id):   {{GNIS 4|ID}}  {{GNIS 4|id=ID}}  Example:  {{GNIS 4|871352}}  Result:  Antarctica For GNIS pages in Antarctica, use the type=antarid parameter and the corresponding Antarctic GNIS ID.  Example:  {{GNIS 4|2828|type=antarid}}  Result:  Instructions  Go to http://geonames.usgs.gov/pls/gnispublic/  Search for the name, location, and / or type of the feature desired, e.g., to find a mountain called 'Mt. Foo', put 'mount foo' in the Feature Name and select 'Summit' for the Feature Class.  Copy the 'ID' and insert it into:  {{GNIS|...}} or {{GNIS 2|...}}  You can also copy the latitude and longitude and use them in the  template, inserting the '' vertical bar in-between, e.g.: 44_16_13_N  071_18_12_W → {{coord|44|16|13|N|071|18|12|W|region:US}}  Parameters  Parameter Required or Optional Description {1}  id= Required GNIS Feature ID, a number without leading zeros {2}  name= Optional GNIS Feature Name (only in Template:GNIS), defaults to {{PAGENAME}} type= Optional antarid (for locations in Antarctica)  See also  Special:Linksearch/geonames.usgs.gov  Special:Linksearch/geonames.usgs.gov/pls/gnispublic/f?p=gnispq  Template:Cite gnis  Template:Mountain index row  Template:Cite cgndb (Canada)  Template:Cite bcgnis (British Columbia)  Template:GPN (Gazetteer of Planetary Nomenclature)
