Template:Infobox terrestrial impact site/doc

This infobox documents a terrestrial impact site, an impact crater or impact structure on Earth (separate templates exist for impact sites on the moon and other planets).

Usage

Fields should generally be directly from the source, such as the Earth Impact Database or Impact Field Studies Group impact list. Wikilinks and expansion of abbreviations are acceptable.

Impact crater/structure theories which have been disproven or are considered to have low confidence should not use this infobox. Editors are encouraged to remove the infobox from disproven/unlikely crater theory pages immediately without waiting to ask for permission.

Example infobox

The following parameters can be used to create a terrestrial impact site infobox. Please remove any parameters that are not likely to be useful.

Parameter documentation

Field	Description
name	Name of the impact site. This field is required.
other_name	Other name for the impact crater or structure if relatively well known. For example, Meteor Crater for Barringer Crater. Quotes can be used as normal to italicize or bold the text if desired.
photo	Photograph of the crater or structure. Preferably this should be a distance or aerial shot to show most/all of the crater or structure rather than a view from within it. Do not include the "File:" prefix. If uploading a new image, please put them on Commons so they can be easily used by the other language Wikipedias. If the only image available is less than 300px wide, you can use the photo_size parameter to indicate its size.
photo_size	Specify the width of the photo in pixels. For example, photo_size = 200 with no "px". If no value is specified, the default width is 285 pixels. A standard horizontal photographic composition will generally display well at 285px. A standard vertical composition may need to be adjusted to 180 or 220 pixels.
photo_alt	Alt text for the photo, primarily for visually impaired readers. See Wikipedia:Alternative text for images.
photo_caption	Description of the photograph which is displayed below. Include the month and year if known.
map	The name of a location map as per Template:Location map (e.g. Indonesia or Russia). The coordinate fields (e.g. lat_d and long_d) position a pushpin coordinate marker and label on the map automatically. Example see: Mount Everest
map_alt	Alt text for the map, primarily for visually impaired readers. See Alt text for maps and diagrams.
map_caption	Fill out if a map caption is desired. If not specified, location will be used.
map_size	Must be entered as only a number—no need for px. The default value is 250.
location	Province or state first, followed by country. For USA, the county is optional but if given, be provided before the state. If a pushpin map is being used, the location will be used for the map's caption unless the map_caption parameter is set.
label	Label to be used for the impact crater or structure's location on the map. If not specified, the value of the name parameter is used.
label_position	The position of the label on the pushpin map relative to the pushpin coordinate marker. Valid options are {left, right, top, bottom, none}. If this field is not specified, the default value is right.
coordinates	The latitude and longitude of the summit using the {{coord}} template with display=inline,title. If the article uses a geolinks template in the external links section, do not use the display parameter.
coordinates_ref	For any references regarding the coordinates reported. <ref> </ref> tags must be used.
confidence	If the reference is the Earth Impact Database then this field should be "confirmed". Otherwise, if from the Impact Field Studies Group impacts list, use the classification "confirmed", "most probable", "probable", or "possible". This should include a citation, such as from {{Cite Earth Impact DB}} (for confirmed impact sites). Do not list impact theories which have no listing, or are listed as "improbable", "rejected" or "proposed". Even if you see a story in the news, give the scientists time to classify them. This field is required.
diameter	Diameter of the impact crater or structure. Impact listings always use metric units. On Wikipedia, for the international audience, these listings should include a conversion to imperial units.
depth	Depth of the impact crater, in metric units. This listing should include a conversion to imperial units.
rise	Height of the crater rim above the surrounding area, if applicable, in metric units
imp_size	Size/diameter of the impact crater progenitor in kilometers/meters.
age	Age of the impact. Geologic time scales may be useful here.
exposed	"Yes" if the impact crater or structure is exposed at the surface. "No" if not.
drilled	"Yes" if the site has been drilled by geologists. "No" if not.
bolide	The type of bolide (impactor), if known. Examples include "chondrite" or "iron". Use what the source says.
translation	If the impact crater or structure name is not in English, the English translation.
language	The language of the translation.
pronunciation	Pronunciation of the name if not obvious.
topo	The name of the topographic map showing the impact crater or structure. In Canada, this is usually the National Topographic System map number while for the US, it's the map name from the USGS. For large structures, it is probably not worthwhile to list. This should not be included for buried structures (since they won't appear on the topo map.)
access	The access route to the site.
country	The country where the impact crater or structure is located.
state	The state where the impact crater or structure is located. (This is mutually exclusive with province.)
province	The province where the impact crater or structure is located. (This is mutually exclusive with state.)
district	The district where the impact crater or structure is located.
municipality	The municipality where the impact crater or structure is located.

General notes

• The name and confidence fields are required. Optional fields will not display if not present in the template or do not have any value.

Microformat

The HTML markup produced by this template includes an hCard microformat, which makes the place-name and location parsable by computers, either acting automatically to catalogue articles across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to an address book. Within the hCard is a Geo microformat, which additionally makes the coordinates (latitude & longitude) parsable, so that they can be, say, looked up on a map, or downloaded to a GPS unit. For more information about the use of microformats on Wikipedia, please see the microformat project.

Sub-templates

If the place or venue has "established", "founded", "opened" or similar dates, use {{start date}} for the earliest of those dates unless the date is before 1583 CE.

If it has a URL, use {{URL}}.

Please do not remove instances of these sub-templates.

Classes

hCard uses HTML classes including:

• adr
• agent
• category
• county-name
• extended-address
• fn
• label
• locality
• nickname
• note
• org
• region
• street-address
• uid
• url
• vcard

Geo is produced by calling {{coord}}, and uses HTML classes:

• geo
• latitude
• longitude

Please do not rename or remove these classes nor collapse nested elements which use them.

Precision

When giving coordinates, please use an appropriate level of precision. Do not use {{coord}}'s |name= parameter.
