Template:Location/attribute documentation

Information attributes - used to pass to GeoHack server metadata about the coordinates. Apart from heading, this information is not used by {{Location/attribute documentation}} template. Attributes have to be in the format field1:value1_field2:value2_field3:value3, etc. The following fields are supported:

region:XX-YYY specifies the political region, used to select appropriate map resources. See here for more info.

XX is an ISO 3166-1 alpha 2 country code abbreviation, and
YYY is a 1-, 2- or 3- characters ISO 3166-2 (see en:ISO 3166-2#Format for details) province/region/state code abbreviation (typically the same as a local postal code abbreviation).

heading: indicates the direction in which the camera was pointing. It is given as degree values 0–360 (clockwise with north as 0) or a compass point abbreviation (up to four letters) as defined in Points of the compass. (Example: heading:NW). It should be very similar for both {{Location}} and {{Object location}} templates when used in the same image. For example "heading:N" means that the camera was pointing North when the photograph was taken. In case of {{Object location}} template that might mean that we are looking at a South wall/side of the structure/object.
scale:N specifies the desired map scale as 1:N. Since most images are at the lowest scale, the parameter should be given only if values different from the default are desired. See here for more info.
dim:<width><units> specifies the width of the object in meters or kilometers (example: dim:120m or dim:10km). Since most images are at the lowest scale, the parameter should be given only if values different from the default are desired. See here for more info.
source: where the data come from
class:object is a hard-coded value which will be added automatically to all images to tag this location as the "object" location.
