Strengths

easy to enter

  • Well known set of templates
  • Data entered into template is validated (input validation)
  • Less overhead (2-3 subtemplates only). Can be included numerous times in tables (an estimated 3880 times in discussed sample)
  • partial support for microformat
  • supported by google
  • supports "name="
  • Frequently used (was)
  • One template for all input formats (dec/dms)
  • dec/dms format can be set in user stylesheet
  • well documented
  • input validation recently added
  • Frequently advocated
  • supported by google
  • supports microformat
  • supports "name="
  • Frequently used
  • uses of older templates are currently being migrated to this format using a bot
  • Data entered into template is validated (input validation)
  • One template for all input formats
  • named parameters for coordinates (NS=/EW=)
  • named parameters for type/region/globe etc.
  • Less overhead (5-10 subtemplates only).
  • can display text/icons instead of coordinates
  • support for elevation
  • supports microformat
  • supports "name="
  • Frequently used (in German Wikipedia)
Weaknesses

can't be parsed

coordinates need to be entered twice

  • type/region/globe/etc. parameters all gobbled up
  • d/m/s are entered in separate fields
  • to switch from dec to dms input, one needs to switch templates
  • not supported by mediawiki
  • type/region/globe/etc. parameters all gobbled up
  • coordinate parameters all gobbled up
  • display=title, display=inline,title lengthy
  • Many subtemplates (15-20). Its post-expand include size limits the number of coordinates that can be included in lists (689 times in sample discussed below)
  • rounding problems for dms display
  • d/m/s are entered in separate fields
  • not supported by mediawiki
  • more verbose format (15-20% more to type)
  • several subtemplates (5-10). Its post-expand include size limits the number of coordinates that can be included in lists (425 times in sample discussed below)
  • not supported by mediawiki
Risks
  • A series of templates rather than one
  • Complex template
  • more to convert if adopted
Opportunities
  • Interwiki standardisation
