Update (September 30, 2020):<\/strong> I’ve edited this article (and the download for the .stylx file) to use version 3.0 of the dictionary style. The changes are minimal but were enough to frustrate users trying to implement these instructions with a newer version style file. For those who may still need to use the older version, I’ve indicated the correct syntax for version 2.0 where it differs. The dictionary renderer toolkit describes how to upgrade a style to version 3.0<\/a>.<\/p>\n"},{"acf_fc_layout":"sidebar","content":" OK, so it’s not that kind of dictionary. While not nearly as wordy and weighing significantly less, an ArcGIS dictionary style shares one important quality with a traditional dictionary, the ability to look up information using a provided value. I’m not just talking about looking up a symbol using a unique identifier … any style can do that. What makes a dictionary style special is built-in logic to determine which symbol to return based on input values. The symbol generated may be the result of several symbol primitives, cobbled together to appropriately represent all of the input values.<\/p>\n For my custom style, I thought it would be cool to create a dictionary style for symbolizing restaurants. I wanted each restaurant symbol to impart as much information as possible. Things like: food style, open and close time, star rating, price range, and so on.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":595892,"id":595892,"title":"Restaurant symbol components","filename":"RestaurantStyle.png","filesize":8126,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/mapping\/create-custom-dictionary-styles-for-arcgis\/restaurantstyle","alt":"Restaurant symbol showing lots of info","author":"8512","description":"","caption":"Each component of the restaurant symbol will be generated by the dictionary style based on input attribute values.","name":"restaurantstyle","status":"inherit","uploaded_to":595212,"date":"2019-08-28 16:51:30","modified":"2019-08-29 16:21:54","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":448,"height":185,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle-213x185.png","thumbnail-width":213,"thumbnail-height":185,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","medium-width":448,"medium-height":185,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","medium_large-width":448,"medium_large-height":185,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","large-width":448,"large-height":185,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","1536x1536-width":448,"1536x1536-height":185,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","2048x2048-width":448,"2048x2048-height":185,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","card_image-width":448,"card_image-height":185,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2019\/08\/RestaurantStyle.png","wide_image-width":448,"wide_image-height":185}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"sidebar","content":" Dictionary symbology has traditionally been used to symbolize features according to established military specifications.

Until recently, the logic to apply symbols from a dictionary style hid deep in the bowels of ArcGIS and was limited to styles based on a handful of military specifications. This logic now enjoys the light of day as a JSON configuration string and an Arcade script that happily coexist with the symbols in the style. This means that not only the symbols, but also the way in which they are applied can be customized and packaged into the style.<\/p>\nLet’s give it a try<\/h2>\n
