To go along with my recent forum post Bookmarks – We’ve Got Bookmarks!, I have developed a tool to produce properly formatted JSON bookmarks from a feature class. Download the zip file below and extract it to your C:\Users\[USERID]\AppData\Roaming\ESRI\Desktop10.3\ArcToolbox directory. After adding the toolbox to ArcCatalog, you are ready to go.
- Select any polygon feature class
- Select the text attribute to use as the bookmark label
- Decide where you want the output JSON file to be stored
- Optionally, you can choose to do a temporary dissolve on the name field, so you have one bookmark for multi-part areas that have the same name; no change is made to your feature class and the temporary file is stored in memory
The resulting JSON file is formatted properly to insert into the Web Map code as described in the above-mentioned forum post. This should enable you to create just the bookmarks you need for your applications.
Go forth and bookmark.
