Hi,

Can someone tell if first if its possible and secondly how to do this: I have dog ownership and breed information per property parcel in a SQL server database (Tempest) currently linked to a cadastral spatial layer and id like to theme that based on dog breed.

thanks

Ken

  Ken, are you wanting to do this entirely from GE? I'm too new to GE to know if that's possible, but it would seem to me that the better way to accomplish this is to join your external database table to your cadastral in ArcMap and publish it as a map service to consume in GE.

  If your data doesn't constantly introduce new values (i.e. additional breeds that weren't in the dataset when you published it) the service will update accordingly whenever you make changes to the external table. You can plan ahead and create "dummy" data in order to generate unique symbols, then delete that dummy info. Your symbols will remain, there just won't be anything represented in the map until your table contains a parcel with that value.

  I do this with appraisal value data from our County Assessor. We get a monthly download (text files) that gets processed into a handful of tables in SQL Server. The table is joined to our parcel layer and I symbolize the appraisal values according to the desires of my users.

  I am using ArcGIS Online along with GE (HTML5). So what you guys suggested, is possible to do with my architecture? 

   

  I have SAP Database and would like to llink it with GE to display labels (as feature layers from AGOL never draw labels ) and then render them thematically based on unique values.
