In the run up to Christmas my children have been learning about the traditions of other countries and I've just found the "Santa's of the world" story map. Perhaps it was a compromise on the different gift giving tradtions that the ArcGIS Online release was in mid-december??
ArcGIS Online gets a query tool
Find Existing Locations has been added to the Analysis options for layers. You get to define multiple query statements, both 'Where' clauses and spatial queries, and then run them as a single query. The results are copied to a new layer, which can then be symbolised and included in other webmaps. As well being a flexible analysis tool, this could also be useful for extracting subsets of data from a hosted feature service.
View only mode in the ArcGIS Online Viewer
If you access a webmap through the ArcGIS Online Viewer without logging in thenn the interface is simplified. The interactive tools are hidden and replaced by a Modify Map button.
