Updated Map Interface
Modified State and Data Type selection - State or Territory and Data Type can now be selected in any order. Also, after initial selections have been made, an additional State can be added to the view, and the Data Type can be changed without having to reset the selections. Up to three States can be displayed at the same time.
Updated zoom controls - New zoom controls to drag a zoom box () and to zoom back to the previous level (). The zoom controls obscure less of the map view than in the previous version.
Added overview map control - Overview inset map in the lower-right corner. This can be optionally hidden from the main map view.
New background map options - Satellite map has been added as an option, and style of the menu has been modified to be consistent with related USGS mapping products.
Simplified list of available parameters - The general list of available parameters has been simplified to include only those that are available at most locations of a given Data Type. This is to reduce confusion where there are variations of a parameter, or where a parameter is only available at a few sites. In every case, a full list of parameters available for subscription is displayed when an individual site is selected.
Peak chart - As an aid for choosing an appropriate threshold value, a peak chart is now viewable on the Subscription Form for Gage Height (stage).
