1. Scrolling Marquee
The scrolling marquee is located at the top center of the website just above the map. It
displays all current alerts for all gauges. It is continuously updated with current
alerts from all gauges, as well as any administrative/test alerts.
2. Jump to Jurisdiction
This feature allows for a dropdown with a list of political entities (e.g. counties)
that contain at least one monitoring station that is available through the website.
This allows you to quickly select an area of interest, and immediately
opens the data table for all the gauges located in the selected area.
The toolbar currently consists of 6 different tools. Those tools are as follows, in order
of likely use.
A) The information button
is the default tool when the website is loaded. This is denoted by the depressed appearance
of the button. This tool allows the user to click on any item on the map and get any
information that is available for that item through a pop-up.
B) This tool allows you to either
click on a point and zoom in, or click and drag a square around an area that you wish to zoom
into. If you have a scroll wheel, it can replace the zoom-in and zoom-out tools.
C) This tool allows you to click
on a point and zoom out. The scroll wheel can also zoom out.
D) This tool allows you to click
and drag around the map, though when using the information tool, you can click and drag around
the map without having to select this tool seperately.
E) This tool works like the
"Back" browser button, taking you back to the previous view of the map, if one is available.
F) This tool works like the
"Forward" browser button, taking you forward one view of the map, if one is available.
The legend contains all the layers that are loadable on the map, and allows them to be cut on and
off as needed. It has 2 sections, the baseLayers and the overlays. A baselayer is always on, and is
normally a road map or an aerial map. Only one can be on at a time. The overlays have no limit to how
many can be on at a time, although in general, the fewer that are on, the easier the map is to read.
Some overlays could also cover other layers, hiding them from site.
Also in the legend, there are counts of gauges, and alerts of the gauges, if any are available.
The legend can be minimized by clicking the minus symbol
in the top right of the legend. The legend may have to be scrolled to the top to see the symbol.
Once minimized, it will appear as a plus symbol that can
be clicked to bring the legend back up.
6. Navigation Tools
This set of navigation tools in the top left of the map help the user to move around the map
the same way the buttons on the toolbar do, without having to choose different tools. The arrows
simply move the map up, down, left, or right. The only exception is if the map is at its initial viewing
area, in which case it will not move. The plus and minus symbols below the arrows will zoom in and
out with a simple click. The circle/globe between the plus and the minus will automatically take the
user back to the initial viewing area of the map.
7. Overview Map
The overview map, located in the bottom right of the map, shows your location relative to a larger
area. To help with details, instead of staying fixed on a single, larger area, it zooms in to areas
as well, so you can always get the best idea of where you are. Like the legend, the minus symbol
will minimize the overview map to a simple plus tab.
Just below the overview map in the very bottom right corner of the page, the coordinates of the cursor
offer detailed location information for any item on the map.
