StreamerRT March 2010
Overview StreamerRT is a real‐time weather decision system. StreamerRT was built to provide a fully interactive mapping platform with a comprehensive collection of weather data. Monitor real‐time station observation data from the WeatherBug network and overlay numerous enhanced data sets to stay up‐to‐ date with significant weather events before and after they develop. Use StreamerRT to create the specific custom view that is important to you and then monitor your weather through easy access to your custom views, slideshows and animations.

Navigation
Map Tip The user can view a station point or other data layer Map Tip information by selecting a data
point and left‐clicking on that point when these data layers are enabled. Once the Map Tip is enabled, you can click for further details (Dashboard) by clicking on the “Details” link found at the bottom of the Map Tip. Data layers with Map Tip information include Station Points, NWS Alerts, Forecast Points and Tropical Information. If the Map Tip information does not display when the data point is selected and a left‐mouse click is performed, check to make sure it is the top data layer on the map. A data layer can be brought to the top by selecting the ‘Top’ control from the Data Pane. After the Map Tip displays it can be moved anywhere by simply left‐clicking on the window and dragging the mouse to place in a new location.
Zoom‐In A user can zoom‐in by selecting the Zoom‐In button or by double clicking on the map or by using the mouse scroll wheel. Choosing one of these options will produce a zoom of 50%, centered on the middle of the map. In addition, the user can select draw a zoom box to better zoom to a specific area.
the area zoom button to
Zoom‐Out A user can zoom‐out by selecting the Zoom‐out button. The view will zoom out 50%, centered on the middle of the map.
Pan A user can pan the map in 8 directions by clicking on the pan wheel. A user can also left click anywhere on the map and drag the map in any direction.
Full Extent When the user selects this icon, the map will zoom out to the default full extent of the US.

Drawing Tools
StreamerRT has four (4) tools for managing distance measurement overlays.
Location of Tools Tools are located on lower menu bar between the navigation tools and the saved views.
Functionality of Tools Line, Circle, Square Æ Clicking on a tool activates it for drawing. Æ Left mouse click on the map to drop the location point you want to measure from and then drag the mouse to the distance or point of interest. Æ Releasing the right mouse button will set the distance drawing on the map. • For a line, when clicked, a “drawing properties” window will open and display the lat/lon points and the distance of the line. • For a circle, when clicked, a “drawing properties” window will open and display the center point lat/lon and the radius distance of the circle. • For a square, when clicked, a “drawing properties” window will open and display the top left point lat/lon and the height and width distances of the square. Eraser Æ The eraser removes “active” distance drawings. • To remove a drawing, by right clicking on the line of a distance drawing layer it will change from red to blue. • Clicking on the eraser symbol will activate the eraser function. • Clicking on the blue drawing will remove it from the map. Other functionality • Multiple distance drawings can be added at once. • Layers will relocate and resize as the active map is zoomed and panned. • If multiple distance drawings are drawn on a map, right clicking on a drawing will activate it and display the location specs in the “Drawing Properties” box in the upper left.
Refresh and Clear When a user selects the Refresh button in the Data pane, the data layers currently displayed on the map will refresh. When a user selects the Clear All Layers button in the Data pane, the map and data pane will be cleared of all data layers.

Data Menu
Map Layers
Map Layers include County and State Boundries which will overlay all map layers with black borders. It is best to only use the County Boundries layer on close zoom, otherwise they may take extra time to draw. Each data menu category will allow the user to turn on a single layer using a radio button or multiple layers using one or more check boxes. Generally only one point layer can be enabled at a time and one contour layer can be enabled at a time per category. When a data item is enabled it will become visible on the map and an entry will be entered in the data pane on the right of the application. As the user selects data layer entries from the menu options, the Streamer map display will refresh to include the newly selected data. Station point data displayed on the map is auto‐updated every 1 minute.
Alerts View National Weather Service (NWS) issued warnings, watches and advisories. These include Severe Thunderstorm and Tornado watches and warnings in addition to Flood, Winter, Fire and numerous other severe weather warnings.

Click on the Details link (lower left of alert Map Tip) to launch the detailed alert information screen.
WeatherBug Severe Weather Alerts Severe weather alerts are generated from the WeatherBug Protect alert detection and notification system. Real‐time weather conditions are tracked and monitored using the proprietary WeatherBug Network for conditions such as extreme temperatures, wind, rainfall, wind chill, heat index and lightning. Alerts are generated and mapped to 5km by 5km grid squares for the continental US.
WeatherBug Protect – Heat Index – WeatherBug proprietary 5km by 5km alert grids indicating real‐ time heat index values above 90 and 100 degrees Fahrenheit
