<br />. <br /> <br />. <br /> <br />. <br /> <br />When Rain Display is turned on current rainfall is displayed as a eolor overlay on the map, The <br />Legend eontains rain intensity scaling as well as other information, For addtional information about <br />the rain overlay, read about the map display of rainfall intensity. Previous images can be replayed in <br />rapid suecession to traek storm development and movement. The reattime operational nature of <br />STORM Wateh allows users to see he aceumulating rain data through a sliding time window. The <br />duration, or rain period, of that window- from a few minutes to several days- is set by the user. The <br />update frequency of the data displayed, called the proeess interval, is also set by the LSer (see <br />System Parameters), <br /> <br />As rain data are received, the sensor totals are updated individually by adding the new rain amount to <br />the total for the eurrent time interval. At the next processing interval, the rain totals for the last rain <br />period length of time are calculated, resulting in a new overlay and new sensor totals, The new <br />overlay and totals drop aeeumulated amounts from the older processing interval, and include the data <br />from the latest proeessing interval. <br /> <br />Other hands-off display information <br />Shapes and colors show sensor statuses in the selected Sensor Group on the map: <br /> <br />. Green dot means the sensor is active, <br /> <br />. Red or yellow dot means a sensor is registering an alarm state, <br /> <br />. Red or yellow starburst shape indieates a pending alarm at the site (notfication on, <br />unaeknowledged), <br /> <br />. Yellow cheek means the sensor has not been heard from within a usel'speeified time, <br /> <br />. White X-ed box means the sensor has been taken out of serviee, <br /> <br />. <br /> <br />An extra-large symbol is shown for sensors that transmitted during the current <br />proeess interval. <br /> <br />. <br /> <br />Sound (a beep or bell) as an indieator of ineoming data can be turned on and off with <br />Sound, <br /> <br />Site description <br />Move the mouse over a site to view a label with the site name and the sensor ID for the sensor group <br />being displayed, If the SEnsor group All Sites is checked just the site name appears and either the <br />site names or the numerie I D are displayed instead of data, <br /> <br />11 <br />
