System Components and Functionality

Data Browser

Once a user chooses their variable and spatial and temporal resolutions within the variable picker and data cube, they can then browse their choosen data visully or numerically within the data browser section of the Arctic RIMS data explorer tool. The data browser consists of three major components, the map display, the numerical data display and the animation tool. All components work in conjunction with each other, but have specific functionalities within themselves.

The map display exhibits user choices as chosen within the variable picker and the data cube. Zoomed displays per continent, sea basin or watershed can be created and displayed by the user by choosing specific continents, sea basins or watersheds from the pull down spatial navigation selection boxes found directly below the variable picker. Upon choosing a selection from any of these selection boxes the display will redraw and display the user defined variable, temporal and spatial resolutions. Spatial resolution zooms can also be completed by simply clicking on the continent, sea basin or watershed of choice in the map display window. Once zoomed to an extent, a user can zoom back to the full Pan-Arctic extent by clicking anywhere in the ocean within the map display. Users can also pan to an adjacent watershed, sea basin or continent by simply clicking on it. The display will then be redrawn to your new extent. All data sets exhibited within the map display window have a corresponding legend of associated data values below the map display window.

Mean, Minimum or Maximum data values can be exhibited within the map display for any static data sets by simply choosing one of the radio button choices above map display window. Map values, Anomaly values or a histogram of data values can be displayed within the map display window for any non-static data sets by choosing the radio buttons that appear above the window.

Operational and Re-Analysis sites can be drawn on top of any data display by choosing the "Show Operational Sites" and "Show Re-Analysis Sites" check boxes above map display. Users can then view the names of each site by simply passing their mouse over the sites. The names of each site are then displayed within the text box to the right of the "Show..." check box choices. More in-depth stream discharge station information can be obtained by clicking on any Operational or Re-Analysis sites on the map. This information is displayed on a separate pop-up page that has a set of unique controls. The use and functionality of these pages and their controls are discussed below.

Once a user's data variable and resolutions are displayed properly within the map display window the user may query latitude, longitude, basin and sea basin values from within the displayed map by passing the mouse cursor over any pixel on the map. The latitude, longitude, basin and sea basin values associated with each pixel are displayed within the numerical data display in the Mouse Over box found to the right of the display window as the mouse cursor is passed over a location in the map display. Data values for the user chosen variable and resolutions may also be displayed within the numerical data display. In order to view these values the user must first load the data set by clicking on the check box next to the variable within the data numerical data display within the Mouse Over box. Data can be viewed for any single pixel without having to load an entire data set by clicking on the pixel. The data values associated with the pixel can then be viewed within the "Data for Selected Grid Cell" box.

Users can animate chosen temporal data sets within the map display by setting a from and a to date within the Animation window found to the lower right of the map display window. Animations are activated by clicking on the Start Animation button within this window once the dates are set. Users are also given the option to view a full time series graph of the animation date range as specified in the from and to date boxes. A single image may also be displayed for any single date in a similar fashion within the Animation window. Note that data frame dates are displayed in the upper right hand corner of the map display window when using the animation tool.
