Step-by-step dVoy rendering example

The following steps will guide you through loading satellite and ground monitoring data and changing rendering settings to generate a display focused on the Idaho fires and smoke during August 2000. Red outlined circles, ovals, and rectangles and green arrows in the images below indicate boxes or buttons you will be working with in generating the display.

Load Data Go to the dVoy Data Catalog and select the IMPROVE, OGC Map, and SEAW_US data sets. Then click the ‘Add Layer(s)’ button. IMPROVE is a point data set of air pollution data, OGCMap contains political boundaries, and SEAW_US is SeaWiFS satellite images over the US.
A few seconds after clicking the ‘Add Layer(s)’ button, your screen should look like the image to the right with a map displaying the data, a time series for the currently selected IMPROVE station, and a control panel. Change Date Change the time for the IMPROVE and SEAW_US layers to August 19, 2000 (2000-08-19). Then click the ‘Apply Changes’ button.
After clicking the ‘Apply Changes’ button your screen should look like the image on the right with the IMPROVE and SEAW_US data sets displaying data for Aug. 19, 2000.
