You needed to provide a name for the map because this is the first time you have saved it. In the File name text box, type Ozone Prediction Map.mxd.Browse to your working folder (for example, you could create the following folder to store your work: C:\Geostatistical Analyst Tutorial).It is recommended that you save your map throughout each exercise and at the end of each exercise. Mapping the data is the first step in exploring it and understanding more about the phenomenon you want to model. Note that the highest ozone values occurred in California's Central Valley, while the lowest values occurred along the coast. The symbology dialog box should look like this: Choose the White to Black color ramp so that the points will stand out against the color surfaces you will create in this tutorial.In the Fields box, set the Value to OZONE.In the Show box, click Quantities and click Graduated colors.In the Layer Properties dialog, click the Symbology tab.Double-click the O3_Sep06_3pm layer's name in the table of contents.This allows you to see the layers that you will create in this tutorial underneath this layer. Only the outline of California is displayed.
