GUI - Copying Images and Grids (Continued)

Copying Grids

The grid copy GUI has fewer options than the image copy GUI, but it still allows you the significant ones, like choosing specific beginning and ending grid numbers, along with the option to delete the destination set you will be copying the grids to.

In this lesson, you will copy the March 12, 1993 12Z 500 mb NGM height grid forecasted for 00Z on March 14. The test dataset "Blizzard" will be used because as of McIDAS-X 2006, the GRDDISP and GRDCOPY GUIs do not support GRIB data served from a database, which is how McIDAS-XCD stores real-time grids. Although no real-time data will be used in this exercise, you will still learn the basics of copying grids with the grid copy GUI.
