Slice/Profile Selection

The Slice/Extraction Options frame needs to be set first before a profile can be extracted from EFDC. There are three options shown in Figure 1. The user may either select a value of I to extract the active J cells along that I, or select a value of J to extract the active I cells along that J. The third option is to use a "Drape Line", which is a polyline in the same coordinate system as the LXLY data. The I & J's from along the line will be assembled and the profile will be output along that slice.

If an I or J extraction is used, the user can use the + /- keys to scroll up and down the selected coordinate. For example, if the I5 was selected, the + keystroke would display the I6 section, the – keystroke would display the I4 section. This feature is not applicable to the "Drape Line".
