Shift and Option or a or ' Keys: If one holds shift and option or a or ' keys down, the cursor will change to an eye. Therefore other options are provided not perfect but the capability does work. The control key does not work in some browsers. Releasing the mouse button will change the colors back to the original. Note that whether one uses the Control or z or / keys is browser dependent. Clicking the mouse button down will change the color of all of the other classes or groups to the background color. Shift and Control or z or / Keys: If one holds the shift and control or z or / keys down, the cursor will change to an eye. Releasing the mouse button will change the color back to the original. Clicking the (left) mouse button down will change the color of the class or group to the background color. Shift Key: If one holds the shift key down, the cursor will change to an eye. One can 'blink' the color of the class or group by placing the cursor over the respective color chip in the legend or over the respective color in the image window and do the following: It is consistent with that in the desktop versions of MultiSpec. This version also includes a change in the 'blinking' operation in thematic image windows. Version 3.51 ( ) brings the code base up to the same level as that for the desktop versions of. This gives one an image of the earliest fall 'freeze' dates for the year. In this case one limits the channels being used to 184 to 365/366 range.

The 'Earliest Threshold Channel' creates an image with the day of year (channel number) before which the minimum temperature is always larger than the selected threshold value. This gives one an image of the latest spring freeze dates of the year. In this case one limits the channels being used to 1 to 183 range. The 'Latest Threshold Channel' creates an image with the day of year (channel number) after which the minimum temperature is always larger than the selected threshold value. The options were developed for images of minimum temperature in which the images have a channel for each day of the year (365 or 366 channels). These are 'Latest Threshold Channel' and 'Earliest Threshold Channel'. A message is listed in the Output Text Window indicating how many files were linked.Ĭhanges were made so the channel descriptions will be associated for the Landsat 9 data files as long as the files begin with LC9, L09, LT9, or LC09.Ī couple new options were added to the New Channel from Function feature in the Transform Data dialog box. Middle/High School Lesson: Landsat 5 Flood Lesson.Ĭhanges were made so that one can link a mixture of files in band sequential, band interleaved by line, and band interleaved by sample/pixel.Ī status box is now displayed when linking more than 20 images together so that one knows the status of the linking operation.
