![]() A fix was made so that one can convert Band Interleaved by Pixel formatted images to Band Sequential images correctly. The changes made in the 2022.04.09 version caused this problem.Īlso a couple new options were added to the New Channel from Function feature in the Transform Data dialog box. These are 'Latest Threshold Channel' and 'Earliest Threshold Channel'. 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). From the menu bar, File > Open Image, navigate to the Beverly.lan in the MultiSpec Sample Data folder, click Open. Opening a Multispectral Landsat Image Launch MultiSpec. 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. Using MultiSpec Open File This will show how to open and view multispectral Landsat data and how to open and view data stored in HDF or NetCDF format. ![]() One limits the channels being used to 1 to 183 range. This gives one an image of the latest spring freeze dates of the year. The 'Earliest Threshold Channel' creates an image with the day of year (channel number) before which the minimum temperature isĪlways larger than the selected threshold value. In this case one limits the channels being used to 184 to 365/366 range. This gives one an image of the earliest fall 'freeze' dates for the year.Ī status box is now displayed when linking more than 20 images together so that one knows the status of the linking operation. Universal (Apple Silicon and Intel version) 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.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. This version will work natively on both the Apple Silicon and Intel MacOS Computers. The file size is about double the usual size because it includes the code for both types of computers. One can run the Intel version on Apple Silicon computers using the 'Open using Roseta' option in the Get Info box for MultiSpec if one runs into problem with the native version for Apple Silicon computers. In the Open dialogue box, locate the filename Reno.tif and click Open. A dialog box will open to allow one to select the data file one wishes to use. 1.2 From the File menu choose Open Image. Open the Reno image, which is a Landsat 7 image a. 1.1 Start MultiSpec using the icon on the desktop or from MultiSpec in the Startup Menu. This version has only been tested on a MacBook Air with the M1 processor. MultiSpec, you will be able to change the band combinations to help identify different features in satellite images. Let me know if problems are found with any of the other Apple Silicon processors. This version uses a newer version of the wxWidgets library (3.1.5). The MultiSpec Online version will be updated after the Spring Semester classes are over. ![]() There is no way to allow users to go back to the 2020.09.09 version if they run into problems with the new version. The 2020.09.09 MacOS and WindowsOS will continue to be available for download in case users run into problems with this new version.Ĭhanges were made so the the channels descriptions will be associated for the Landsat Analysis Ready Data (ARD) sets and the Sentinel image files. Starts the receiver program.Sentenel images files will be recognized as such as long as S2A_ and S2B_ are someplace in the full path name.Ī change was made so the the histogram statistics for ERDAS Imagine formatted files will be read correctly. One of the receivers or on one of the senders, the data transfer will The program waits forĬonnections from the receivers. I've never set it up in a perfect way, so 1 or 2 transmissions usually failed, but it saved time during my classes sending a large ISO file to my students at once. It's an old software program (2006), but it still worked fine for me. The advantage of UDPcast over using other methods (nfs, ftp, whatever) is that UDPcast uses UDP's multicast abilities: it won't take longer to install 15 machines than it would to install just 2. This can for instance be used to install entire classrooms of PC's at once. UDPcast is a file transfer tool that can send data simultaneously to many destinations on a LAN.
