MODIStsp can be also executed as a “stand-alone” application (i.e., without having to open R/RStudio).
To be able to do that, from R launch the function
?install_MODIStsp_launcherfor details and path customization.
Double-clicking these files or launching them from a shell without parameters will launch
MODIStsp in interactive mode, by opening the GUI. Non-interactive mode can be triggered by adding the “-g” argument to the call, and specifying the path to a valid Options File as “-s” argument:
MODIStsp -g -s "/yourpath/youroptions.json" (see
MODIStsp -h for details).
your_r_library\MODIStsp\ExtData\Launcher\MODIStsp.bat -g -s "yourpath/youroptions.json" (see
C:\Users\you\Desktop\MODIStsp -h for details).
If you do not want to install any link, launchers can be found in the subdirectory “MODIStsp/ExtData/Launcher” of your library path.
Stand-alone non-interactive execution can be exploited to periodically and automatically update the time series of a selected product over a given study area. To do that, you should simply:
MODIStsp GUI, define the parameters of the processing specifying a date in the future as the “Ending Date” and save the processing options. Then quit the program.
Schedule non-interactive execution of the MODIStsp launcher script installed as seen before (or located in the subdirectory “MODIStsp/ExtData/Launcher” of your R library path) as a windows scheduled task or linux “cron” job according to a specified time schedule, specifying the path of a previously saved Options file as additional argument:
0 23 * * * /bin/bash /usr/bin/MODIStsp -g -s "/yourpath/youroptions.json"
-g -s "X:/yourpath/youroptions.json"as argument.
