I would like to reply myself ;
I attached 2 links for 2 short courses in GIS , In my Point of view, they are very useful :
1- University of California, Riverside , USA http://www.extension.ucr.edu/sciences/geo/summer.html
2 UNESCO-IHE , holland http://www.unesco-ihe.org/Education/Short-courses/Regular-short-courses/GIS-and-Remote-Sensing
Finally , Please tell me : 1- How did you find the courses ?? 2 - Anyone decided to apply for those courses ? 3- How did you find my English ? Is it very bad or it is good ? Thank you very much & Best Regards.
