معرفی : پردازش حجم زیاد داده های جمع آوری شده توسط ناسا و دیگر سازمان ها یکی از بزرگترین چالش های موجود در حیطه علم سنجش از دور است. از طرفی بین مبانی تئوری مانند مدل های فیزیکی و آماری و کاربرد های عملی سنجش از دور عموما یک خلا احساس می شود. آقای دکتر لیانگ در دانشگاه Maryland که یکی از موفق ترین دانشگاه ها در حیطه سنجش از دور است تدریس می کنند. کتاب quantitative remote sensing of land surface حاصل تجربه ایشان طی سال ها تدریس می باشد. در ادامه مطلب می توانید فهرست این کتاب را مشاهده کنید.
با افزایش کاربرد های سنجش از دور در پروژه ها و طرح های تحقیقاتی نیاز به یادگیری این دانش را روز به روز بیشتر کرده است. کاربرد های متعدد سنجش از دور و محدودیت های ماهیتی آن سبب گشته که مشتاقان به یادگیری این علم سردرگم شوند. از یک سو ارائه مطالب پایه و تئوری سنجش از دور با ماهیت کارگاهی آن در ذهن مخاطبان مغایرت دارد و از سوی دیگر عدم آگاهی از این مفاهیم سطح بهره برداری را از دوره های آموزشی بسیار پایین می آورد.
