Spring 2024 - Professor Xue is super sweet, but his lecture can be super technical, so it might be challenging not to fall asleep. The content discussed before the midterm is very detailed and technical, possibly one of the hardest GIS electives I have been in. The primary grade for this class is the weekly lab assignments, which can take a lot of time for the writing portion. I always got points deducted for the most minuscule elements each week, so it is better to talk to your TA regarding your work and expectations. Midterms are challenging but not too hard to do if you study well. I did not enjoy the first half of the class much, but I found the latter half to be very useful, especially if you want to continue remote sensing as a career.

Winter 2026 - I thoroughly enjoyed taking GEOG 182B with Professor Zhou. This was my second quarter in a row taking one of his GEOG 182 series courses, and I could not be more pleased with how well the series is structured. The class is well paced and clearly instructed. Professor Zhou is highly knowledgeable about remote sensing, and he also provides helpful insight into where the field is heading and how these skills apply in practice. This course is great for anyone interested in developing a deeper understanding of image processing and the nuances behind remote sensing analysis. Professor Zhou also offers a lot of flexibility and understanding regarding assignments and expectations. If you put in the effort and stay curious, you will do well in the class. Easily one of the best professors I have had at UCLA!
