Today was our last full day of the internship. In the morning, all of the interns presented their power points and we all gave each other pointers. Afterwards, i finished processing an image from 1999 and then doing two subtractions; I also finished my power point. These past weeks have been very enriching and I have learned a lot. Hopefully everything goes well tomorrow; wish me luck!

Today we had our last intern meeting, and I worked on editing and finishing up my power point. We had our last pizza talk; four undergraduates presented the work they have done over the summer. After lunch, I met with Dr. Vodacek and he said that for clarity and consistency I should use SAVI, which is a simplified version of MSAVI. While this switch is easy, one of the images (July 1999) did not process correctly, so I emailed Dr. Vodacek and hopefully we can quickly fix it tomorrow. I finished everything else that I could without the image and submitted my power point to Mr. Pow for the dry run through tomorrow.

It's crazy that today is the last Monday of the internship! I spent today subtracting MSAVI images in band math; the images appear white, showing that the vegetation in earlier years was not as strong as the vegetation that grew in more recent years. After doing these subtractions, I spent the remaining bulk of the day making progress on my power point for the final presentation this Friday!

Today I worked on using the MSAVI images and applying them in order to show a change over time. I showed this by subtracting two SAVI images through Band Math. I also need to normalize this newly subtracted image, so I will do that in band math. Dr. Vodacek also gave me a lot of direction on how to create my presentation; he said my presentation should be like a story of what has happened in the park. These pointers were extremely helpful and I feel much more confident in what I am doing and where I am going. In addition, I worked on my final presentation power point and submitted my final abstract. Finally, I attended the weekly Remote Sensing meeting and I sat in on a talk about life on Mars. I will be gone the rest of the week, so there will be no updates until Monday!

Today was a pretty slow day as I have finished computing MSAVI and Dr. Vodacek was not in. So, I reviewed the MSAVI which I computed and I made sure the dNBR for all the images with SAVI showed a presence of fire. Two of them did, and two of the images I originally did MSAVI for were for the month after the fire instead of the month before, so I had to redo MSAVI with an earlier month from those two months. For these months I also fixed the NBRs and dNBRs. I spent the rest of the day by starting the power point for the final presentation.

I cannot believe that this week is the second to last week of the internship; time has flown! Today, I finished finding MSAVI for the 2000s and 2010s image. I also cropped the images because I want the MSAVI to just report data from savanna vegetation; part of the park is very dense vegetation and lakes, and I do not want these values to influence the data. I do not know where to go from here, and Dr. Vodacek was not in today. So, I spent the rest of the day doing dNBRs and NDVIs because I know these will provide additional information and probably be useful later on.
