My EOI project is urban change detection, which will use Python and Orfeo Toolbox to process VHR images.

Object-based Analysis and Coding for classification

It has been more than one month since last reflection, and I have made huge progress since then. My work in this month can be divided to two parts, one is objected-based analysis, and another is compiling codes. Although there are some problems, I have succeeded in mapping impervious surface in terms of results and integrated it with Syncarto to achieve an automatic classification.

Extract impervious surface with Multi-source remote sensing data.

My placement has started on June 3rd, and it has been two weeks now. During this time, I have completed some works and made progress.

Before my placement started, I met with Annemarie, my academic supervisor, and she gave me some feedbacks and proposed some questions about my proposal, which lead me to a good point to start my work. At the kick-off meeting with my host supervisor, we discussed some of the questions, and decided to use Orthoimagery from Ayres as data source. The data contains Red, Blue, Green and Near Infrared bands, and has a resolution of 0.5 feet. The study area is focused on Middleton. And impervious surface will be used to identify urban area.
