Questions:
1. The scale and orientation of the supplied satellite images.
2. Features in the Preserve area as captured in the imagery.
To identify the features in the Preserve Area, I picked the image which is generated from the data [image11_2016_09_06.csv]. It has no sensor artifacts at all.
Band combinations(B4, B3, B2) are mapped to the RGB image channels to create the false-color image as below.
Band combinations(B5, B4, B2) are mapped to the RGB image channels to create the false-color image as below:
With the NDVI and RVI Value, we can identify the different vegetation.
- Cluster 1: Common vegetation.
- Cluster 2: Road/Newly Land.
- Cluster 3: Healthy Plant which has absorbed the red light strongly.
- Cluster 4: Waterbody.
- Cluster 5: Clouds.
3. Features that change over time in these images.
