+## Question 1
+
+![](maps/ndvi_ndwi.png)
+
+## Question 2
+
+![](maps/surface_temp_b10.png)
+![](maps/surface_temp_b11.png)
+
+The original Raster file included values from -125 C which are not realistic in germany. Also Maximum temperatures from 44 degrees are not common, but could be explainable through realy heat conductiv material on very small areas.
+
+Between Water bodies and land bodies. and also the north and south of the area.
+
+## Question 3
+
+![](maps/true_color.png)
+![](maps/false_color.png)
+
+The main differences of the map are the Bands and their display of it. For example the true color composite consists of band 2,3 and 4 in the order of RGB as 4,3,2. The false color composite consists of band 3,4 and 5 in the order ich which Vegetation is the most visible (5,4,3). 
+
+## Question 4
+
+![](maps/ndvi_chiloe_2013.png)
+![](maps/ndvi_chiloe_2024.png)
+
+I choose this study area because i was on this island Chiloe in Chile for a bit and noticed a lot of National parks and vegeation there and i wanted to know how this changed in these past years. These two images show difference in NDVI between 2013 and 2024 of the island Chiloe in Chile and surroundings. I chose NDVI as it shows the difference in vegetation very well.

+## Question 1
+

+
+## Question 2
+
+![](maps/diff_ndwi.png)
+
+![](plots/diff_hist.png)
+
+Landsat 8 uses broader NIR and Green bands with a 30m resolution, while Sentinel-2 uses narrower bands with a 10m resolution. Differences in atmospheric correction methods and time of capture could also be factors.
+
+## Question 3
+
+For the third question i choose the Chacao Channel as it is also a very interesting region because of its national parks agriculture and abundance of waterbodies. 
+
+![](maps/ndvi2.png)
+
+![](maps/ndwi2.png)
+
+Here the symbology was reduced to 0-0.2 because the calculations resultet in a peak around this area and near to zero values till 1. Which doenst make much sense because the area has a lot of waterbodies. I couldnt find and error.
