## H.1 Question 1

• Read the MOD13A3_2000_2019.tif raster to a multi-band raster object. This raster is a series of NDVI images from southern Israel. The date each layer refers to is recorded in the corresponding MOD13A3_2000_2019_dates.csv file.
• Calculate a 12-band raster that will contain the average NDVI per pixel (excluding NA) for each month. The first band will contain the maximal values per pixel in all images taken in January, the second band will contain the maximal values per pixel in all images taken in February, and so on. Use corresponding the MOD13A3_2000_2019_dates.csv table to determine the layers corresponding to each month.
• Plot the resulting raster as shown in Figure H.1 (including month names). Use breaks="equal" for equal color breaks.
• Remember: you cannot use the raster package in your solution! (see Section B.5.5.)

## H.2 Question 2

• Calculate a line that goes through all of the meteorological stations in rainfall.csv, according to annual rainfall order. (The line starts from the station that has the smallest annual rainfall, and ends in the station that has the largest annual rainfall.)
• Print the resulting line length, in $$km$$.
• Plot (Figure H.2):
• The line, in "lightgrey"
• The station locations, as circles, in "darkgrey"
• Text labels with the names of the stations that have the lowest and highest amount of annual rainfall, in "red"
