Hey, here is my report for the project week 15. I worked on the temporal raster algebra. I rewrite the temporal operator analyser to work also with raster functions and implemented the lexical analysis for expressions. Furthermore I added arithmetic operations to the temporal raster algebra for division, multiplication, addition, subtraction and others. Therefore I had to rearrange the command list to work with r.mapcalc expression strings. In the next week I will continue to finish the implementation of these arithmetic operations and add some more raster functions. All problems, that occurred, could be solved.
