Part VII: Raster Data & Remote Sensing
Objectives
1. Describe what the raster model is.
2. Explain why rasters are used.
3. Incept situations which rasters would NOT be applicable.
4. List a few types of remote sensing.
5. Know if the types of remote sensing are Passive or Active.
6. List & understand the implications of the four R's.
7. Explain the issues with Remote sensing & why they exist.
Note about R-studio
The homework and instructions are combined into the one rmd file. You will need to download R and R-studio, and then you will be able to open the .rmd. You will need to know where you saved the frogs.txt file, navigate to its location in the files section of R-studio, and set the folder as the working directory.For the submission you can either edit the rmd, change the name and submit it, or you can create a new script, copy and paste the questions and answers into it and submit that, or you can copy and paste the code and output of the code into a word doc.
Format your homework according to the give formatting requirements:
1. The answer must be double spaced, typed, using Times New Roman font (size 12), with one-inch margins on all sides.
2. The response also includes a cover page containing the title of the homework, the course title, the student's name, and the date. The cover page is not included in the required page length.
3. Also include a reference page. The references and Citations should follow APA format. The reference page is not included in the required page length.
