Buffering on vector data. a. Download three (3) vector files for
points, lines, and polygons. Display each vector file without any
other details (such as background image, more than one type of data
layer, etc.). Produce three screen views of three types of vector
data and paste them under the answer to Question 3.a. (15 marks) b.
Using the three vector files you have created in section 3. a,
perform any three of the following buffering types. 1. fixed-width
buffering (FWB), 2. multi-ring buffering (MRB), 3. one-sided
buffering (OSB), 4. buffering by percentage (BBP) and 5.
multi-distance buffering (MDB). Vector file Your selection of
buffering marks Point 15 Line 15 polygon 15 Add three GIS-screen
images with buffering width (or measurement) details. Do not use
background images. You will be required to show both the data layer
and buffer layer in each GIS-screen image. Zoom the image for
clarity, if required. The above table is a guideline to select the
buffering type. (45 marks) Notes: • Answer each part of the
question separately • For part (a) submit a separate and clear
GIS-screen image for each point, line & polygon. • For part (b)
submit a separate & clear GIS-screen image for each buffer type
with buffering details (i.e., buffering measurements). • Do not use
a background image and/or other data layers with the GIS-screen
images in parts (a) and (b). Expect a loss of marks if you did.
