Unformatted text preview: display the maps, and has a tool for measuring the length of a line. Create two graphics. First, use line weight, color, pattern or any other means to display one map with all of the levels of generalization shown. You will find that the challenge is that the lines are all on top of each other, and so are hard to distinguish. Write: Which generalization algorithm you used? How it is different from the other types of algorithms provided? Note: Use minimum 3 levels of generalization other than the original (100% retained) Second, create in Excel or any other package you choose an ( x,y ) plot of the number of points (or % generalization) on the x axis and the line length on the y axis. Why does the line length not increase in direct proportion to the detail?...
