Linear features are based on a series of x,y <br />coordinates that are connected to form a line. Areas are also <br />represented by a series of x,y coordinates with the starting and ending <br />coordinate identical, resulting in a closed shape. <br /> <br />"','~'~ <br /> <br />.. .c'-'~' <br />li- <br /> <br />"';'~l~ <br /> <br />Part 3: The basic components of vector data <br /> <br />The points, lines and areas or polygons in vector data represent different types of features, <br /> <br />... r-'I~E,"'rr>p.i1r.':,"""" <br /> <br />. 1.',"~lJI"I,j"l"":'Jtl':i'\1...in( <br />.- ;"..t.;I-.l~'1Ij!
