nettopologysuite polygon boundary len
<p>i'm very new in topology suite? and have some problem with understanding. I'm trying to get length of the line which the road of some city... line is represented like lon\lat array of gps coords. I convert it to Mercator and then create polygon with buffer, take its boundary length and divide by 2... But the problem is that actual length is less then 1.6 times:( Does anybody can help me with this problem?</p>
