Hi I known this sound like a strange question, but is it possible to create a buffer around 1/2 of geomtry objectt.
If I choose to buffer round a stright line, I get a geomtry that looks like a sausage, if I buffer round a point, I get a geomtry that looks like a circle. What I would like to do is buffer round only half an object, in the case of a point I would like to get a semi circle, buffer round a line, 1/2 a sausage! Is this possible, any suggestions ? In the simultation that I am modeling, the data point/line describe a starting point and I need to ensure that its possible for traffic to leave the starting point on one side.
