aloha, i use a buffer around my polylines to select nearby points on another table. the buffers i use however are somwhat smaller than a lot of the examples i've come across where they are calculating stuff on a statewide basis. my buffers are around a Bus Route drawn as a polyline, to pick up all bus stops within a given distance, however it seems to give erratic results. on some lines if i put a buffer of 50 metres in, it buffers a few seemingly random parts of the polyline, leaving "buffer bubbles" along the route, but if i increase the buffer to 100-200 metres then most of the time it werks. any ideas? ash
