Hi, Using polish-format as input, polylines exceeding MAX_POINTS_IN_LINE in LineSplitterFilter.java, will be splitted in a part which gets the original routeparam values and a splitted part where the routeparam seems to be unset.(e.g Line Typ 0x07 speedclass=2(40km/h) roadclass=0 will be splitted in first part speedclass=2(40km/h) roadclass=0 + second part speedclass=0(5km/h) roadclass=0. OSM-data input instead will be splitted as expected in two parts with the same routeparams. cheers Gert
