Hi, in the project that I am currently building, i need series of points (nodes) in orderly manner as i transverse along the way from one point to the other. In other words if I am traversing the way, the nodes need to be in the same order in the map data that they are in reality But when i downloaded the OSM data, some of the nodes did not follow a uniform progression on the along the way. |

Not sure if I understood your question correctly. The order in which nodes in the downloaded XML file appear is irrelevant. Each way has |

If I'm clear on what you're asking, that is, you need ways having a series of nodes with timestamps progressing in the direction the way was originally drawn, then the answer is no. That's because a mapper can come along at a later date and add or delete nodes, for example, to improve the accuracy of the way. Also, ways are split and new nodes added for objects like bridges, number of lanes, or changes in maxspeed. There are any number of legitimate reasons that nodes might be added or deleted on ways. I hope this helps answer your question. |
