The polyline shapefiles for (1) RAS centerlines and (2) RAS cross-sections have multiple geometries (e.g., line strings) for a single river reach or cross-section. They can be organized/sorted by their HYDRAID (for river) or STREAMSTN (for xs). We want to get the coordinates for each river reach and cross-section and they need to be in the correct order otherwise the polyline connection will be incorrect.

The multi-part geometries will either need to be merged based on the HDYRAID or STREAMSTN. Then the coordinates of the line can be saved. OR they can be kept as multi-part geom and the coords can be read for each (e.g., for loop) and saved in a list/array.
