You can use the CoordinateExtractor to get coordinates from a line and store them in attributes. Use two of them, with the mode set to Specify Coordinate and the indexes to 0 (first coordinate) and -1 (last coordinate).

Calculating the length of a line can be done with the LengthCalculator.

I don't think GeoPDF maintains an internal line id, but you can use a Counter to create your own.

Thanks for reply but after i read adobe geospatial pdf , there is a point that has id close to each line

i would like to extract the id number for each line . Could u give me an idea ,how to extract it ?



You can try the NeighborFinder, with the caveat that the closest point to a line may not be the correct one.
