No real docs. There are some tweaks on the edges with regards to renaming protocol buffer message names and field names. Mostly search&replace. Field numbers may have changed, so the earliest files are not compatible. There are a few semantic differences that affect parsing. Offset numbers are now in the format that let the grid in the binary file be aligned with a grid in a dataset for datasets with a regular grid, such as isohypsis files. The other notable change is I have have extended DenseNodes to support tags and so have removed the former Node. This has resulted in '0' no longer being available for use as a string identifier. It is being used as a delimiter. In a week or two, depending on feedback and any resulting changes, I will upload reference files to github. If you update the reader, I would appreciate a copy, Thanks, Scott _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
