GPX Favorites merge

This tool merges multiple GPX files with favourites data with dedupliucation using an intermediate CSV file allowing modification.

I use this tool to synchronize the favourites.gpx files of multiple OSMAnd installations. The tools is only tested with files from OSMAnd.

Usage

To merge multiple files into one:

./merge.py gpx2csv in1.gpx in2.gpx data.csv categories.json

This results in two files:

data.csv: You can now edit this file with your favorite editor (text/spreadsheet programs) to spot and remove any similar but not exact duplicate entries. The file is sorted by the average of latitude and longitude.
categories.json: Contains the mapping of categories (also: types) and colors.

Then you can generate the GPX file:

./merge.py csv2gpx data.csv categories.json output.gpx
