thanks for the pointer!
i managed to extract the coordinates out of the 2.5 MB geojson trip file, that got micropubed to my site. that’s still around 500 KB of coordinates. i think simplifying those coordinates myself would be a little tough for my spatial and algorithmic skills. i’d be happy if compass micropubed not only the coordinates, but also a map image, with predefined dimensions. while it’s nice to get all the data pumped over to my site, i’d be happy with just an image of the trip and the trip characteristics like distance, start and end point.
just getting the trip characteristics and a map image after finishing a trip would probably be sufficient for most users that have weak calculating skills like myself.
