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.
