So far it’s fully manual, but an optional automatic check might come in the future!

There’s some duplication - but it’s not that easy: Map applications like CoMaps and OsmAnd make their own choices on which types of data from OSM is included in maps and how it’s displayed, and also how the data structure behind the scenes work. This is necessary to create maps that load fast and work well for route calculations etc. So having them compatible between apps is extremely hard.

Vespucci in contrast is a pure OSM editor, so this just gets the ‘raw’ data from OSM for a given region, as it focuses on only editing/adding data to OSM, but not on end-user search, can’t navigate etc.

For that reason it’s unfortunately not likely that a shared format will emerge, as different OSM data users and apps have different needs!

there is https://rudokemper.com/google-maps-places-to-comaps/ for converting the Google Maps takeout to the GPX!

If you have particularly strange routings, feel free to send examples somewhere. As they can be due to OSM errors too, it’s always good to have a look on whether the CoMaps routing is having an issue or if the underlying data can be fixed!

join the matrix room if you haven’t yet, and you’ll find some other map-loving folks who’ll be there!

great name idea! In German the marks you make in books are also called “donkey ears”!

yes, it’s here: https://translate.codeberg.org/projects/comaps/-/pt_BR/

See https://codeberg.org/gedankenstuecke/comaps-map-distributor for an example of setting up a local server to bring it to low connection/bandwidth areas!
