# trips-to-europe
A collection of GPX/GeoJson traces from trips to Europe. They look the best when trains are involved. The best reason to be anti-flying.

## Collecting GPX traces
How to get GPX files. Empty rows I haven't done before but may be apt.
| mode of transport | site(s) | output format |
| --- | --- | --- |
| train | route on and export | gpx |
| car/bus | route on and export | gpx |
| ferry | find ID via query on [OSM](https://www.openstreetmap.org) ([e.g.,](https://www.openstreetmap.org/way/1343490175)), then run query like `way(1343490175); out geom;` on and export | geojson/gpx/kml |
| bike | ??? | ??? |
| plane | ??? | ??? |
| on foot | ??? | ??? |
## Converting filetypes
The `gdal-bin` package can probably do whatever conversion you want. If you're going from gpx, you may need to add `tracks` to the command. Also, the `from`/`to` arguments seem swapped (`to` is first).
```bash
sudo apt install gdal-bin
# convert GEOJSON -> KML
ogr2ogr route.kml route.geojson
# convert GPX -> GEOJSON
ogr2ogr route.geojson route.gpx tracks
```
## Viewing data
View files nicely (as a preview) on:
| filetype | website | notes |
| --- | --- | --- |
| `.gpx` | | |
| `.geojson` | | |
| `.kml` | ??? | |
| other | ??? | |
## Combining GPX traces
Name the traces something nice, that when sorted, is in order.
I don't know how to combine/merge `.gpx` files. I do know how to merge `.geojson` files, so I just turn them into those and merge that.
```bash
# convert to geojson
mkdir geojson
for file in gpx/*; do
bn="${file#*/}"
ogr2ogr "geojson/${bn%*.gpx}.geojson" "${file}" tracks
done
```
…combine geojson
```bash
# combine geojson
endfile="all.geojson"
while read file; do
cat "${file}";
done <<< $(find geojson -type f | sort -n) | jq -c --slurp '{
"type": "FeatureCollection",
"name": "combined",
"features": ([.[] | .features[0]])
}' > "${endfile}"
# remove "messages" and "times" from properties (from brouter train router)
# and remove height coordinate from coordinate strings
cat "${endfile}" \
| jq -c '
.features[].properties |= del(.messages) |
.features[].properties |= del(.times) |
.features[] |= (
if .geometry.type == "MultiLineString" then
.geometry.coordinates |= (.[] |= (.[] |= del(.[2])))
elif .geometry.type == "LineString" then
.geometry.coordinates |= (.[] |= del(.[2]))
else
.
end
)'\
| sponge "${endfile}"
```
combine all geojson files into one:
```bash
files=("2018-08 Paris/all.geojson" "2022-07 interrail/all.geojson" "2023-07 keptp/all.geojson" "2024-12 CCC/all.geojson" "2025-04 blummit/all.geojson")
for file in "${files[@]}"; do
printf '{"key": "%s", "value": ' "${file}"
cat "${file}" | jq -c
printf "}"
done | jq --slurp -c 'from_entries' > all.json
```
