How to get data, from [weeknote 2024/29](https://weeknotes.alifeee.co.uk/2024-29/).

```text

Here is the River Sheaf on Open Street Map (OSM)

It is made up of a series of "ways", which are lines with coordinates, added by normal people.

I used Overpass Turbo () to export a [`geoJSON`](https://geojson.org/) file for the River Sheaf (i.e., with `relation(11890887); out geom;`)

to crop:

sudo apt install gdal-bin

ogr2ogr -clipsrc -1.47927 53.34511 -1.49590 53.35812 export2.geojson export.geojson

```

## combine geojson

```bash

endfile="all-river-walks.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}"

```
