 - Convert a Shapefile into a GeoPackage:
 
 `ogr2ogr -f GPKG {{path/to/output}}.gpkg {{path/to/input}}.shp`
 
+- Reduce a GeoJSON to features matching a condition:
+
+`ogr2ogr -where '{{myProperty > 42}}' -f {{GeoJSON}} {{path/to/output.geojson}} {{path/to/input.geojson}}`
+
 - Change coordinate reference system of a GeoPackage from `EPSG:4326` to `EPSG:3857`:
 
 `ogr2ogr -s_srs {{EPSG:4326}} -t_srs {{EPSG:3857}} -f GPKG {{path/to/output}}.gpkg {{path/to/input}}.gpkg`
