supermercado burn

<{geojson} stream> | supermercado burn <zoom> | <[x, y, z] stream>

Takes an input stream of GeoJSON and returns a stream of intersecting [x, y, z]s for a given zoom.

cat data/ellada.geojson | supermercado burn 10 | mercantile shapes | fio collect

supermercado edges

<[x, y, z] stream> | supermercado edges | <[x, y, z] stream>

Outputs a stream of [x, y, z]s representing the edge tiles of an input stream of [x, y, z]s. Edge tile = any tile that is either directly adjacent to a tile that does not exist, or diagonal to an empty tile.

cat data/ellada.geojson | supermercado burn 10 | supermercado edges | mercantile shapes | fio collect | geojsonio

supermercado union

<[x, y, z] stream> | supermercado union | <{geojson} stream>

Outputs a stream of unioned GeoJSON from an input stream of [x, y, z]s. Like mercantile shapes but as an overall footprint instead of individual shapes for each tile.

cat data/ellada.geojson | supermercado burn 10 | supermercado union | fio collect | geojsonio
