supermercado burn

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

接受GeoJSON输入流，并返回给定缩放级别下相交的[x, y, z]流。

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

supermercado edges

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

输出表示输入流中[x, y, z]边界的[x, y, z]流。边界瓦片是指与不存在瓦片直接相邻或与空瓦片对角相邻的任何瓦片。

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

supermercado union

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

输出从输入流中[x, y, z]的并集GeoJSON。类似于mercantile shapes，但作为整体足迹而不是每个瓦片的单独形状。

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

疯狂一点

cat data/ellada.geojson | supermercado burn 12 | supermercado edges | supermercado union | fio collect | geojsonio
