Supermorecado

通过额外的命令扩展morecantile的功能。

文档： https://developmentseed.org/supermorecado/

源代码： https://github.com/developmentseed/supermorecado

supermorecado类似于supermercado，但支持其他TileMatrixSet网格。

安装

$ python -m pip install -U pip
$ python -m pip install supermorecado

# Or install from source:

$ python -m pip install -U pip
$ python -m pip install git+https://github.com/developmentseed/supermorecado.git

用法

supermorecado --help
Usage: supermorecado [OPTIONS] COMMAND [ARGS]...

  Command line interface for the Supermorecado Python package.

Options:
  --help  Show this message and exit.

Commands:
  burn     Burn a stream of GeoJSONs into a output stream of the tiles they intersect for a given zoom.
  edges    For a stream of [<x>, <y>, <z>] tiles, return only those tiles that are on the edge.
  heatmap  Creates a vector `heatmap` of tile densities.
  union    Returns the unioned shape of a stream of [<x>, <y>, <z>] tiles in GeoJSON.

supermorecado burn

<{geojson} stream> | supermorecado burn <zoom> --identifier {tms Identifier} | <[x, y, z] stream>

接受GeoJSON输入流，并返回给定缩放级别的相交[x, y, z]流。

使用默认TMS（WebMercatorQuad）

cat tests/fixtures/france.geojson | supermorecado burn 9 | morecantile shapes | fio collect | geojsonio

使用其他TMS（例如WGS1984Quad）

cat tests/fixtures/france.geojson | supermorecado burn 6 --identifier WGS1984Quad | morecantile shapes --identifier WGS1984Quad | fio collect | geojsonio

supermorecado edges

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

输出代表输入流[x, y, z]的边缘瓦片的[x, y, z]流。边缘瓦片 = 任何与不存在瓦片直接相邻或与空瓦片对角相邻的瓦片。

cat tests/fixtures/france.geojson | supermorecado burn 9 | supermorecado edges | morecantile shapes | fio collect | geojsonio

supermorecado union

<[x, y, z] stream> | supermorecado union --identifier {tms Identifier} | <{geojson} stream>

从输入流 [x, y, z] 中输出合并的 GeoJSON 流。类似于 morecantile shapes，但以整体足迹而不是每个瓦片的单个形状的形式。

使用默认TMS（WebMercatorQuad）

cat tests/fixtures/france.geojson | supermorecado burn 9 | supermorecado union | fio collect | geojsonio

使用其他TMS（例如WGS1984Quad）

cat tests/fixtures/france.geojson | supermorecado burn 6 --identifier WGS1984Quad |  supermorecado union --identifier WGS1984Quad | fio collect | geojsonio

supermorecado 热图

<[x, y, z] stream> | supermorecado heatmap --identifier {tms Identifier} | <{geojson} stream>

从输入流 [x, y, z] 中输出热图 GeoJSON 流。

使用默认TMS（WebMercatorQuad）

cat tests/fixtures/heatmap.txt| supermorecado heatmap | fio collect | geojsonio

使用其他TMS（例如WGS1984Quad）

# create a list of tiles
cat tests/fixtures/france.geojson | supermorecado burn 6 --identifier WGS1984Quad > france_wgs84_z6.txt
# randomly append more tiles
for run in {1..10}; do cat france_wgs84_z6.txt | sort -R | head -n 2 >> france_wgs84_z6.txt; done

cat france_wgs84_z6.txt |  supermorecado heatmap --identifier WGS1984Quad | fio collect | geojsonio

API 迁移

supermorecado 实际上与 supermercado 非常相似（它重用了大部分代码），但增加了来自 morecantile 的多个 TMS 支持。

features = [
    {
        "geometry": {
            "coordinates": [
                [-127.97, 49.15],
                [-101.95, -8.41],
                [-43.24, -32.84],
                [37.62, -25.17],
                [71.72, -7.01],
                [107.23, 48.69],
            ],
            "type": "LineString",
        },
        "properties": {},

    },
]

# supermercado
from supermercado import burntiles, uniontiles

tiles = burntiles.burn(features)
u_tiles = uniontiles.union(features)

# supermorecado
import morecantile
from supermorecado import burnTiles, unionTiles

tms = morecantile.tms.get("WebMercatorQuad")

burntiles = burnTiles(tms=tms)
tiles = burntiles.burn(features)

uniontiles = unionTiles(tms=tms)
u_tiles = uniontiles.burn(features)
