Documentation: developmentseed.org/supermorecado/

Source Code: developmentseed/supermorecado

---

supermorecado is like supermercado, but with support for other TileMatrixSet grids.

Install

$ 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

Usage

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>

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

Using default TMS (WebMercatorQuad)

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

Using other TMS (e.g 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>

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 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>

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

Using default TMS (WebMercatorQuad)

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

Using other TMS (e.g WGS1984Quad)

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

supermorecado heatmap

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

Outputs a stream of heatmap GeoJSON from an input stream of [x, y, z]s.

Using default TMS (WebMercatorQuad)

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

Using other TMS (e.g 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 migration

supermorecado is really similar to supermercado (it reuse most of the code) but with the addition of multiple TMS support from morecantile.
