◆ G__json()

char* G__json ( void )

This function generates actinia JSON process chain building blocks from the command line arguments that can be used in the actinia processing API.

The following commands will create according JSON output:

r.slope.aspect elevation="elevation@https://storage.googleapis.com/graas-geodata/elev_ned_30m.tif" slope="slope+GTiff" aspect="aspect+GTiff" –json

{ "module": "r.slope.aspect", "id": "r.slope.aspect_1804289383", "inputs":[ {"import_descr": {"source":"https://storage.googleapis.com/graas-geodata/elev_ned_30m.tif", "type":"raster"}, "param": "elevation", "value": "elevation"}, {"param": "format", "value": "degrees"}, {"param": "precision", "value": "FCELL"}, {"param": "zscale", "value": "1.0"}, {"param": "min_slope", "value": "0.0"} ], "outputs":[ {"export": {"format":"GTiff", "type":"raster"}, "param": "slope", "value": "slope"}, {"export": {"format":"GTiff", "type":"raster"}, "param": "aspect", "value": "aspect"} ] }

v.out.ascii input="hospitals@PERMANENT" output="myfile+TXT" –json

{ "module": "v.out.ascii", "id": "v.out.ascii_1804289383", "inputs":[ {"param": "input", "value": "hospitals@PERMANENT"}, {"param": "layer", "value": "1"}, {"param": "type", "value": "point,line,boundary,centroid,area,face,kernel"}, {"param": "format", "value": "point"}, {"param": "separator", "value": "pipe"}, {"param": "precision", "value": "8"} ], "outputs":[ {"export": {"format":"TXT", "type":"file"}, "param": "output", "value": "$file::myfile"} ] }

v.info map="hospitals@PERMANENT" -c –json

{ "module": "v.info", "id": "v.info_1804289383", "flags":"c", "inputs":[ {"param": "map", "value": "hospitals@PERMANENT"}, {"param": "layer", "value": "1"} ] }

A process chain has the following form
