[Feat] Add JSON to v.what.rast #6024
Description
Adding JSON to v.what.rast should look like:
v.what.rast map=bridges raster=elevation -p format=json
[
{ "category": 4635, "value": 86.85121 },
{ "category": 4648, "value": 87.88326 },
{ "category": 4688, "value": 103.382 },
{ "category": 4709, "value": 67.38786 },
{ "category": 4986, "value": 90.97283 },
{ "category": 4991, "value": 86.55063 },
{ "category": 5027, "value": 84.25636 },
{ "category": 5060, "value": 79.50044 },
{ "category": 5071, "value": 78.73286 },
{ "category": 5089, "value": 85.70364 },
{ "category": 5096, "value": 115.9673 },
{ "category": 5130, "value": 81.05587 },
{ "category": 5150, "value": 92.81293 },
{ "category": 5166, "value": 88.14948 },
{ "category": 5184, "value": 76.42633 }
]I am little unsure if we are using "category" consistently across the tools.
Then there should be option format=csv and separator. By default, no format would be selected resulting in the current output. The header would be written into the CSV with format=csv, if no format is selected it will keep printing it with G_message for backwards compatibility.
