Données polygonales multiples en mappant des formes individuelles en utilisant R ou Ironpython [N'utilisant ni QGIS ni aucun outil]

Question

J'avais une API qui donnait une sortie comme JSON [geoJson] en ce que j'avais des données multipolygones. J'ai besoin de convertir ces données multi polygones en une forme que nous pouvons stocker sous la forme d'une table et ensuite l'utiliser sur le graphique Spotfire Map.

données

exemple: `

      "type": "MultiPolygon",

Answer 1

On suppose shp est votre exemple stocké comme une variable de caractères:

library(sf) 
x <- read_sf(shp) 
plot(x) 

Cela ne convertit pas à une table, mais il lit le texte de geojson, le convertit en une caractéristique simple, et vous permet ensuite de le tracer avec la méthode propre à l'objet.
