Understanding GeoJSON data

GeoJSON files are a standard way of storing GIS data

These contain not only the coordinates but also the attribute data.

These files have a key: value based hierarchial data structure

You may think of these keys as variable names and values as the dara.

In computer science terminology, these are Objects.

GeoJSON follows a hierarchical organizational pattern for storing data.

At top level, GeoJSON objects have a “Type” : “FeaturesCollection” property and a “Features” property whose value is an array of objects. Each child object of this has

  • “type” = “feature”,
  • “geometry” = containes the GIS Coordinate data
  • “properties” = contains the attribute data – Name, address, contact, facilities, serivices, whjatever catches your fancy !

An example is below

{ "type": "FeatureCollection", "features": [ { "type":"Feature", "properties":{"stname":"Ladakh", "stcode11":"37", "Zone":1},
