why esri would not use GeoJSON while all others google apple microsoft does

Question

GeoJSON is a fundation format for Web based GIS platform 

 

 

Short answer:   

                                 ESRI can't use GeoJSON 

 

 

Long story:

1). Economically:

GeoJSON is not invented by ESRI, it is invented by another company Mapbox.

To prevent money flow to other company, esri natually allergic to GeoJSON.

ESRI's prefer you to use their EsriJSON instead of GeoJSON

 

 

 

 

2). Technically:

GeoJSON only have 1 coordinate system which is WGS1984.

 

EsriJSON can handle any existing coordinate system

by its spatial reference attribute WKID (well-know-id) 

 

 

 

 

                                      

GeoJSON unit is always degree, 

a number in geojson for example 89.34 

is always means 89.34 degree latitude or longitude

The number 89.34 in EsriJSON could means 

Meter or US-foot or Degree 

or what ever unit depends on coordinate system WKID attribute specified.  

In EsriJSON, if WKID specified is state plan coordinate system, 

then 89.34 will means 89.34 US-foot easting or northing from 

that state plan zone's center reference point.

If your data is in ESRI's format, 

you can't directly use other company's GIS product 

because of formate incompatible. 

This will economically benefit ESRI.

 

 

USGS publish current month earth quake in geojson format, how are you going to look at it?

 

Step 1.

copy this usgs earth quake geojson file path

https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_month.geojson

 

 

 

 

Step 2.

select any layer is fine, does not matter which layer, 

but looking for blue box, all these model can load geojson file on map. 

If your geojson file is remotely a URL link path, select model "url"

otherwise, your geojson file is physically on your hard drive, select model "upload",
