spatialReference

[GianniRossi]

Hello,

I’m totally new to the ESRI world but I would like to become a ESRI user for my company, a software house developing local area maps management.

So my questions are very basic: I’ve come across to a database of points having the following structure:

geometry: {

- rings: [

   - [

       - [

1250201.0937266531,

5720625.987363001

          ],

   .... other elements

         ]

     ],

  - spatialReference: {

       wkid: 102100,

       latestWkid: 3857

    }

}

I would like to know:

1) What is the reference system of the coordinates ?

2) What are the data in the spatialReference brackets ?

Thanks in advance,

Gianni

Hi Bjorn and Xander,

Searching on the internet I found for ETRS89 SRID = 4258 and for WGS84 SRID = 4326 for , so I tried to use the ArcGIS GeometryService with the following data:

Input Spatial Reference:     4258

Output Spatial Reference:   4326

Geometries:   {url:"http://www.corrmap.com/download/PF_TN.txt"}

But I get this error:

JSON syntax error - expected JSONStartOfArray, got JSONEndOfObject

I checked my PF_TN.txt file and it seems having exactly the same format of that used by Bjorn:

What am I doing wrong?

Thanks in advance,

Gianni
