Dear Expert,

I trying to create a PoC on GeoMap Design Studio application.

I have generated the CSV file to create a locale PoC fields avaible NAME and REVENUE.

  • GeoJSON:http://eric.clst.org/Stuff/USGeoJSON downloaded and saved on the design studio application repository folder
  • GeoMap Layer have been linked to the Datasource
  • Custom GeoJSON File link to the GeoJSON file on the repository
  • DS with one measure REVENUE and one row NAME
  • GeoJSON file contain the following fields : { "GEO_ID": "0500000US01029", "STATE": "01", "COUNTY": "029", "NAME": "Cleburne", "LSAD": "County", "CENSUSAREA": 560.100000 }
  • The field NAME in the datasource contain values like Cleburne ...

Issue :

  • I am not able to map the field GeoJSON Mapping Properties with the Row field on my datasource.
  • This fields is blank, no values available on the match box.

Do you know the reason of this issue ? how could I solved it ?

Thanks for your help.

Hi,

When you use GeoJSON in a GeoMap, data is plotted on the map if an element name in the data source matches with the name on the GeoJSON file. In the example below, I have plotted the US states. In my GeoJSON file, I must have a field that contains the states names with proper spellings(in my case this is "NAME"). On the additional properties, choose the same field name that was present on the GeoJSON file("NAME"). This field name corresponds to the one in your data. In your case, if the field name is not available, there might be a problem with your GeoJSON file.

If all these are perfectly selected, my output looks like this.

Let me know your feedback.

Thanks

Suriya

Dear Suriya,

Thanks a lot for your information.

Now GeoJSON Mapping Property : display GEO_ID.

I used basemap URL : http://tile.openstreetmap.org/{LOD}/{X}/{Y}.png

My issue is that the values are not displayed on the map.

Did some one already faced this issue ? Any proposal to correct it ?

My data source is an excel file, the charts display the correct values, but still have issues with the GeoMap values.

Thanks for your help.
