Problem loading GeoJSON file on geojson.io

Question

I am newbie in GeoJSON file. I am having difficulty to load my GeoJSON file on geojson.io. Here is my GeoJSON file:

https://gist.github.com/anonymous/0abb8f926977d577b52d.

The source file is from:

http://data.gov.sg/common/search.aspx?cs=1&q=Region+Census2010&a=AVA,HPB,IDA,IPOS,IE,MINDEF,SCDF,SPF,NHB,PUB,SLA,SSC,STB,WDA,URA&da=CPF,CAAS,EDB,EMA,HSA,IRAS,LTA,MPA,MCCY,MOE,SING,MFA,MOH,ICA,SPS,MSF,DOS,MOT,MAS,NYP,NAC,NLB,NPAR,RP,SP,SPIB&c=12,03,02,07,09,04,08,05&dc=01,10,06,11&f=SHP&df=CSV,KML,PGDB,TXT,OTHERS,XLS,XML&page=1

named RegionalCensus2010.

It is a shapefile. I convert the shapefile to GeoJSON using QGIS. I don't have any issue when I am using GeoJSON file from other resources like US government file, but somehow I just can't load my GeoJSON file. I have checked the structure of the file which seems to be correct but I am not sure why I can't load map layer on geojson.io.

Answer 1

Your data seems to be in a CRS which is not WGS84 (i.e. EPSG:4326). Thus, it can not be properly displayed by github gists nor on geojson.io.

Try to re-export the original shapefile from QGIS to geojson , and choose WGS84 EPSG:4326 in the CRS field of the dialog that opens when you right-click the layer in QGIS and choose "save as.."

Answer 2

Initially, I thought it's fine since I can see the shape of the map on QGIS and MapShaper but not geojson.io. But after I tried out the CRS options one by one on GIS. I just figured out I am using the wrong CRS. Nevertheless, thanks for the quick reply.
