    Why SSRS Map visual is not recognising snowflake spatial data?

    Hi, thanks for the interesting video. Out of curiosity, have you ever tried importing ONS geoJSON data into snowflake? I was using your video as a guide but I'm getting a ton of errors.

      I haven’t but happy to take a look if you’re able to share the data set

      Ok I got it to work in the end. Your main problem is the file size I believe. It was 1.6GB downloaded for me. When I tried to copy it into Snowflake I got a maximum file size exceed error.
      When I pulled a single JSON record out as a test I was able to load it directly into a geography column in the table without issue.
      No doubt people out there may have neat workarounds, as such I'll let others chime in.
