New layer not showing on map

PhaedraDouglass — Mon, 04 Mar 2024 20:39:43 GMT

I have an online public account and I am trying to add a CSV file to a map, the file does not populate/show up on the map but the data shows in the layers tab. When I add the CSV to the map initially the whole map goes white until I add another layer. There are no error messages, or anything telling me there is an issue, it just doesn't show up. What can I do to make the data show up on the map?

The CSV file I am uploading is pretty simple, location name, longitude, latitude, and some information about the points. I have added similar files before and had no issues.

I just tried this using my public account and a CSV file with approx. 15,000 lat/long locations. Everything worked as expected.

I'd suggest scrutinizing the CSV file a bit more, perhaps there are some hidden characters at the end, etc. I can take very quick look if you email the file to bszukalski@esri.com

Hi Bern,

Thank you, I have sent the file to you.

is the csv data in a different coordinate system than ESRI's web mercator?

If so, often the map will zoom somewhere in limbo and you need to zoom to the layer in the TOC. Even if your basemap and data are the same, if it is NOT the ESRI default, it almost always zooms me to nowhereland when I add data.

The issue was with the formatting in the CSV file, the lat/longs were swapped and there was an odd character in one of the fields.
