Longitude & Latitude format

JP Guilbault Jul 28, 2016 2:56 PM

Hi,

I'm quite a beginner with Tableau software and I'm trying to visualize some data obtained on my city open data website and the longitude and latitude are in formats that cannot be recognize by Tableau Public.

Ex.: lat 298588.54 and long 5040384.54

So I was wondering if it was possible to convert these numbers in an understandable format in order to put them on a map? Thanks.

And sorry for my English, it's not my native language!

Can you provide a link to the source data or a preview of the source data? That seems like an unusual way to express a lat/lon to me...

Those aren't lat/long combinations in that file, they look like an X/Y co-ordinate to me. It does appear as if you can download shape files off that same page which you would traditionally use in a GIS tool.
How you get that X/Y converted to a Lat Long for Tableau is a little beyond me unfortunately.
