I am looking at some old data, and I encountered a data point with a latitude and longitude coordinates in a format that I'm not familiar with. I tried researching some other formats and tried pinpointing the exact location with little luck.

example:

latitude: 484.196.111

longitude: 94.146.944

I am looking to convert such values to a suitable WGS84 format for mapping.

  • Can you add the map or a snapshot of the data? Commented Nov 20, 2018 at 18:54
  • Try to write the numbers with out the dots: 94146944. It can solved it Commented Nov 20, 2018 at 18:55
  • How would you interpret 94146944?

    did you store these pois in excel? just asking because excel likes to be "intelligent" and converts formats without asking; thats where I sometimes get such coordinates from.

I had the same problem once, and writing the number without the dots solved it. Here the steps I used to solved the problem. I choose the "WGS 84 / Pseudo-Mercator" CRS. This values does not exist in the Mercator projection, I choose it because I have no data about regarding the right CRS.

  1. save the numbers without the dots in a "CSV UTF-8 (Comma delimited) file. You can save any number of points that you need.

enter image description here

  1. Upload the file as "Delimited Text Layer".

  1. know you need to be sure that the X and Y fields are matching the latitude and longitude. Also, you need to choose the right CRS. enter image description here

In your case "WGS 84 / Pseudo-Mercator" is not the right CRS, the point layer is nowhere to be found. Know, you need to change the item CRS in the "layers" panel.

enter image description here

Inside this bar you can change the CRS and to see if you got the right CRRS. The red square should overlap the world map, which its CRS is "WGS 84 / Pseudo-Mercator".

enter image description here

Know, if you have any data about the location which that data was created you can try with CRS that related to a country. Historically, there are a lot of CRS that were used by many different countries, so you have a lot of options. If you don't have this info you can always go over the CRS one by one.
