UTM to decimal Degree conversion of Coordinates

mlo1 — Wed, 11 Oct 2023 10:55:50 GMT

Hello,

are there any JMP/JSL scripts around to transform UTM to decimal degree coordinates?

Could only find the wishlist entry.

Thank you

Hi @mlo1 ,

How would you prefer the conversion to work?

A column dialog box to identify the various UTM variable names

UTM column selection dialog

and then an output table with latitude and longitude coordinates

UTM to latitude and longitude coordinates

Would you need to go in the other direction? What Geodatum's would need to be supported? WGS84?

cheers,

Stan

Hello Stan,

Accidentially I pressed the solved button.

I am not an expert on Geo data and still with JMP17.2 in case there are changes in JMP18
I am just using it from time to time for visualisation of election data.

While the federal goverment is providing the election districts in decimal degree it is easy to get the maps in JMP.

The states are using different geo data format as shown e.g. for Hessen and Bavaria in the attached picture.

May be the *.prj Information can be used for convertion into decimal degree which is used by JMP.

I attached the three different map data.

Best regards

Mirko

This looks amazing, what it the Add-in or the way to acces this dialogue box?

Hi @SpendingHamster
It's been a while since I wrote the first pass of the code.
Let me know if you would be ok with a basic workflow as shown above with the basic steps:

Open input file
Verify inputs / error checking
Assign input columns to roles
Output a JMP table with derived latitude and longitude based user inputs

If so, I'll put something together and publish it to the marketplace.

cheers,

Stan

Yes, that would be great. however the data I have only has the UTM numbers (Easting and Northing) using , would that still be feasable with the proposed workflow?

@SpendingHamster
Yes I think I could make it work with a limited number of options.

cheers,
