Coordinate Conversion widget in wrong hemisphere

Question

Hi @AlixVezina @Jianxia 
I’m configuring the Coordinate Conversion widget so a user can enter in a set of coordinates, zoom in to that exact location, and add a new feature using the edit widget. I believe I have configured the input so the user enters in coordinates in Degrees Decimal Minutes (DDM) like this: Y°‎ A'N, X°‎ B'W, specifically in the Western hemisphere since the default is Eastern. However, when I paste in a set of coordinates (e.g. coordinates copied from the Coordinates widget) it automatically takes me to the Eastern hemisphere. Am I missing a step in the configuration or is this a bug?

Example: The Coordinates widget gives me this set of coordinates: 37°34.617′ 119°40.667′; I paste this into the Coordinate Conversion widget and get this: 37°‎ 34.617000'N, 119°‎ 40.667000'E

If I were to delete the "E" and replace it with "W", or remove the E and put a "-" in front of the longitude it will zoom to the correct location. I would prefer that the users receive the correct location immediately, though.

Thank you!

Hi @KatieHansen_NIFCAdmin I did some research, and this coordinate conversion widget is built on top of the JS API widget. The behavior you're seeing is by design. In the default coordinate display, each capital letter represents a variable. For DDM, the variables are Y (degrees north/south), A (minutes north/south), N (N/S marker), X (degrees east/west), B (minutes east/west), and E (E/W marker). Each variable will be swapped out by the corresponding value from the actual coordinate for display purposes. So, the variable E will be swapped out with 'E' or 'W' in the displayed coordinate. But W isn't a valid variable, so replacing the E with a W will get rid of the 'E'/'W' hemisphere marker and always show the letter W (as you noticed).

The goal of the coordinate display setting is to add/remove strings to/from the coordinate (like °, ', or the comma), delete sections of the coordinate the user might not be interested in, or move sections of the coordinate around (e.g. showing X, Y instead of Y, X).

The JS API team would be able to help you if you've more questions on this. Have a good weekend, Thanks!

Hi @SubaKrishnan 
Thank you for your message! I am tracking the new "BUG-000163706: Experience Builder Coordinate widget provides the wrong coordinates in Degrees Decimal Minute" regarding this issue. I will use the Coordinate Conversion widget without the Coordinates widget as an input.

I do have another case open related to the conversion widget that addresses the settings of the coordinate input format, but, as is, if I ask my users to input the coordinates in a specific format it will send them to the correct location.

Hi @KatieHansen_NIFCAdmin I'm the Product owner of the coordinate conversion widget. It looks like the issue is with the coordinate widget. I understand your workflow is to input the coordinates in coordinate conversion widget but am wondering the use case for getting coordinates from coordinate widget instead of using the add point feature in coordinate conversion widget?
