Changing Map Units

[KenLucas]

I need to calc degrees minutes seconds formats for latitude & longitude coordinates in a point feature class projected as NAD83 state plane Oklahoma, south, Feet. I received a very helpful answer from Neil Ayres, earlier this week, to my query on how to use the data frame GCS North American 1983 and calc geometry to calc the coordinates for a feature class projected as NAD83 State Plane Oklahoma, feet. Unfortunately, since the decimal degrees option is greyed out for the data frame that is the format the calc geometry tool calcs. How can I calc or change decimal degrees lats and longs to deg min sec format. I've tried, unsuccessfully, doing project to change the fc projection to another that would allow a change to the desired format.

how about Convert Coordinate Notation—Help | ArcGIS for Desktop

As Dan_Patterson says, the Convert Coordinate Notation tool will allow you to add XY in DMS, DM, etc. These are coordinate "notations", ways of describing the lat/long. They cannot actually be used as input into the GIS directly as coordinates, because they are not a number, but a string representation.

This is the first time I've heard of the convert coord not tool. After an hour of online research, before I posted my ques, I'd not found any mention of the tool. I'd still be hung up without Dan and Neil's replies. After several tries here's the procedure that worked for me:

I projected a blank arcmap to GCS North Amer 83 - I added in my point fc, NAD83 Stateplane Ok, feet - I set the tool up as follows:

thank all of you who advised me

Ken, just as a heads up, there are a couple bugs in this tool.

Looks like these are schedules to be fixed in v10.5 (tentative release early next year last I heard)

Rebecca,

Thank you so much for commenting. I've not checked the position of

the coords provided by the notation tool.

2 meters is a problem for me, so I'll check some of the positions

and, if they are off that far, I'll make a note to change them after

the bug is fixed, so the coords don't get truncated as much.

I appreciate you looking out for me,

Ken
