XY Conversion from Intergraph NAD_1983_3TM114
I am REALLY hoping someone can help me! I have event data that has address information. This address information is converted through Intergraph into a a "Units of Resolution" measurement (I haven't heard of this before). This is then transformed into XY coordinates in meters for mapping purposes (NAD_ 1983_3TM114) using the following formula:
XTM =((A2+2147483648)/25000)-36000 where A2 is your original coordinate
YTM = ((B2+2147483648)/25000)+5834000 where B2 is your original coordinate
I need a formula that will translate either the Raw X/Y data into DMS or the 3TM X/Y Data into DMS. I'm not sure which way is the better way to go and I don't know what the Units of Resolution are. I have attached a file (RAW XY are in units resolution)
Thanks in advance for ANY help!!
Mapping Center Answer:
Honestly, I've never seen or heard of this and I'm just Googling and not finding anything. Your data need to be in decimal degrees for the XY Events to be processed. Since Intergraph didn't produce that it's beyond my expertise.
Also I just looked at your coordinate list. They don't look geographic to me. The conversion formula for YTM looks flawed. Maybe these are supposed to be UTM coordinates units = meters, but I wouldn't know what zone?
