set reference point in lat/lon for dataset in UTM coordinate

[cirrusasf]

Description of the desired feature current mintpy.reference.lalo in the configure file accepts y and x in projected coordinates and mintpy.reference.yx accepts the rows and cols of the data array. Can you provide the new option to define the reference point by accepting latitude/longitude in degree in WRG84?

Thank you @cirrusasf, this feature sounds reasonable and useful. One solution could be: for each geo-coordinate related option, add an accompanying option to specify a different unit from the input native one, e.g. for mintpy.reference.lalo, add the following template option and corresponding handling code:

mintpy.reference.laloUnit = auto  #[none / degree / meter], auto for none (native geo-coordinates)

Contributions are more than welcome.
