However, in the two latest constituency boundary announcements from the Election Commission, a new system of coordinate references seems to have started. Published on March 3 and approved for publication on February 23, the constituencies for the forthcoming municipal election in Yasothon town (เทศบาลเมืองยโสธร) have been changed [Gazette], modifying the boundaries defined in 2004 [Gazette]. And within this announcement, coordinates given as UTM ๐๔๐๗๖๒๙ ๑๗๔๖๘๓๔. Again omitting the obvious zone 48P, and probably still within the Thai Indian 1975 frame. In fact, MGRS is only a different way of writing down an UTM coordinate, the first two digits of the easting and northing each become a letter. Also notable, the UTM coordinates in this announcement have one digit more in both northing and easting, thus an accuracy of 1 meter instead of 10 meter as used in the MGRS coordinates.
And since it is not that many coordinates, I have done the work again to create a simple map out of them, trying to match the boundaries of the constituencies with the boundaries of the municipality as defined in 1994, when the municipality was created [Gazette].
