# Wrong UTM zone settings in GPS receiver

I recently made a survey with an rtk GPS in an area within the UTM zone 32 N. Alas, the instrument was set to work on zone 33 N. When I load the points on a map applying the zone 32 projection (EPSG 32632) they are displayed far more west than they should be. Using the 32 N projection instead (EPSG 32633) puts them way east. The coordinates are in easting and northing format (see first three rows of the dataset here below).

Is there a way of converting the GPS readings "from 33 to 32" UTM zones?

``````P_Id Easting    Northing    Hellips.Elev
0   503815.028  5069932.565 214.429
1   497760.019  5080841.423 207.929
2   497747.633  5080748.276 205.616

• What program(s) are you working with? Commented Feb 18, 2022 at 12:18
• If possible, the best would be to output the coordinates in WGS84 and then convert them to UTM. This way, hopefully the conversion will be correctly executed. Commented Feb 19, 2022 at 18:05
• I think you're in trouble. The coordinates you have look perfectly reasonable for 32N--very close to the middle of the zone. If they had been collected in 33N, they should have much larger easting values. Commented Feb 25, 2022 at 3:58
• NGS NCAT software using 32N gives Latitude N45° 46′ 58.59361″ N454658.59361 45.7829426690 Longitude E09° 02′ 56.67953″ E0090256.67953 9.0490776474 Commented Feb 25, 2022 at 3:59
• Using 33N gives Latitude N45° 46′ 58.59361″ N454658.59361 45.7829426690 Longitude E15° 02′ 56.67953″ E0150256.67953 15.0490776474 Commented Feb 25, 2022 at 3:59

• Use python to iterate through the wl and el, calculate the delta x and delta y of each point and create a new point having: `x = wx + (delta_x/2)` and `y = wy + (delta_y/2)`.
