**1**hi,

i have a problem with "Hotine Oblique Mercator B" seems that is insensitive at AZIMUTH ANGLE parameter.

For replicating the problem try this, using coordinate converter:

Input Coordinate:

X=392937.9206

Y=5818466.7383

Input coordinate system:

EPSG 25833

Output coordinate system:

HOTINE OBLIQUE MERCATOR B

DATUM: WGS84

PLANAR UNITS: METERS

CENTER SCALE FACTOR: 1

AZIMUT ANGLE:

AMIUTH PT 13.421146

ORIGIN LATITUDE 52.504883

FALSE EAST 1000

FALSE NORTH 2000

AZIMUT ANGLE:

**XXXXXXXX**AMIUTH PT 13.421146

ORIGIN LATITUDE 52.504883

FALSE EAST 1000

FALSE NORTH 2000

**Global Mapper tested on v16, v17, v18, v19**

**XXXXXXXX = 5 then X=1097.815 and Y=2102.188**

**XXXXXXXX = 30 then X=1097.815 and Y=2102.188**

**XXXXXXXX = 45 then X=1097.815 and Y=2102.188**

**XXXXXXXX = 60 then X=1097.815 and Y=2102.188**

**XXXXXXXX = -45 then X=1097.815 and Y=2102.188**

with proj.4

**XXXXXXXX = 5 then X=1087.6814 and Y=2109.5443**

**XXXXXXXX = 30 then X=1033.1709 and Y=2136.3366**

**XXXXXXXX = 45 then X=996.7541 and Y=2140.2763**

**XXXXXXXX = 60 then X=960.5585 and Y=2134.6564**

**XXXXXXXX = -45 then X=1140.2763 and Y=2003.2459**

Many Thanks for attention

Mario
