Oblique Mercator¶
Parameters¶
Central point and azimuth method¶
-
+alpha
=<value>
¶ Azimuth of centerline clockwise from north at the center point of the line. If
+gamma
is not given then+alpha
determines the value of+gamma
.
-
+gamma
=<value>
¶ Azimuth of centerline clockwise from north of the rectified bearing of centre line. If
+alpha
is not given, then+gamma
is used to determine+alpha
.
-
+lonc
=<value>
¶ Longitude of the central point.
-
+lat_0
=<value>
¶ Latitude of the central point.
Two point method¶
-
+lon_1
=<value>
¶ Longitude of first point.
-
+lat_1
=<value>
¶ Latitude of first point.
-
+lon_2
=<value>
¶ Longitude of second point.
-
+lat_2
=<value>
¶ Latitude of second point.
Optional¶
-
+no_rot
¶

-
+no_off
¶

-
+k_0
=<value>
¶ Scale factor. Determines scale factor used in the projection.
Defaults to 1.0.
