Rectified Skewed Orthomorphic

Description

Rectified skewed orthomorphic (RSO)—this projection is provided with two options in ArcInfo Workstation for coordinate systems in Malaya and Borneo and is similar to the Hotine Oblique Mercator.

Projection method

Oblique cylindrical projection. A line of true scale is drawn at an angle to the central meridian.

Line of contact

A single, oblique, great-circle line.

Linear graticules

Two meridians 180° apart.

Properties

Shape

Conformal—local shapes are true.

Area

Increases with distance from the central line.

Direction

Local angles are correct.

Distance

True along the chosen center line.

Limitations

Its use is limited in ArcInfo Workstation to those areas of Borneo and Malaya for which the projection was developed.

In the ArcGIS Desktop applications, distortion increases rapidly away from the central line.

Uses and applications

Used for coordinate systems in Malaya and Borneo.
