Definition

A PROJECTION of the cylindrical type, being in principle equivalent to the regular MERCATOR PROJEC­TION turned (transversed) 90° in AZIMUTH. In this PROJEC­TION, the CENTRAL MERIDIAN is represented by a straight line, corresponding to the line which represents the EQUATOR on the regular MERCA­TOR PROJECTION. Neither the GEOGRAPHICAL MERIDI­ANS, except the CENTRAL MERIDIAN, nor the GEODETIC PARAL­LELS, except the EQUATOR (if shown), are repre­sented by straight lines. It is a CONFORMAL PROJEC­TION. Also called transverse cylindrical orthomorphic projection.
