In the simple cylindrical projection [SNYDER1987], parallels
of latitude and meridians of longitude are straight lines that
intersect one another at right angles.
Images in this projection are centered on the equator. Map
resolution is constant throughout the image, thus increasing
distortion away from the poles.
The transformation from latitude and longitude (LAT, LON) in
degrees to LINE and SAMPLE is given by the following equations.
SCALE = MAP_RESOLUTION
SAMPLE = SAMPLE_PROJECTION_OFFSET+SCALE*(LON-CENTER_LONGITUDE)+1
LINE = LINE_PROJECTION_OFFSET-SCALE*(LAT-CENTER_LATITUDE)+1
In the above definitions, integral values of LINE and SAMPLE
correspond to the center of a pixel, and the top left image
pixel has LINE=1 and SAMPLE=1. LAT and LON are the latitude and
longitude of a given spot on the surface in degrees.
LINE_PROJECTION_OFFSET
is the image line number minus one on which the map projection
origin occurs. The map projection origin is the intersection
of the equator and the projection longitude CENTER_LONGITUDE.
SAMPLE_PROJECTION_OFFSET
is the sample number minus one on which the map projection
origin occurs.
CENTER_LATITUDE
is the value of the projection latitude in degrees, which is
typically the latitude that passes through the center of the
projection.
CENTER_LONGITUDE
is the value of the projection longitude in degrees, which is
typically the longitude that passes through the center of the
projection.
MAP_RESOLUTION
is the number of pixels per degree at the projection origin.
For these products, Jupiter System 3 longitude and planetographic
latitude are used. The prime meridian is defined per Archinal et al,
'Report of the IAU Working Group on Cartographic Coordinates
and Rotational Elements: 2009 [ARCHINAL2010].'
