In the simple cylindrical projection, 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_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
number of pixels per degree at the projection origin."
