The CAMS Interactive Atlas Package allows a user to computer contour any
hydrographic quantity on any isosurface in any global projection. It consists
of two parts: a large, and growing, data base which can be easily supplemented
with user-supplied data, and a set of computer software routines that manage
the data, interpolate onto the isosurface, and draw the maps.
The data base presently includes the Levitus Climatological Atlas, IGY
data, GEOSECs, TTO, and many NODC stations, all in a common format. In addition,
the WHO! CTD data set can be easily accessed. This data base will be
supplemented as new data becomes available.
The software routines allow the user to interpolate the data vertically on
to a selected isopleth, such as an isobaric or isopycnal surface, and then
horizontally interpolate the station data onto a regular grid for final contouring.
Land mass areas can be automatically blanked out. The continental
boundaries are drawn in and the contouring done in any one of fifteen projections.
Station locations, cruise tracks, and bottom topography can all be
included. The contour map can be plotted on either a vector plotter or a
raster device, allowing the use of color in the final product.
