GfsMapProjection

From Gerris

This object remaps the model coordinates using a Lambert conformal conic projection with user-defined parameters. The x-coordinate then becomes the value of the (east positive) longitude in decimal degrees, the y-coordinate becomes the (north positive) latitude in decimal degrees and the z-coordinate becomes the altitude in metres.

The syntax in parameter files is

GfsMapProjection {
  lon = 174
  lat = -41
  scale = 500e3
  angle = 40
  zscale = 250e3
}

with

lon

the longitude of the center of the reference GfsBox.

lat

the latitude of the center of the reference GfsBox.

scale

the reference GfsBox size in metres.

angle

an optional rotation angle in the lon-lat plane (default is zero).

zscale

an optional scaling for the z coordinate (default is scale).
