Construct matching time independent one-layer GRIDDED and BOUNDARY files withREAL
variablesLAT
andLON
containing the latitude and longitude at cell centers (consistent with ISO Standard 6709), for a user specified coordinate system and grid. Specifications for this grid may either come from a GRIDDESC file or may be entered interactively. For I/O API 3.2, uses I/O API spheroid manipulation routineSETSPHERE
to determine the geodetic spheroid used for the map projection.For I/O API 3.1 and earlier, and pre-December 25,2017 I/O API 3.2, only Lat-lon, Lambert, UTM, and Albers Equal-Area coordinate systems for interactive input, and boundaries with
NTHIK > 0
are supported. All standard I/O API map projections are supported for grid definition using a GRIDDESC file for I/O API 3.2.You may turn off either output file (
GRIDDED
orBOUNDARY
) by responding "NONE" to the prompt for its logical name.For I/O API Version 3.2, post-December 25,2017: Add output of
REAL*8 (M3DBLE)
