Hello, I have this output in the global attributes of a NetCDF, seemingly originating with USGS and a program called "GEOGRID" - see print below. Does anyone happen to know what MAP_PROJ = 6 and GRIDTYPE = "C" stands for?
The CEN_LAT/CEN_LON are sensible but TRUELAT1/TRUELAT2 look like filler, but maybe they are recorded badly asit looks like an LCC form to me. Appreciate any pointers. Thanks! Cheers, Mike. // global attributes: :TITLE = "OUTPUT FROM GEOGRID V3.2.1" ; :SIMULATION_START_DATE = "0000-00-00_00:00:00" ; :WEST-EAST_GRID_DIMENSION = 216 ; :SOUTH-NORTH_GRID_DIMENSION = 145 ; :BOTTOM-TOP_GRID_DIMENSION = 0 ; :WEST-EAST_PATCH_START_UNSTAG = 1 ; :WEST-EAST_PATCH_END_UNSTAG = 215 ; :WEST-EAST_PATCH_START_STAG = 1 ; :WEST-EAST_PATCH_END_STAG = 216 ; :SOUTH-NORTH_PATCH_START_UNSTAG = 1 ; :SOUTH-NORTH_PATCH_END_UNSTAG = 144 ; :SOUTH-NORTH_PATCH_START_STAG = 1 ; :SOUTH-NORTH_PATCH_END_STAG = 145 ; :GRIDTYPE = "C" ; :DX = 48918.09f ; :DY = 48918.09f ; :DYN_OPT = 2 ; :CEN_LAT = -24.26f ; :CEN_LON = 147.63f ; :TRUELAT1 = 1.e+20f ; :TRUELAT2 = 1.e+20f ; :MOAD_CEN_LAT = -24.26f ; :STAND_LON = 32.37f ; :POLE_LAT = 60.31f ; :POLE_LON = 321.38f ; :corner_lats = -43.18129f, 14.5788f, 14.57882f, -43.18126f, -43.08284f, 14.64489f, 14.64489f, -43.08282f, -43.37204f, 14.78275f, 14.78277f, -43.37201f, -43.27347f, 14.84871f, 14.84871f, -43.27346f ; :corner_lons = 83.15466f, 110.3886f, -175.1285f, -147.8946f, 82.91971f, 110.22f, -174.96f, -147.6597f, 83.00413f, 110.4739f, -175.2138f, -147.7441f, 82.76912f, 110.3056f, -175.0456f, -147.5091f ; :MAP_PROJ = 6 ; :MMINLU = "USGS" ; :NUM_LAND_CAT = 24 ; :ISWATER = 16 ; :ISLAKE = -1 ; :ISICE = 24 ; :ISURBAN = 1 ; :ISOILWATER = 14 ; :grid_id = 1 ; :parent_id = 1 ; :i_parent_start = 1 ; :j_parent_start = 1 ; :i_parent_end = 216 ; :j_parent_end = 145 ; :parent_grid_ratio = 1 ; :sr_x = 1 ; :sr_y = 1 ; :FLAG_MF_XY = 1 ; } -- Dr. Michael Sumner Software and Database Engineer Australian Antarctic Division 203 Channel Highway Kingston Tasmania 7050 Australia
