############################################################################### ### Polar2Grid Example Grid Configuration File ### ############################################################################### # Description: This file provides a few working examples of various types of # grids that can be added to polar2grid. This file is to help # a user add their own grids to polar2grid in addition to the # documentation at # http://www.ssec.wisc.edu/software/polar2grid/dev_guide/grids.html # # PROJ.4 Grids: # PROJ.4 grids may have 'None' for grid size, origin, or pixel size to be # considered 'dynamic'. PROJ.4 grid components: # - Grid Size (Width and Height): Number of pixels of the grid # - Pixel Size: Size of each individual pixel in the grid domain # (meters in most cases, degrees for latlong projections). # **Y Pixel Size must be negative** # - Origin: The top-left location in the grid domain. Usually in meters, but can be specified as degrees "35.0deg". # # Pixel size or grid size may be unspecified (dynamic), but not both. # Dynamic grid attributes are calculated from the data being remapped. # Of the examples below only 'p4_211e' is a static PROJ.4 grid, the others # are dynamic in some way. # PROJ.4 Parameters: http://trac.osgeo.org/proj/wiki/GenParms # ############################################################################### ### NOTE: Polar2Grid does not use this file by default ### ### Use `--grid-configs my_grids.conf` to add your own grids ### ############################################################################### # Entries for use with polar2grid v2.2 installation verification # p2g_grid_helper.sh miami -80.2 25.7 300 300 1000 750 miami, proj4, +proj=lcc +datum=WGS84 +ellps=WGS84 +lat_0=25.700 +lat_1=25.700 +lon_0=-80.200 +units=m +no_defs, 1000, 750, 300.000, -300.000, -81.707deg, 26.708deg # # grid_name, proj4, proj4_str, width, height, pixel_size_x, pixel_size_y, origin_x, origin_y my_211e, proj4, +proj=lcc +a=6371200 +b=6371200 +lat_0=25 +lat_1=25 +lon_0=-95 +units=m +no_defs, 5120, 5120, 1015.9, -1015.9, -122.94deg, 59.86deg my_lcc_fit, proj4, +proj=lcc +datum=WGS84 +ellps=WGS84 +lat_0=25 +lat_1=25 +lon_0=-95 +units=m +no_defs, None, None, 1000, -1000, None, None my_simple_square, proj4, +proj=lcc +datum=WGS84 +ellps=WGS84 +lat_0=25 +lat_1=35 +lon_0=-95 +no_defs, 1500, 1500, 1000, -1000, None, None my_latlon, proj4, +proj=latlong +datum=WGS84 +ellps=WGS84 +no_defs, None, None, 0.0057, -0.0057, None, None my_latlon_250, proj4, +proj=latlong +datum=WGS84 +ellps=WGS84 +no_defs, None, None, 0.00225, -0.00225, None, None my_polar_canada, proj4, +proj=stere +datum=WGS84 +ellps=WGS84 +lat_0=90 +lat_ts=45.0 +lon_0=-150 +units=m, None, None, 1000, -1000, None, None
