Technically looks good to me. Just for our information: are there raster formats handled by GDAL that will make use of this projection method ? > > Example output of gdalsrsinfo look's like this: > > gdalsrsinfo "+proj=sch +plat_0=30.3 +plon_0=45.1 +phdg_0=-12.2 > > > >+datum=WGS84" > > PROJ.4 : '+proj=sch +plat_0=30.3 +plon_0=45.1 +phdg_0=-12.2 +h_0=0 > +datum=WGS84 +units=m +no_defs ' > > OGC WKT : > PROJCS["unnamed", > GEOGCS["WGS 84", > DATUM["WGS_1984", > SPHEROID["WGS 84",6378137,298.257223563, > AUTHORITY["EPSG","7030"]], > AUTHORITY["EPSG","6326"]], > PRIMEM["Greenwich",0, > AUTHORITY["EPSG","8901"]], > UNIT["degree",0.0174532925199433, > AUTHORITY["EPSG","9122"]], > AUTHORITY["EPSG","4326"]], > PROJECTION["Spherical_Cross_Track_Height"], > PARAMETER["peg_point_latitude",30.3], > PARAMETER["peg_point_longitude",45.1], > PARAMETER["peg_point_heading",-12.2], > PARAMETER["peg_point_height",0]] > > > > This is my first time working with OGR parameters.
