I'm aware Zoo project has an API with proj4js built-in. However, I haven't found yet how to pass it the following parameters: +proj=nzmg +lat_0=-41.0000000000 +lon_0=173.0000000000 +x_0=2510000.0000000000 +y_0=6023150.0000000000 +a=6378388 +rf=297 +no_defs +nadgrids=nzgd2kgrid0005.gsb I've instead added the official proj4js.js file and I am trying to re-project from NZMG to NZTM. For source projection I used: +proj=nzmg +lat_0=-41.0000000000 +lon_0=173.0000000000 +x_0=2510000.0000000000 +y_0=6023150.0000000000 +a=6378388 +rf=297 +no_defs +nadgrids=nzgd2kgrid0005.gsb and destination projection I used: +proj=tmerc +lat_0=0.0000000000 +lon_0=173.0000000000 +k_0=0.9996000000 +x_0=1600000.0000000000 +y_0=10000000.0000000000 +a=6378137 +rf=298.257222101 +no_defs +towgs84=0.000,0.000,0.000 I've added in the same directory as the proj4js.js file the nzgd2kgrid0005.gsb file. Can proj4js.js using zoo project API use the nadgrids parameter to access the file locally without using a browser? Does proj4js even support the nadgrids parameter?
