const getEPSGCode = require("get-epsg-code"); const proj4string = "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs"; const epsgCode = getEPSGCode(proj4string); // 3857
Get the EPSG code for input without the need for a remote server
Take a CSV of Coordinate Reference System formats, hash the columns and stores the result in a binary file.
This package goes only one way. It only gets EPSG codes for a given input. It cannot provide coordinate information for an EPSG code.
