Parsing error with vertical projection information in PRJ file.

[chriserickson]

I have a shape file which has a PRJ file which defines a vertical projection. When trying to parse it, I get an error "Unexpected token ,".

The error appears to be from the first line this method, specifically the JSON.parse call.:

module.exports = function(wkt, self) {
  var lisp = JSON.parse(("," + wkt).replace(/\s*\,\s*([A-Z_0-9]+?)(\[)/g, ',["$1",').slice(1).replace(/\s*\,\s*([A-Z_0-9]+?)\]/g, ',"$1"]'));
  var type = lisp.shift();
  var name = lisp.shift();
  lisp.unshift(['name', name]);
  lisp.unshift(['type', type]);
  lisp.unshift('output');
  var obj = {};
  sExpr(lisp, obj);
  cleanWKT(obj.output);
  return extend(self, obj.output);
};

An example PRJ is:

PROJCS[
    "Custom_NAD_1983_UTM_Zone_17N",
    GEOGCS["GCS_North_American_1983",
        DATUM["D_North_American_1983",
            SPHEROID["GRS_1980",6378137.0,298.257222101]
        ],
        PRIMEM["Greenwich",0.0],

]

we rely on proj4js when I comes to parsing those

This is fixed in proj4js issue #120.
