I detect that the file ortho.js only work if I change the line con = Math.abs(lat0) - Proj4js.common.HALF_PI; to the line con = Math.abs(this.lat0) - Proj4js.common.HALF_PI; I also coment the lines if ((Math.abs(con) >= Proj4js.common.EPSLN) || (Math.abs(x) >= Proj4js.common.EPSLN)) { lon = Proj4js.common.adjust_lon(this.long0 + Math.atan2((p.x * sinz * this.cos_p14), (con * rh))); } The file eqdc.js has a similar problem. I had to change it from var lat = this.phi3z(this.ml,this.e0,this.e1,this.e2,this.e3); to var lat = this.phi3z(ml,this.e0,this.e1,this.e2,this.e3); The file vandg.js was also changed by me from lat = -(-m1 * Math.cos(th1 + PI / 3.0) - c2 / 3.0 / c3) * Proj4js.common.PI; to lat = -(-m1 * Math.cos(th1 + Proj4js.common.PI / 3.0) - c2 / 3.0 / c3) * Proj4js.common.PI; This are the bugs that I detect. There are other problems that i'm testing and will report soon." defect closed major 1.0.1 core 1.0.0 fixed
