if (eg instanceof EsriPolygon) {
double[] latlonarray = ((EsriPolygon)eg).getLatLonArray();
// latlonarray in radians, but don't modify! Make copy, then change copy
double[] newlla = new double[latlonarray.size];
System.arraycopy(0, latlonarray, 0, newlla, latlonarray.size());
ProjMath.arrayRadToDeg(newlla);
// newlla has coords. EsriPoint, EsriLine have different methods for
getting coords, check API
