Class PrjParser

java.lang.Object
  org.cts.parser.prj.PrjParser

public class PrjParser
extends Object

Parser for PRJ / WKT (OGC & ESRI) String. This very simple parser works in tree steps: 1. it parses the PRJ String and produces an abstract tree, without any assumptions on it being a valid OGC WKT String. 2. it walks the tree looking for the values needed for transformation into a proj4 description string. 3. the proj4 description string is passed to the org.jproj.parser.Proj4Parser that builds the CRS.
