Converting from ArcIMS axl-files to Mapserver map-files

Norges geologiske undersøkelse (NGU) faser nå ut ArcIMS. ArcIMS-tjenestene skal i hovedsak over til Mapserver. Vi har et stort antall tjenester og fant det nødvendig å lage et XSLT-script som konverterer axl-filer (ArcIMS) til .map-filer (Mapserver).


Geological Survey of Norway (NGU) phases out ArcIMS. ArcIMS services will mainly be ported to the Mapserver. We have a large number of services and found it necessary to create an XSLT script which converts from axl-files (ArcIMS) to map-files (Mapserver).


Execution:

  • java org.apache.xalan.xslt.Process -IN foo.axl -XSL axl2mapNGU.xsl -OUT foo.map
  • Add in axl-file right after first line - open file in Web browser: <?xml-stylesheet type="text/xsl" encoding="iso-8859-1" href="axl2mapNGU.xslt"?>


Other info:

  • Support renderer types that are mostly used by the NGU. Should be easy to add renderer types with the <xsl:template match="...">
  • GROUPRENDERER (ArcIMS) with multple elements will result in multiple CLASS (Mapserver) sections with identical names. Edit and integrate these into unique classes manually.
  • SCALEDEPENDENTRENDERER (ArcIMS) is supported to some extent. Alternativly you can create a separate layer for this with its own scale range.
  • The type attribute renderer (ArcIMS) are mapped to a SYMBOL reference (Mapserver) like: SYMBOL "star" or SYMBOL "dot". Additional symbols must be defined for this.
  • The character attribute in TRUETYPEMARKERSYMBOL (ArcIMS) are mapped to a SYMBOL reference (Mapserver) like: SYMBOL "135". Additional symbols must be defined for this.
  • Implements renderers like RASTER_RENDERER, RASTER_EXACT, RASTER_OTHER
  • Uses patterns (Mapserver - e.g. [ServiceAbstract]) to be replaced by user defined content after conversion.
