Important notes when upgrading to MS4W 5 from MS4W 4

REQUIREMENTS.txt

  • always first follow the instructions in the file /ms4w/REQUIREMENTS.txt to install the updated "Microsoft Visual C++ Redistributable" on your server

SWIG MapScript

PHP

  • test PHP MapScript at the commandline by executing:
    setenv.bat
    php -dextension=C:/ms4w/Apache/php/ext/php_mapscript.dll -r "echo msGetVersion();"
    
  • as of MS4W 5.0, there is no external file to include in your PHP scripts (the constants and functions are wrapped inside the MapScript PHP extension instead)
  • see the updated example scripts here on the Wiki, such as:
  • quickmap.php has also been updated (see locally at /ms4w/Apache/htdocs/quickmap.php)
  • be aware that with the MapServer 8 release, many deprecated things have been removed and will now throw an error. For example, there is no longer a setMetaData() function for a Layer, in SWIG MapScript. Instead here is a working example:
    <?php
      $oWMSLayer->metadata->set("wms_name", "popplace");
      $oWMSLayer->metadata->set("wms_srs", "EPSG:3978");
      $oWMSLayer->metadata->set("wms_server_version", "1.1.1");
      $oWMSLayer->metadata->set("wms_format", "image/png");
    ?>
    

Python

  • test Python MapScript at the commandline by executing:
    setenv.bat
    python -c "import mapscript; print (mapscript.msGetVersion())"
    
  • quickmap.py has been included in /ms4w/msplugins/mapscript/python/ (follow the instructions at top of file)
  • the GDAL Python utilities can be called at the commandline such as:
      setenv.bat
      gdal_merge --help
      gdal2tiles --help
    

PROJ

  • Apache's conf & setenv.bat now set PROJ_LIB to PROJ's new location:
      \ms4w\share\proj;\ms4w\share\proj\grids
    
    If your mapfiles set a PROJ_LIB (which is not recommended, as MS4W's Apache does this for you) you will have to update your PROJ_LIB value
  • MS4W 5.0 includes PROJ 8.2, which contains many changes, allowing to dynamically pull in various grids, to improve accuracy
    • see settings in /ms4w/share/proj/proj.ini
    • since we are involved in displaying maps over the internet, we should likely have these grids locally on the server
      • execute the following to install the grids (into /ms4w/share/proj/)
          setenv.bat
          proj-install-grids.bat
        

Removed Mapfile Parameters

The following (formerly deprecated) mapfile parameters will now cause errors in your mapfile, you MUST REMOVE them:

  1. DUMP TRUE

Instead, you can configure querying of your layer by using METADATA instead, such as:

LAYER
  ...
  METADATA
    "wms_title"         "Populated Places"
    "wms_include_items" "all"
    "gml_include_items" "all"
    "gml_featureid"     "ogc_fid"	
  END #metadata
  ...
END #layer
  1. OPACITY at the LAYER-level

Instead it must be inside a COMPOSITE object:

LAYER
  ...
  COMPOSITE
    OPACITY 40
  END #composite
END #layer
  1. COLOR at the LAYER-level

Instead it must be inside a STYLE object:

LAYER
  ...
  STYLE
    COLOR 120 120 120
  END #style
END #layer
