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

• 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:
  • query example: MS4W 5.x
  • new layer example (WMS layer, polygon + opacity, point): MS4W 5.x
  • WMS wrapper example: MS4W 5.x
  • setOpacity() example: MS4W 5.x
• 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

• 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

• 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 after installing MS4W

      setenv.bat
      proj-install-grids.bat
