I consolidate all my .map files and data under a root folder. (eg. c:\data)

Under the url when accessing .map file via Mapserver, instead of defining an absolute full path:


I will like to specify a relative pathing to c:\data like this:


Or have some way to replace c:\data with a keyword (eg. DATA_ROOT) like this:


Is one of the above possible? Also, I am using the pre-built binaries version of Mapserver.

  • There is no concept of a data root, for a mapserver installation, or for a mapserver service. You can use local references within any map file to include other map files – nmtoken Mar 12 at 6:31

I think it would not be a good idea to expose the internal directory structure in URLs, so both the .exe and the .map files are configured explicitly behind a virtual path:

<Location "/thismap">
  ScriptAlias "c:/ms4w/Apache/cgi-bin/mapserv.exe"
  SetEnv MS_MAPFILE "c:/data/config/this.map"
<Location "/anothermap">
  ScriptAlias "c:/ms4w/Apache/cgi-bin/mapserv.exe"
  SetEnv MS_MAPFILE "c:/data/config/another.map"

resulting in, e.g., http://localhost/thismap?layer=sample&mode=map.

And then it makes sense to use a macro for these:

<Macro MSMap $URL $config>
  <Location "$URL">
    ScriptAlias "c:/ms4w/Apache/cgi-bin/mapserv.exe"
    SetEnv MS_MAPFILE "c:/data/config/$config"

Use MSMap /thismap   this.map
  • Thank you, this solution will solve my problem! – ssaga Mar 13 at 1:59
