系統
Linux+MapServer-5.2.1+shpfile
［1］安裝apache2.2
［2］安裝mapserver-5.2.1
把mapserv復制到${apache_home}/cgi-bin
［3］用qgis導出mapscript文件
# Map file generated by QGIS version 0.7.4
# Edit this file to customize for your interface
# Not all sections are complete. See comments for details.
MAP

# Start of web interface definition. Only the TEMPLATE parameter
# must be specified to display a map. See Mapserver documentation

［4］在OpenLayers中調用地圖文件
