MapServer- read TEMPLATE (mymap.html)- replace Placeholder in TEMPLATE<input type="image" src="[img]">

- deliver mymap.html to the WebServer

Activity chain for mapfile production with CGI

Browser- send request (http://www.server.de/cgi-bin/mapserver?map=mymap.map&...&...)

MapServer- read configuration file (Mapfile) (mymap.map)

…WEB

TEMPLATE mymap.htmlIMAGEPATH „D:\webserver\tmp\“IMAGEURL „/tmp/“

END…LAYER

NAME „water“DATA „rivers“

…- Create and write map in IMAGEPATH

WebServer- receive request- call mapserver program - mapserv(.exe)- deliver CGI parameter to mapserver

WebServer- send mymap.html to the browser- provide image with the map- provide image with the legend etc.

Browser- receive web page mymap.html with source links to the map image and the web form- Visualize the page with functions for navigation and query- mymap.html include link to http://www.server.de/cgi-bin/mapserver?parameter=wert&...&..

Another Example, same techniqueprincipals


MapServer mode

• CGI parameter mode determines how MapServer process requestshttp://server.vn/cgi-bin/mapserv.exe?map=mapfile.map&layer=rivers&mode=map• BROWSE

• default• create maps• build the interactive client page with template• substitution strings for dynamic changes in the template e.g. [img]

• MAP• creates only the map• use in conjunction with the HTML <img …> tag

• REFERENCE, SCALEBAR and LEGEND• create exactly this• Also as images in MapServer’s temp directory

principals


UMN-MapServer 15


MapServer mode II

• ZOOMIN and ZOOMOUT• do exactly this• ZOOMSIZE as zoom factor• ZOOMDIR with positive or negative value for zoom in or out• switch to the mode BROWSE

• QUERY• used for spatial search closest to a point clicked previously in a map

• NQUERY• find more than the nearest feature from the selected search point• or user defined search box

• ITEMQUERY and ITEMNQUERY• For text search in the same way like QUERY and NQUERY

• Additional Modes for querying features

principals


MapServer - Mapfile

• Central map configuration file• A Map consists of Layers and some descriptive elements• Divided in sections for:

• map,• legend,• query map,• reference map,• scale bar,• projection,• layer.

• Declarations of data sources• Combining thematic related layers in one map service• Metadata descriptions for the map and layers

Mapfile - conventions II

• Variable names must be NOT case-sensitive• KEYWORDS in upper case• Strings in double-quotes is recommended• Limitation per default

• MS_MAXLAYERS 200 - max layers per mapfile, changeable in map.h• MAXCLASSES 250 - max classes per layer, changeable in map.h• MAXSTYLES 5 - max styles per class, changeable in map.h• MAXSYMBOLS 64 - max symbols in symbol set, changeable in mapsymbol.h• After edition recompile

• File paths as absolute paths or as paths relative to the location of the mapfile

• In addition, data files may be specified relative to the SHAPEPATH• Comments are designated with a #• Attribute names are case sensitive using the following syntax:

[ATTRIBUTENAME]• Generally ESRI generated shape files have their attributes (.dbf column

names) all in upper-case for instance, and for PostGIS, ALWAYS use lower-case.

• MapServer uses regular expressions supported by operating system's C Library (regex)

• Settings for the map itself• Web object to define how the
