VS: [mapserver-users] WMS problem

Fri Feb 27 07:42:01 EST 2009

Hi,

It is for sure possible to fix your problem, but because MapLab is no more supported or developed in any way I would suggest you to select some other application to play with.  I could guess that there is nothing wrong with your Mapserver configuration because you do see the image in the beginning.  Zooming problems are most probably caused by MapLab and struggling with is would of course be educational but if you are searching for some permanent system, go and get a fresh Mapserver version (5.2 or 5.4 beta) and choose another client.

Aihe: Re: [mapserver-users] WMS problem

	Hi Pietro, 

	1.I've tried to invoke mapserver in cgi mode and it seems ok. 
	http://webgis.provincia.biella.it/cgi-bin/mapserv?map=/opt/fgs/apps/mapservergeo/map/basewms.map&mode=map&layer=stati 
	2. We looked on the apache log file and we fixed some errors we had in a php file. 
	Anyway things are not changed. 
	http://webgis.provincia.biella.it/apps/maplab/projects/gmf_apps/basewms4/wmdmap.php 
	Please, do you have anything else to suggest? 
	Thank you very much for your help 
	ciao

		Hi Andrea, 

		1. no 
		2. no matters 
		3. It is difficult to answer... 

		If the problem is EXTENT & PROJECTION, remember that a .map file has the PROJECTION set at map level and PROJECTIONs set at layers level; the map Projection is the projection system of the result of the map (i.e. the map image), the layer Projection is the projection system of the data source of the layer. If a layer datasource projection differs from the map projection, you must to set it, otherwise ms try to project the data according with map projection. 
		Try invoke mapserver in cgi mode to see the results: http://the.host/cgi-bin/mapserv?map=/path/of/the.map&mode=map&layer= ... 

		Imho your problem isn't the map, but occurs in your php script. Take a look on the php error log: it is a text file, its path is set in your php.ini file (error_log directive, can be an absolute or relative path) 

		4. obviously scale is nonsense when using non-projected reference systems like epsg:4326, but mapserver does not know. 

		hth

			Hi, we have this system working with MapServer version 4.8.2, PHP version 
			4.4.2. I am trying to do a map that shows both layer (WGS84 shapefile) and 
			WMS data togheter. The starting response is ok, but I get the blank image 
			from the first pan or zoom on. This is the example URL: 
			http://webgis.provincia.biella.it/apps/maplab/projects/gmf_apps/basewms4/wmdmap.php <http://webgis.provincia.biella.it/apps/maplab/projects/gmf_apps/basewms4/wmdmap.php> 
			  I guess the problem is due to wrong parameters for EXTENT, SIZE and 
			PROJECTION in the mapfile. These are: EXTENT -15 25 40 70 SIZE 470 520 
			PROJECTION "init=epsg:4326".  The question are: 1. the SIZE (in pixel) has 
			to be proportional to the EXTENT? 2. if yes, how to obtain the right values 
			for the EXTENT? 3. if not, where is the problem? 4. in a map with geographic 
			non-projected data like this, is correct to have value for scale of the 
			representation since UNITS are DD?  I would be very grateful for any help 
			from you all, thanks! Best regards andrea ardito  P.S. If I set no layer in 
			the map file, and I try to represent only WMS layer (adding them from 
			"Servizi WMS" button), it works.
