[mapserver-users] Re: WFS GetFeature on Mapserver doesn't work
Hi Rahkonen, I finally got two map files to work. The first one I created using your technique i.e copy paste sample code from wfs_server.html and then made necessary changes. The first which uses shape file as data source is as follows: NAME "Rail_WFS" STATUS ON SIZE 600 600 SYMBOLSET "symbols.sym" EXTENT 67.440106 17.379867 78.390250 25.122977 UNITS METERS SHAPEPATH "C:/ms4w/apache/htdocs/Shape" IMAGECOLOR 255 255 255 FONTSET "fonts.txt" CONFIG "PROJ_LIB" "C:\ms4w\proj\nad" WEB IMAGEPATH "/ms4w/tmp/ms_tmp/" IMAGEURL "/ms_tmp/" METADATA "wfs_title""GMap WFS Demo Server" ## REQUIRED "wfs_onlineresource" "http://127.0.0.1/cgi-bin/mapserv.exe?"; ## Recommended "wfs_srs" "EPSG:42304 EPSG:42101 EPSG:4269 EPSG:4326" ## Recommended #"ows_schemas_location" "http://ogc.dmsolutions.ca"; ## Optional END END PROJECTION "init=epsg:4326" END LAYER NAME "state" METADATA "wfs_title""state" ## REQUIRED "gml_featureid" "ID" ## REQUIRED "gml_include_items" "all" ## Optional (serves all attributes for layer) END TYPE POLYGON STATUS DEFAULT DATA state PROJECTION "init=epsg:4326" END DUMP TRUE ## REQUIRED CLASS NAME "state" STYLE COLOR 200 255 0 OUTLINECOLOR 120 120 120 END #TEMPLATE "Demo_query_body_state.html" END END # Layer END # Map File The second mapfile is the one about which I had made this post.I had struggled a lot with this since yesterday.

[mapserver-users] Re: WFS GetFeature on Mapserver doesn't work
Hi Rahkonen, Thanks for your reply. You are right again.The Getcapabilities is showing the layer and there is one layer only. But Getfeature is showing the same thing it had shown earlier i.e it is NOT showing the features and the details of those features. GetFeatures O/p http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd http://mapserver.gis.umn.edu/mapserver http://localhost:81/cgi-bin/mapserv.exe?map=d:/Delhi1_wfs_postgres.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=delhi_district&OUTPUTFORMAT=XMLSCHEMA";> − missing Another interesting thing.Although I have given REQUEST=GetFeature the output is showing REQUEST=DescribeFeatureType. Is it because mapserver is unable to find the features within the layer and so it is changing the type of request? What changes do I make so as to get GetFeatures working?

Hi Rahkonen, Thanks for your reply. You had rightly pointed out that DUMP TRUE was missing.

So do I need to put a XML template.If so pls send me an example. Do I need to put all the three templates i.e HEADER,TEMPLATE & FOOTER. If yes pls send example for all three. You have said "Feature List is empty" and so it doesn't appear in the Getcapabilities. What corrections are required in the layer settings for it to appear in the Getcapabilities?

[mapserver-users] Re: mapserver not generating proper map
Hi BrainDrain, Thanks for your reply. Your solution doesn't work. the code relating to the info control is the culprit. It started giving errors, then I commented it but after that the map was not getting displayed. Finally after a lot of effort I got the map but with problems stated earlier. After applying your code I find that the background is occupying 600 * 600 but the actual layers are coming small even though magnification level is 6 or more. I think it is Openlayer 2.8 which is causing the problem.So I need to go back to OL2.7. But then is it possible to hav Get Feature Info in 2.7 from shape files? If you know how to do it pls send code across. -- View this message in context: http://n2.nabble.com/mapserver-not-generating-proper-map-tp4776875p4779918.html Sent from the Mapserver - User mailing list archive at Nabble.com. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] mapserver not generating proper map
Hi,
I am generating a simple map but mapserver is not generating a proper map.
In fact initially it produced a proper one but after that due to code
changes or some other reason started producing this one.
My code to call mapserver is:
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";>
var mapview, layer, layer1, map;
function init() {
//alert("in init");
map = new OpenLayers.Map('<%=map.ClientID%>');
//
layer = new OpenLayers.Layer.WMS("OpenLayers WMS",
"http://172.16.0.144:9000/cgi-bin/mapserv.exe?";, { map:
'Shape/newwr1.map', layers: 'STATE', 'format': 'png' });
//layer1 = new OpenLayers.Layer.WMS("RLine",
"http://172.16.0.144:9000/cgi-bin/mapserv.exe?";, { map: 'Shape/newwr1.map',
transparent: 'true', layers: 'RailwayStations', 'format': 'png' });
highlightLayer = new OpenLayers.Layer.Vector("Highlighted
Features", {
displayInLayerSwitcher: false,
isBaseLayer: false
}
);
map.addLayers([layer]);
map.setCenter(new OpenLayers.LonLat(73.25, 20.35), 6);
//for (var i in infoControls) {
//infoControls[i].events.register("getfeatureinfo",
this, showInfo);
//map.addControl(infoControls[i]);
//}
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.zoomToMaxExtent();
//infoControls.click.activate();
}
and my map file is:

But when my map comes up it is having a BBOX size of 256 * 256.
the url of the generated map is as follows:
http://172.16.0.144:9000/cgi-bin/mapserv.exe?MAP=Shape%2Fnewwr1.map&LAYERS=STATE&FORMAT=png&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326&BBOX=0,-90,180,90&WIDTH=256&HEIGHT=256
Why does it happen?
Is it because of some wrong openlayers code I have written or some bug?
What should I do to get back to the desired size i.e 600 * 600
Thanks for your attention & efforts.

[mapserver-users] getting Feature Info data directly from .shp files
Dear Friends, I want to get the Feature Info data directly from .shp files i.e shape files. Previously I had put all data into the database (postgres) then ran queries on the DB and the data returned is shown in a pop up.

Hi, I have got several shapefiles from which I am able to display map using mapserver. But the problem is that it has a srid value of -1 i.e no projection. As a result of this several functionalities which uses geometry are not working. I think the default srid value is 4326.Pls confirm. I want to convert the srid value from -1 to 4326. How can I do this using QGIS? I know this is possible using GEOMEDIA Web 6.0. If anybody has any idea or tutorial regarding .shp manipulation using Geomedia pls send it across.

[mapserver-users] symbol problem
Dear Friends, I have created a map file using QGIS and after that the symbols had to be changed once.So I imported the symbols into QGIS and created a fresh map file. But now again the symbols need to be changed and I followed the above process. But this time although symbols r getting imported into QGIS and map is created but it does not show up in the map. The smbols this time are a bit bigger and do not confirm to a particular shape like circle,ellipse etc. The map file is showing symbol as "circle". So where is the exact problem and how to overcome it. The other issue is about how does mapserver know the path of the .svg file when the only thing i.e written in the map file is "circle","ellipse". How how it gets the entire path to the svg files for showing? Thanks for ur reply.

[mapserver-users] maploading problem
Dear Friends, The map from a mapserver takes enormously long time to load about 5 mins when the server machine on which it works is set to accept public IP i.e uses DHCP. Most of the time it does not load at all - only a pink background is seen in place of the map. After changing a machine IP to public I also change the httpd file in conf folder of Apache to localhost:8085. But despite this the above problem occurs. Can someone tell me the cause of the problem and how to resolve? Whether it can be solved by implementing mapfish?

Re: [mapserver-users] display feature name beside feature
Hi Steve, Thanks for your reply. Regarding the railway points I was able to see the points before doing all this. I did all this just to see the Labels i.e names of the railway stations beside the points But I am not able to see this. Can u tell me where the problem is? What am I doing wrong? Thanks again.

Re: [mapserver-users] display feature name beside feature
Hi Michael, Thanks for your reply. I had gone thru' the links you have given before making this post.But I am having the problems given in the link below: http://n2.nabble.com/font-error-while-trying-to-show-Label-on-map-td3654455.html#a3654455 When using truetype I get the error probably bec' I am not able to specify the fontset file. So I need to know the following: 1) What kind of file is the fontset file?I think it is a text file 2) Where do I keep the fontset file - in the same folder as the map file or in different folder.If different folder how do I specify the path in the map file. 3) Where do I keep the fonts? Is it okay if I keep it in the Windows Font Folder i.e C:/Windows/Fonts 4)How do I specify the path of the fonts in the fontset file? Pls give ur answer so as to solve this problem.

Re: [mapserver-users] turning on layers at a particular zoom level
Hi Bill, Thanks for your reply. I am now loading the layers in groups instead of individually. First I am loading the base layer followed by 4 groups of layers, first group contains 2 while others contain 3 each. But the problem now is that at PageLoad for the first time the layers of group1 are not visible because it is getting overlapped by the other layers. The other layers are also not visible bec' they are mandated to be visible at higher zoomin levels because of max/min scaledom. Now if I load the group1 layers last then not only is it visible at initial zoom level but also at higher zoom levels bec' in that case it is overlapping the other layers mandated to be visible at that level. So how to tackle the problem. Can it be solved by changing the z-index of the first group at initial PageLoad. Pls provide some solution to this problem.

[mapserver-users] check if a layer exists and remove it
Hi,
I am declaring a layer at PageLoad in the following way:
choice_features = new OpenLayers.Layer.Vector("choice_features", { style:
v_style });
Then I am adding the layer in a different function as below:
map.addLayer(new OpenLayers.Layer.GML("choice_features",
"XML1/FeatureGML.xml"));
But I want to check if this layer exists and remove it before adding it to
the map using the addLayer function. This will ensure that the layer is
created afresh with every fresh request.
For this I have done the following but it doesn't work:
if (map.getLayersByName("choice_features") != null) {
map.layers["choice_features"].removeFeatures(map.layers["choice_features"].features);
//alert("layer removed");
}
But I get error in the getLayersByName() function.It says object doesn't
support this property.
Can u suggest an alternative method.
Thanks.

Re: [mapserver-users] turning on layers at a particular zoom level
Hi,
Thanks for ur reply.
1)What is the syntax for send request against a Group?
2)If I just write the name of the group within layer then will it be placed
against the group?
3) What is the syntax for checking the zoom level of a map so that once a
zoom level is reached I can call a group of layers?
Regards.

RE: [mapserver-users] turning on layers at a particular zoom level
Hi David, Thanks for your reply. I wanted to have 3 layers displayed b/w scale of 1.2M and 1.15M and so I have added set MAXSCALEDENOM /MINSCALEDENOM as follows: LAYER NAME 'WaterBody' TYPE POLYGON DATA 'C:\ms4w\Apache\cgi-bin\Shape\WaterBody.shp' METADATA 'wms_title' 'WaterBody' END STATUS OFF TRANSPARENCY 100 PROJECTION 'proj=longlat' 'ellps=WGS84' 'datum=WGS84' 'no_defs' '' END CLASS NAME 'WaterBody' MAXSCALEDENOM 200 MINSCALEDENOM 150 STYLE SYMBOL 0 SIZE 2 OUTLINECOLOR 0 0 0 COLOR 150 123 90 END END END 1)Pls tell me whether I hav added the things at the correct place. 2) Can I also add it within the layer properties? 3) I find that the layers are being added at PageLoad.This I found out by looking at the number of items being added at the bottom left corner of IE. The number of items has nearly doubled due to the addition of the 3 layers. Is there any way by which I can stop the layers from being added at PageLoad i.e they should be added only when the desired scale is reached. 4) How to use TileCache or GeoWebCache i.e js code?

Re: [mapserver-users] turning on layers at a particular zoom level
Hi, Thanks for your reply. I went thru the link and read about MAXSCALEDENOM/MINSCALEDENOM. So MINSCALEDENOM is the minimum scale level at which a layer will become visible. But I am a bit confused.When the map loads for the first time it has a zoom level of 7 as given in the code below. map.setCenter(new OpenLayers.LonLat(74.25, 20.35), 7); In terms of scale it is showing 1:3M. What is M? If I increase the zoom level i.e do zoom in, scale becomes 1:856K and 1:256K etc i.e scale decreases. So If want a layer to be visible at a scale level of 1:2M what do I write in the mapfile? How to use TileCache or GeoWebCache?Pls give the js code.

[mapserver-users] turning on layers at a particular zoom level
DEar Friends, I have 12 layers in my map and it is taking to long to load.Therefore I decided to turn on only 2 layers at Page Load. Rest of the layers I want to turn on at a particular zoom level.How can I check the zoom level and turn on these layers. How can make the map load faster especially on page reload? Is it possible to cache the map or is there some other technique?

Re: [mapserver-users] layers not getting separated
Hi, Thanks for your reply. My problem is solved. Problem was in the map file.The status of each layer was "DEfault", so all the layers were loading and not turning off.Then I changed the status of all except the base to "OFF".I found that it was turning on and off. But now I am having another issue.I have 12 layers in my map and it is taking to long to load.Therefore I decided to turn on only 2 layers at Page Load. Rest of the layers I want to turn on at a particular zoom level.How can I check the zoom level and turn on these layers. Thanks for ur reply.

[mapserver-users] layers not getting separated
Dear Friends, I am displaying a map using mapserver and openlayers.The map is displayed using a map file kept within a folder containing shape files. Although the map is getting displayed, if I add more than one layer the layers are not getting separated. i.e I can see the layer in the Layer switcher but if I check or uncheck nothing happens. This means all the layers are coming as a single image. I feel that there is something in the map file which I have ommitted and so this happens. I used QGIS to create the map file. Looking for a solution.

[mapserver-users] coloring features on the basis of query
Hi, I am trying to implement something called "Find Feature" on a map. The user will select parameters for a query which will be executed on the DB and the DB will return some geometry's. For eg, the query could be like " Select the_geom from india_state where pop_tot01 > 100" Now I need to know the following: 1) What data type to use for collecting geometry returned by the above sql query? 2) The above query will return geometry of some states.As similar query will return geometry of some districts. For these states and districts I need to give a different color with a Label like population > 100.How can I do this dynamically? 3) The coloring and labeling will be temporary and will change with every query that is fired at the database.
