KML Map Server

by

KMLMapServer trasforma la tua installazione UMN MapServer in un flessibile server di dati KML per la visualizzazione diretta in Google Earth.

Obbiettivi

Track to Andolla Refuge Lo scopo di questo progetto è aggiungere la capacità di servire dati in formato KML a una qualsiasi installazione di UMN MapServer. Il tutto funziona senza alcuna configurazione aggiuntiva o con modifiche minimali, anche a seconda del grado di personalizzazione che si desidera ottenere. In linea di massima, è sufficiente installare il pacchetto in una directory del proprio server web e il sistema funzionerà senza alcun bisogno di configurazione aggiuntiva. In caso di bisogno, i parametri di configurazione sono impostati tramite metadati nel mapfile di MapServer, non c’è quindi necessità di imparare una nuova sintassi e di mantenere un ulteriore file di configurazione. Il grande vantaggio della generazione dinamica dei layer basata su un server di mappe, è che questi possono venire aggiornati in tempo reale, senza rischio di distribuire dati obsoleti.

Storia

Questo progetto nasce dalla constatazione che sebbene avessimo diversi server di mappe attivi, questi erano per lo più relativi ad aree montane e ad itinerari escursionistici che si sarebbero enormemente avvantaggiati della possibilità di una vista tridimensionale. Perché quindi non sfruttare il motore gratuito di Google Earth per visualizzare i dati provenienti da MapServer?

Requisiti tecnici

Logo MapServerPer utilizzare KMLMapServer occorre
  • una installazione funzionante di UMN MapServer, configurata come server WMS se si desidera servire anche dati raster
  • PHP5 con php_mapscript

Come funziona

Il server di layer

Weismies Hutte KMLMapServer è stato pensato con in mente il modello dei webservice OGC WFS, laddove possibile, i parametri sono gli stessi e hanno lo stesso significato. Normalmente, il servizio KMLMapServer viene invocato con una chiamata URL in stile CGI, una chiamata tipica potrebbe essere: http://www.myserver.com/kmlservice.php?map=/maps/mapfile.map&typename=roads,rivers In questo esempio i layer “roads” e “rivers” del mapfile /maps/mapfile.map sono generati e spediti al browser. Non è necessario specificare uno o più nomi di layer, se non viene specificato nessun layer, il servizio restituice un “folder” contenente tutti i layer del mapfile, sotto forma di collegamenti di rete (Network Links nel gergo di Google Earth).

Il server di icone

Icons in Google Earth Il server di icone è un pacchetto indipendente che permette la creazione di immagini PNG per i simboli usati nei layer di tipo POINT. È accessibile tramite lo stesso URL del servizio principale, il valore del parametro “request” è in questo caso “icon”. Per alcuni esempi di icone generate in questo modo, vedete l’immagine sopra (clic per allargare).

Caratteristiche

  • output KML e KMZ (compresso)
  • Semplice sistema di cache per ridurre il carico del server nei grandi file vettoriali
  • Server di simboli (icone) indipendente per i layer di punti
  • Finestrelle informative (fumetti) personalizzabili tramite template con sostituzione di attributi
  • Supporto (limitato) agli stili e alle classi di MapServer per la creazione di mappe tematiche
  • Supporto (limitato) ai filtri in stile OGC sulle singole richieste di layer vettoriali
  • Supporto ai raster tramite collegamenti di rete al server WMS
Serving Raster from MapServer WMS in Google EarthPer usufruire appieno di alcune di queste caratteristiche, potrebbe essere necessario intervenire sulla configurazione del mapfile.

Problemi noti e limitazioni

  • Stili e classi:
    • viene considerato solo l’ultimo stile per ciascuna classe
    • solo i seguenti parametri sono analizzati: color, outlinecolor, backgroundcolor, symbol, size e width
    • l’espressione usata per la classificazione deve essere una espressione regolare
  • Poligoni:
    • i poligoni con riempimento non vengono correttamente disegnati sulle aree montane (questo è probabilmente un problema legato a Google Earth e non a KMLMapServer), il riempimento dei poligoni è quindi disabilitato
    • i confini dei poligoni non seguono correttamente i confini del terreno, un define(‘TREAT_POLY_AS_LINE’, true) ne provoca la conversione in linee

Configurazione

La maggior parte delle caratteristiche di KMLMapSever è pienamente funzionante senza alcuna configurazione aggiuntiva. La configurazione avviene sia tramite parametri passati in stile CGI nella query string sia tramite metadati nel mapfile.

CGI-PARAMETERS

Name Type Required Values Notes
request string no kml kmz icon request type (OGC WFS like)
map string yes   path to mapfile
typename string (can be a CSV list) no   layer(s) to be served, if empty all layers are served as network links
filter string no   well formed XML OGC filter, is active only when a single layer is requested
bbox string no   standard bbox (not yet implemented)
encoding string no   mapfile and attributes encoding, default to ISO-8859-1

METADATA

KMLMapServer re-use most of existing OGC metadata taken from the LAYER section of the mafile, and define a few of its own. None of them are required, but if you want to serve rasters you already need them in order to have a working WMS MapServer installation. Note for rasters: add EPSG:4326 to WMS_SRS metadata on all mapfile layers, otherwise WMS will not work with Google Earth.
Name Meaning Layer type Notes
RESULT_FIELDS The column from which to take the name for the feature Vector Defaults to the first column, the name is displayed in Google Earth Balloons and table of contents
DESCRIPTION_TEMPLATE Custom Balloons template Vector If present, this is used for placemark features Balloons. Parameters surrounded by “%” char are substituted with real values from the corresponding field for the feature
BALLOON_TEMPLATE Custom balloon (tooltip) template Vector If present, this is used to build the tooltip. HTML formatting is possible, $[name] ans $[description] are substituted.
DESCRIPTION OWS_TITLE WFS_TITLEWMS_TITLE Layer description All All those metadata are searched (in this order) to get a layer description
KML_CACHE Cache life Vector Number of seconds after which the cache will expire for a particular layer, if empty or not exists, the cache will be disabled for that layer. Defaults to 0 (cache disabled)
KML_SKIP Skip this layer All Do not serve this layer, default to false

    Ciao, non se scribere molto bene in italiano ma poso leggere. Per cuesto adesso scribo in spagnolo. Escusatemi.

    Estimados, quisiera saber como debo instalar esta aplicacion, tengo intalado mapserver y ya descargue de aqui http://sourceforge.net/projects/kmlmapserver/ el kmlmapserver. Ahora estoy a la deriva, ayuda please.

    Molto grazie.

  • Welton

    Dear developer,

    I got pretty happy since I’ve found your website. KML’s great!!! I’d like to give it a try and to do so I’ve installed KML Mapserver service under MS4W package – http://www.maptools.org/ms4w/index.phtml. However, I don’t have any valid mapfile example to see how it works with Google Earth. I wanted to see examples of how the layers need to be set in order to access Google Earth’s Services.

    Congratulations! I look forward to read your answer.

    Welton

  • Alessandro Pasotti

    @Welton

    I’m not sure about how to help you. KML MapServer should work without any particular layer setup with most common layer types (point, line, polygon and raster).

    If you’re seeking help about mapserver (and mapfile) setup you should ask in the mapserver-users mailing list:

    http://lists.osgeo.org/mailman/listinfo/mapserver-users

    Just keep in mind that, in order to work, KML MapServer needs a working mapserver and php_mapscript installation, and a working mapfile. Before trying KML mapserver make sure your mapfile is working correctly.

    Hope it helps.

  • Welton

    Hi, thanks for your prompt answer.

    I’m not sure if was clear enough. I was thinking KML Service would help to bring together maps retrived by regular layers (described in the mapserver mapfile) and “special” layers (also described in mapserver mapfile) that would retrived data+maps from Google Earth. So, through the same mapfile I’d be able to see maps rendered by local layers + Google’s layers without any other direct implementation to access Google’s API. Did I get it wrong or this is it?

    I have some experience with mapserver but I was wondering if there was something that could help me to bring Google’s maps into my application without changing the front-end a lot.

    Thanks again.

  • Alessandro Pasotti

    @Welton

    No, KML MapServer is about serving KML from standard MapServer layers, you can also see it as translator layer between mapserver and google earth that adds KML output to mapserver.

    If there is something in the docs that could be misleading regarding what KML MapServer does, please let me know (I’m not an English speaker, so forgive me if I was not clear enough).

    Regarding your last point, I think that openlayers let you bring together several map providers (like google maps) in a single webgis 2D interface.

  • Welton

    Hi Alessandro,
    Thanks, you helped me indeed. Anyway I’m gonna take a deeper look at the docs and see if it serves my purpose. As I said I’m looking for something that brings Mapserver’s layers + Google’s layers (Earth and/or Maps) together using me same application without having to change it.
    By the way, your english is quite good. Thanks a lot.
    Welton

  • Lionel

    Hi Alessandro. I ‘ve played a lot with your kmlservice. Thanks a lot, it’s very usefull to publish easyly information in GE from Mapserver. I have a problem and perhap’s you can help me.
    Points in my postgis database have the following coordinates :
    POINT(-54.1349307585359 5.35234816882875)
    And published with kmlservices :
    54.13493059855571,5.352348023290587,0

    so the minus has desapeared !
    I have the same with polygons. :
    MULTIPOLYGON(((-54.1575773002721 5.37481412072896,-54.1125144353665 5.37504584594057,-54.1122858647611 5.32988039295894,-54.1573454337436 5.32965062576395,-54.1575773002721
    5.37481412072896)))

    becomes with kmlservice output :

    54.15757730027205,5.374814120728962,0 -54.11251443536646,5.375045845940568,0 -54.11228586476116,5.329880392958938,0 -54.15734543374361,5.329650625763946,0 -54.15757730027205,5.374814120728962,0

    (only the first point x coordinate is concerned).
    Thanks for help

    Today I am trying to run KML Mapserver to my working MapServer machine…

    I always got error message below. Is there anyone know what it is?
    —–

    Parse error: parse error in \ms4w\Apache\htdocs\kmlservice.php on line 1541

  • Daniel

    Hi,

    Now I see. I downloaded the code from SVN. the file structure is as below.

    kmlservice.php
    LICENSE.htm
    README.htm
    CHANGELOG.htm
    cache
    classes
    doc

    I am not familiar with PHP but I am trying to setup this service in my current working MapServer. So the above files/folders where I should put? I guess it is under ms4w/Apache/php, is that correct? Is there anythink I should look into?

    Thanks,

    Daniel

  • Alessandro Pasotti

    @Daniel

    yes, as stated in the README, you just put the folder tree under your document root and it should work.

    For generic help on PHP please refer to the thousands of forums and discussion boards available on the net.

    BTW we are available for commercial support in case you need it.

  • Daniel

    I got error message below. I am sure I have php_mapscript.dll in that folder….sorry to bother you….

    Hi,

    I am not able to configure it. Can you please tell me where do I unzip the KMLServer files? The Readme does not have any information. For the following request
    http://localhost/cgi-bin/kmlserver/kmlservice.php?map=india.map

    I get the following error
    The server encountered an internal error or misconfiguration and was unable to complete your request.

    Please contact the server administrator, admin@local.domain and inform them of the time the error occurred, and anything you might have done that may have caused the error.

    More information about this error may be available in the server error log.

    Please Help!

  • Selly

    Non si tratta di supporto commerciale, è una semplice domanda, se non vi va di rispondere prendo nota e cambio direzione. Ho mandato l’esempio visto che voi di esempi non ne date.

    Grazie comunque

  • Alessandro Pasotti

    @Selly
    non si tratta di “ci va” o non “ci va” di rispondere, kmlmapserver è open source e gratuito, il supporto invece si paga.

    Se avesse letto la documentazione si sarebbe accorto che con le limitazioni indicate, kmapserver lavora con qualsiasi mapfile “out-of-the-box” quindi senza nessun particolare accorgimento a parte quelli indicati.

    Per i dettagli e gli esempi sui mapfile, non è a noi che deve chiedere ma semmai alle innumerevoli liste che si occupano di mapserver.

    Cordialmente.

  • DESHOGUES Arnaud

    Ciao Alessandro.

    I’m a student in Master PRO specialised in GIS: Master SIGMA from Toulouse.

    I’am actualy on my training period where i’am working on a Web GIS application. My data base are based on postgresql/postgis and my webserveur is naturally Mapserveur.

    I have develop a map file using pmapper environment and I would like to put my data on G.Earth or G.Maps with your kmlservice.

    I have a problem and perhaps you can help me.
    I have make my map file using your indication but when I make the URL I’ve got a doc.KML without informations, just an info windows with the name of the layer insert on the URL.

    Thanks for your answer

    If you don’t mind i could make for you the French traduction for your web page and develop a tutorial.

    Congratulation

    Arnaud :p

    Dear Sir,

    I want to use it into C# asp.net.Is it possible.If it is possible?I am developing Mapserver with C#.I want to use KML.If it is possible Please guide me.

    I am waiting for your gret response.

    Thanks and Reagrds
    Venkat.

  • Agnar Renolen

    Just tested kml-map-server, and I have found a bug:
    KML-mapserver does not class layer expressions that use regeular expressions in the Map file, such as:

    LAYER
    …
    CLASSITEM ‘myattr’
    …
    CLASS
    …
    EXPRESSION /regex/
    …
    END
    END

    KML-Map-server simply returns all items within the source layer source ignorting the class expression.

  • Alessandro Pasotti

    @Agnar

    your statement is not true: kmlmapserver takes into account *only* regexes in class expressions (with some known limitation as written in the article and in the README).

    This does’nt mean that there could be a bug in the code, so you have two options now:

    * provide more detailed informations about this could-be bug and a provide a test case in order to allow us to reproduce the bug and fix it (the right place for bug report is : http://sourceforge.net/tracker/?group_id=206335 ), in any case we are very busy at the moment and this bug will not be examined before Q2 2009
    * fix the bug yourself (preferred option) and send us the patch

    Regards.

    Hi Alessandro,

    Congrats for good thought and efforts for mapserver users.
    I have configured on my local system. I have multiple Apache servers running on it. I use Port 84 for the MS4W application. I am using UTM coordinates and not decimal, degrees for my mapserver.

    Problems I face as follows.
    1. When it generates KML file it still considers port 80 as follows
    2. I am unable to see my line (Proposed Route) as per my shape file on the google earth.

    Thanks in advance for your help.

    Jitendta

    My KML file as follows

    Hi,
    I use ms4w for some time, I am very interested in the kmlmapserver, however after I release the kmlmapserver package and place it under ms4w\Apache\htdocs, and call the url “http://localhost/kmlmapserver-0.5/kmlservice.php?map=/ms4w/apps/ms_ogc_workshop/service/zz.map&typename=provincelocal” there is a http 500 erro, and a popup dialoge box says”CGI/FastCGI”problem, I do not know why.
    Thanks and Regards!

  • David Askov

    Congratulations on building such an easy tool. I have placed field values in my RESULT_FIELDS and DESCRIPTION_TEMPLATE, but cannot figure out a way to include field values in my balloon templates. Is this possible?

    I was thinking something like this:
    BALLOON_TEMPLATE “Deaths: %CONFIRMED_DEATHS%”

    Here is a bit of a WFS response for the layer:
    USA
    Georgia
    1
    0
    0
    406

    thanks!

  • David Askov

    My WFS response (with XML) got whacked when the form was submitted. The point was that there is a field called “CONFIRMED_DEATHS” coming from the WFS feed.

  • Alessandro Pasotti

    @David,

    You need to put “%” fields in DESCRIPTION_TEMPLATE, then put $[description] somewhere in BALLOON_TEMPLATE, kmlmapserver will first substitute “%” fields in DESCRIPTION_TEMPLATE, then substitute $[description] in BALLOON_TEMPLATE with the results of the first substitution.

  • Arnaud

    Hi,

    I’m trying to use your KML Map Server class.

    Everything works fine when I specify a typename paramater like in this URL :

    http://MyServer/kmlservice.php?map=/MyMap.map&typename=MyLayer

    The return is an XML file with all the objects inside.

    When I use it whith no typename parameter the XML file look like this :

    zones_sfr
    1

    http://localhost:80/kmlservice.php?map=/MyMap.map&typename=zones&request=kml&encoding=ISO-8859-1

    cellules_sfr
    1

    http://localhost:80/kmlservice.php?map=/MyMap.map&typename=cellules&request=kml&encoding=ISO-8859-1

    But when I use in Google Earth the server icon is always red. Like he can’t dynamically load the XML.

    Do you know what I’m doing wrong?

    Best regards

    Arnaud

  • Alessandro Pasotti

    @Arnaud,

    localhost ?

    Sorry if I’m too rude, but your question indicates such a low knowledge of the web and it services that I strongly suggest you to hire a professional or to invest some more time studying.

  • Vincent Bonnal

    Hello,
    I want to use KML Mapserver but I need to control the file name generated by KML Mapserver. By default, the file name is doc.kml (or doc.kmz). Is there an hidden parameter for that 😉 ?
    Thank you for this component !

  • Vincent Bonnal

    Thank you for your answer Alessandro.

    It was not too complicated …
    I added a parameter “kmxfilename”, I changed get_request () to read it and I changed send_header () and send_stream ().
    Everything is ok!
    Thank you for this script.

  • Lionel

    Hi,
    I try to use kmlmapserver with GoogleEarth v5.1.
    I still work with Google v4.2, but I have troubles with the last version. Polygons are not correct and points are not correctly represented (all points have the same coordinates).
    Have you heared about changes in KML specifications that could append with kmlmapserver ?

  • Alessandro Pasotti

    @Lionel:

    yes we have indeed had some problems due to a KML spec change (KML parser has become more strict), we have done some changes in our other internal libraries but we didn’t find the time to fix kmlmapserver.

    I received a patched version three days ago but I don’t know if this version fixes your problem, if you have time to work on this issue and if you are willing to commit back your findings I could send it to you for testing.

    Also: are you sure the problem is not in your Google Earth build ? I’ve observed a similar issue under a 64bit linux distribution and it was just a library problem.

  • Mwaura

    Thats a very fine application,thanks.

    I am using Mapserver data from a postgis database.When i use the script it servers a doc.kmz file alright but opening it in google earth it seems there is no data inside.The file is 4kb.
    Could anyone please give me a hint on what could be the problem.

    Hi there, I’ve got a working MapServer installation with both WMS and WFS running happily. I’ve installed KMLMapServer and it’s serving files. Which is great! However, the files only contain the layer names and not any data. I see a couple of other people are experiencing the same issue. Has anyone worked this one out yet?

    Is there any chance someone who has a working installation could post their map file?

    Thanks

    @Adrian,

    Since the development of kmlmapserver mapfiles syntax has changed slightly, this is probably the reason why kmlmapserver does not very well with latest mapserver.

    And to tell you the truth, we will probably not invest much more time in this project. The idea behind kmlmapserver was to have something at hand while a true KML support was being integrated into mapserver core. This did not happen so far.

    Unfortunately, we have not any paying customer to fund the development of kmlmapserver and we did don’t receive any donation until now.

    If anybody has a budget available to invest on further tests and development on kmlmapserver, we would be happy to continue our work on this project.
