 Posted: Thu Jan 24, 2008 8:53 am Post subject: UMap Providers |
 |
|
One of the greatest features in our brand new UMap component is the Provider class. This class handles map types, tile layers and the loading of external resources: settings, language and copyrights. You can create Provider subclasses to create custom tile provider services and add you own map types.
By default UMap uses GoogleProvider class that represents Google tile service. GoogleProvider also uses our site for settings.xml file, langugage and copyright proxy scripts. If you don't want UMap to connect to our server you can change the urls GoogleProvider uses, so that it will connect to your server instead. Please be aware that you should update the map version, and all the paths manually if anything changes.
Here is a simple example:
| Code: | import com.afcomponents.umap.core.UMap;
import com.afcomponents.umap.providers.google.GoogleProvider;
// create map and attach it to stage
var map:UMap = new UMap();
map.setSize(stage.stageWidth, stage.stageHeight);
this.addChild(map);
// define GoogleProvider with custom paths
var settings:URLRequest = new URLRequest("http://umap.s3.amazonaws.com/assets/xml/GoogleSettings.xml?rand=" + Math.random());
var language:URLRequest = new URLRequest("http://maps.google.com/maps?file=api&v=2")
var copyright:URLRequest = new URLRequest("http://www.afcomponents.com/proxy/g_map_as3/copyright.php");
map.setProvider (new GoogleProvider(false, settings, language, copyright)); |
Here are the details on each path:
1. settings.xml file - describes the map types that should be implemented with the provider. You can see the content of this file on our server: http://umap.s3.amazonaws.com/assets/xml/GoogleSettings.xml
| Code: | <GMap>
<logo>http://umap.s3.amazonaws.com/assets/img/GoogleLogo.png</logo>

</GMap> |
2. language - is a file that contains the map language data. It is a regular google maps api file, that is loaded by javascript map api. We use a special proxy that let's you load this api with different language setting. You can pass your request through your proxy to Google: http://maps.google.com/maps?file=api&v=2. If you want to embed your Google API key, you can add it to this link &key=my_google_api_key, but I don't believe it is necessary. Here is a sample .php proxy:
| Code: | <?php
include('http://maps.google.com/maps?file=api&v=2&key=my_api_key');
?> |
3. copyright - is a special proxy that redirects the copyright request to Google server. Here is a sample .php proxy file that you can use on your server:
| Code: | <?php
include('http://maps.google.com/maps?spn='.$_GET['spn'].'&z='.$_GET['z'].'&vp='.$_GET['vp'].'&t='.$_GET['t']);
?> |
Please feel free to post your questions, bug reports and ideas in this thread.

The copyright URLRequest doesn't work.
Always it accesses to AFC server...
I checked it via HTTP Live Headers of FireFox addon. |

This is an example. Now it is possible to do such nice things thanks to Fine UMAP AS3! This is our Hybrid.Map tile from Mapinfo (Arcinfo, etc.) and Satellite Google.Thanks AFC. This is a revolutionary idea!!!
Here an example

|

following the example above add this map type to your own settings file
| Code: | <mapType>
<name> terrain </name>
<textColor> 0x000000 </textColor>
<linkColor> 0x7777CC </linkColor>
<layer>
<minZoom> 0 </minZoom>
<maxZoom> 17 </maxZoom>
<url><![CDATA[ [server]/mt?n=[n]&v=[version]&x=[x]&y=[y]&zoom=[zoom] ]]></url>
<version> w2p.64 </version>
<servers>
<url> http://mt0.google.com </url>
<url> http://mt1.google.com </url>
<url> http://mt2.google.com </url>
<url> http://mt3.google.com </url>
</servers>
</layer>
</mapType>
|
add the custom provider and set the map type to "terrain"
this example is running locally so I use a relative path for the settings file
| Code: | import com.afcomponents.umap.core.UMap;
import com.afcomponents.umap.providers.google.GoogleProvider;
// create map & attach it to stage
var map:UMap = new UMap();
map.setSize(stage.stageWidth, stage.stageHeight);
this.addChild(map);
//define GoogleProvider with custom paths
var settings:URLRequest = new URLRequest("settings.xml?rand=" + Math.random());
var language:URLRequest = new URLRequest("http://maps.google.com/maps?file=api&v=2")
var copyright:URLRequest = new URLRequest("http://www.afcomponents.com/proxy/g_map_as3/copyright.php");
map.control.provider = new GoogleProvider(false, settings, language, copyright);
// set map type
map.setMapType("terrain"); |
enjoy! |

|
|
| Valdamir, your example above is very interesting! I took a look at your settings.xml file and I don't see anything about a gis tile server. I looked at the http headers and I can see that you're loading your own tiles. How do you accomplish this? Is it an overlay? Can you please post some example code so others can try to load in their own tiles or GIS data in the same manner? Thanks. |

I would like to add my own maps, which at the moment are vector layers in Illustrator. I would really like to use them as swf's an somehow geo-reference them.How would we bring these into this whole context? When can we see more on this? Tutorials, descirptions? Do we need a copy of arcGIS 9.2. or are there other ways to do it?
Any guides to reading is appreciated |

Vladimir
Thank you for the link. The question remains, what is the production process. What is necessary to provide own maps. (ArcGis Desktop? Server???)
Or even better, is it possible to exchange the boring polygons with swf overlays that behave just like they were map layers?
I appreciate your offer doing a test for (I will send you some stuff by mail soon) but we are in an evaluation process and need to make decisions based on things we understand and do ourselves. So it's important to see examples and understand exactly how they work and are processed.
There is something else that makes me curious. This morning I was able to see both, Google's and your content, now it seems that all Google content rendered with afcomponents is beeing blocked. Why is this? Can this be avoided? |

|
|
Hi all,
I have been looking in both threads and I cant find an answer, so here it goes.
-Are you planning to support WMS as a Tile server? I think this should not be difficult, I have a working gmap with Javascript doing the same.
-Do you plan to create a very simple Provider just to overlay images over the map. I have seen implementation of this in Javascript. It seems pretty simple and is a very nice functionality 
Thanks for the great work... it is really amazing...
Javier. |

What it is the WMS you have mentioned?
We will think of creating a simple Provider for you.
