Windows Phone 7 and WMS test

By Stanislav

   I have quickly tested my new Windows Phone 7 (Samsung Omnia) device with the Czech cadastral map WMS overlay over the BingMaps and DeepEarth (also see this blog here: http://blog.sumbera.com/2010/11/10/wms-overlay-on-bing-maps-vs-deepearth-on-wp7/) . if you are familiar with www.ikatastr.cz and iPhone version of it (iKatastr) than this example is using same data sources.

In short : it was a great experience – WP7 was smoothly  registered, automaticaly connected to internet even without  a SIM card using USB cable and Visual Studio 2010 integration just works perfect (so far:) In comparison to many difficulties and ‘certification hell’ on iPhone this is a great relief. Now giving the fact that Nokia is going to support and develop Windows Phone 7, great user experience with WP7 and (for me and menay others) great development experience, this might change the mobile landscape significantly over the 1 or 2 years.

I will guess here that WP7 platform will exceed number of iPhone applications in less than 2 years.

XenApp6 trial installation troubles notes

By Stanislav

Here are few notes on installing XenApp6 on Window Server 2008 R2 .

-1 used guide : http://www.danieletosatto.com/wp-content/uploads/2010/04/howto_install_configure_xenapp6_server_with_webinterface_license_server.pdf

0. I had troubles with IIS not able to start, installing IIS roles before XenApp6 solved the problem

1. follow the guide until “License Server Configuration” screen, I havn’t used XML Service IIS integration (as using this in my previous attempt coused IIS troubles mentioned in step 0.

2.  generate trial license : http://carlwebster.com/blogs/webster/archive/2009/01/03/Learning-the-Basics-of-XenApp-5-for-Windows-Server-2008-Part-1-of-7.aspx

3. upload license to the XenApp 6 here : http://zenapp.blogspot.com/2010/04/installing-xenapp-6-part-3-citrix.html

4.configure XenApp6. (continue with the guide in #-1)

5. Publish application

6. in Citrix Web Interface Management create new XenAppService Site -> this will create PNAgent

7. Donwloaded client plug-in 12 for windows 64 bits

8. Manualy set up script folder  http://support.citrix.com/article/CTX125107

9. Changed the pool for Script (CtxScriptPool) to enable to run 32bit applications http://forums.citrix.com/thread.jspa?messageID=1531112

10. Citrix plug-in client (finally) works

11. Changed the pool for Script (CtxAdminPool) to enable to run 32bit applications (WI now works too  used the standard port 80)

Android vs iPhone development

By Stanislav

this is interesting comparison of OS versions runing on Android and iOS and ‘developer friendly environments’ from the SDK perspective:
“The number of devices per OS is a great marketing number for Google and Apple to fight over but as a developer—who wants to get the most out of the SDK—I care about the version of the OS on the devices. If I want to use the latest and greatest SDK’s I’ll take Apple’s 80% of 21% over Google’s 30% of 28%.”

http://jeffreysambells.com/posts/2010/05/20/android-vs-iphone-development-decisions

“The iPhone has another big advantage and it solves the problem of distribution as I alluded to earlier. iPhone users use iTunes to sync their devices and add content. The process of syncing the device also checks for updates and allows all iPhone OS devices (iPhones, iPod Touches, iPads) to download the latests version of the OS. As a result the March 2010 iPhone Platform Versions stats look very developer friendly”

“More than 50% of the Android install base is still using version 1.6 or less. As a developer what should I do? If I choose to take advantage of the latest and greatest SDK I get less than half of the devices! But still, the bigger problem is there is no clear and easy upgrade path for those bottom 50% to get the newer OS version”

SVG map sample and Canavas in OpenLayers

By Stanislav

SVG map sample : http://cartagen.org/

Canvas map sample : http://trac.osgeo.org/openlayers/wiki/Future/OpenLayersAndHTML5

Thesis on Canvas and Open Layers (August 2010)  ”Evaluation of HTML5 for its Use in the Web Mapping Client OpenLayers” : http://erwin-sauerwein.de/tobias/Tobias%20Sauerwein%20-%20Evaluation%20of%20HTML5%20for%20its%20Use%20in%20the%20Web%20Mapping%20Client%20OpenLayers.pdf

OpenLayers with Canavas  (partialy deprecated) http://trac.osgeo.org/openlayers/wiki/Future/OpenLayersWithCanvas

SVG vs Canvas comparison by Jeffrey Warren from : http://unterbahn.com/2009/08/svg-vs/

“Well, SVG doesn’t scale well to large numbers of objects, but Canvas doesn’t
scale well to large screens”

“SVG performance degrades quickly (exponentially on Safari?) in the number of
objects, but Canvas performance remains at a near-constant low. This makes
sense, since Canvas is just a bitmap buffer, while SVG has to maintain
additional references to each object that it renders. Also, though not pictured,
note that performance in clearing an SVG element also decreases in the number of
drawn objects.”

OpenLayers or GoogleMap v3 for mobile web app ?

By Stanislav

I have experimented with OpenLayers 2.9 using touch.js extension for capturing touch events from iPhone/iPad. Although stripped down version of OL is about 184KB, the performance is very bad. If you have iPhone/iPad check this experiment: http://www.sumbera.com/lab/iphone/katastr.htm (note it will not work from desktop browser)

 OL team is working on v3 of OL to be more lighter, faster even for mobile devices, see here: http://trac.osgeo.org/openlayers/wiki/three  or here : http://openlayers.org/blog/2010/06/30/openlayers-3-on-github/

 Meanwhile I have tested new GoogleMaps v3 how it works on iPhone/iPad. despite few problems (stability, problems with cached tiles or disconnected JavaScirpt  to load new tiles -iPad)  it works pretty well . Check yourself this page from your mobile touch device (iPhone.iPad,Android): http://www.ikatastr.cz/iKatastrM.htm

Conclusion : Google Maps v3 wins on mobile over the Openlayers 2.9

 

[2011 September] UPDATE : new Openlayers 2.11 works quite well on iPad/iPhone.

Tiled WMS overlay in Windows Phone 7

By Stanislav

  This post [http://blog.sumbera.com/2010/02/25/overlay-wms-on- google-in-silverlight-bing/ ] talked about how to overlay over the Bing maps Silverlight control Google tiles  and tiled WMS. It was quite easy to port this web sample into the Windows Phone 7 emulator. I took a smaple code from Training kit called “Ex1-TheBingMapControl” and extend it with the 2 classes : GoogleTile and WmsTile, with slight changes to the namespace using Microsoft.Phone.Controls.Maps (original for Silverlight was  Microsoft.Maps.MapControl). Then extend MainPage.XAML with :

                    <my:MapTileLayer Opacity=”1″>
                        <my:MapTileLayer.TileSources>
                            <local:GoogleTile></local:GoogleTile>
                        </my:MapTileLayer.TileSources>
                    </my:MapTileLayer>
                    <my:MapTileLayer Opacity=”1″>
                        <my:MapTileLayer.TileSources>
                            <local:WMSTiledOverlay></local:WMSTiledOverlay>
                        </my:MapTileLayer.TileSources>
                    </my:MapTileLayer>
 
 

Extended sample code availabel for download here : http://www.sumbera.com/lab/wp7/TheBingMapControlWithWMSandGoogle.zip

 Update: I found the way calculating BoundingBox from the quadkey somehow limiting (the DeepEarth weay) since it worked only till the level 18. So here is updated class fro getting correct bounding box of the tiled WMS request in the Bing Silverlight control:

            public static double TileToWorldPosX(double tile_x, int zoom) {
                return  (float)((tile_x / Math.Pow(2.0, zoom) * 360.0) – 180.0);
            }
            public static double TileToWorldPosY( double tile_y, int zoom) {
                double n = Math.PI – ((2.0 * Math.PI * tile_y) / Math.Pow(2.0, zoom));
                return   (float)(180.0 / Math.PI * Math.Atan(Math.Sinh(n)));
            }
            public override Uri GetUri(int tilePositionX, int tilePositionY, int tileLevel) {
                int zoom = tileLevel; //SSU tileLevel would be same as zoom in Bing control
                double deltaX = 0;// 0.00135; //SSU deltaX for SLP WMS
                double deltaY = 0;// 0.00058; //SSU deltaY for SLP WMS
                double minXLon = TileToWorldPosX(tilePositionX, zoom) + deltaX;
                double minYLat = TileToWorldPosY(tilePositionY + 1, zoom) + deltaY;
                double maxXLon = TileToWorldPosX(tilePositionX + 1, zoom) + deltaX;
                double maxYLat = TileToWorldPosY(tilePositionY, zoom) + deltaY;
                string wmsUrl = string.Format(this.UriFormat, minXLon, minYLat, maxXLon, maxYLat, 256);
                return new Uri(wmsUrl);
            }
        
        }
