Update : 3/2018 AR enabled version with ARKit available here
Suprise, iOS 9 MapKit finally enables flyeover mode with WMS overlays ! I have used my github MapKit sample and only set in MapViewController mkMapView.mapType = MKMapTypeHybridFlyover;

WMS overlay on Windows 8.1 and Windows Phone 8.1
I agree with this blog “Learning how to use Maps in the .Net world is a never ending business. There are major API-differences between WPF, Silverlight, Windows 8 Store apps and Windows Phone and even between WP7 and WP8. Windows Phone 8.1 makes no differ and there are many breaking changes here”
my tests of previous WMS overlays are listed here:
Silverlight : https://blog.sumbera.com/2010/02/25/overlay-wms-on-silverlight-bing/
Windows Phone 7: https://blog.sumbera.com/2011/02/18/windows-phone-7-wms-test/
Windows Phone 8: https://blog.sumbera.com/2013/03/10/tiled-wms-overlay-in-windows-phone-8/
I have put together Visual studio 2013, Update2 Solution that does WMS overlay in Windows 8.1 and Windows Phone 8.1 called WMSonWin81 – here on github
Video of Windows Phone 8.1 below, used “Project My Screen App” to project the app on desktop and record.
WMSonWin81
WMSonWin81using universal app for Windows Store and Windows Phone Store apps Both apps do not share same namespace for map nor component. Windows Store is using Bing Map while Windows Phone is using map control as part of the WP8.1 framework located in Windows.UI.Xaml.Controls.Maps
there are main 2 projects:
WMSOnWin.Windows
Sample code of using WMS source on Windows Store Apps using Bing Maps:
MapTileLayer mapTileLayer = new MapTileLayer();
mapTileLayer.GetTileUri += delegate(object sender, GetTileUriEventArgs e) {
Rect mercBounds = GlobalMercator.TileBounds(new Tile(e.X, e.Y), e.LevelOfDetail);
e.Uri = new Uri(string.Format(_wmsUrl, mercBounds.Left,
Math.Abs(mercBounds.Bottom), mercBounds.Right, Math.Abs(mercBounds.Top)));
};
_bingMap.TileLayers.Add(mapTileLayer);
WMSOnWin.WindowsPhone
Sample code of using WMS on Windows Phone Store App using Windows.UI.Xaml.Controls.Maps; core class to look is HttpMapTileDataSource
HttpMapTileDataSource dataSource = new HttpMapTileDataSource();
dataSource.UriRequested +=
new TypedEventHandler<HttpMapTileDataSource, MapTileUriRequestedEventArgs>(
(source, args) => {
Rect mercBounds = GlobalMercator.TileBounds(
new Tile(args.X, args.Y), args.ZoomLevel);
args.Request.Uri = new Uri(string.Format(_wmsUrl, mercBounds.Left,
Math.Abs(mercBounds.Bottom), mercBounds.Right, Math.Abs(mercBounds.Top))); ;
});
_map.TileSources.Add(new MapTileSource(dataSource));
Tested on Windows 8.1 64bit, and Lumia 810, Windows Phone 8.1
enjoy.
Credits: got help here to repair problems with USB connection to my Lumia 810 (had to uninstall USB driver for the phone in device manager) and here to get WP8.1 on Lumia 810
WMS on MapKit with iOS7
Updated WMS over MapKit sample code for iOS7 , available on github I have added cadastral maps of Czech Republic, used camera API to set the view and tested, check also WMS on Google Maps SDK on iOS mentioned here
iOS7 introduced new class MKTileOverlay sample derives from this class WMSTileOverlay
Key method to custom tile loading (and cache control) is loadTileAtPath:result
- (void)loadTileAtPath:(MKTileOverlayPath)path result:(void (^)(NSData *tileData, NSError *error)) result
this method is called by MapKit (or better by MKTileOverlayRenderer ) when it needs to draw a tile . It asks for NSData (and error) from x,y,z tile coordinates. In this method you can load NSData either from local cache or from NSURLConnection and pass resulting NSData (when ready) back to MapKit, for example like this (reading from cache)
result ([NSData dataWithContentsOfFile:filePath], nil);
if you do not need to use cache and you do not provide loadTileAtPath method , you can use another hook (callback) that is provided by MKTileOverlay, URLForTilePath:path
- (NSURL *)URLForTilePath:(MKTileOverlayPath)path
this method enables to custom format URL required to load tile, thus you can use WMS HTTP-GET parameters, for example :
NSString * resolvedUrl = [NSString stringWithFormat:@"%@&BBOX=%f,%f,%f,%f",self.url,left,bottom,right,top];
if there is neither method in the derived class, then you probably do not need to derive at all from MKTileOverlay and directly use it with initWithUrlTemplate (not case for WMS, but for any other x,y,z sources)
Bad news is that MapKit on iOS7 doesn’t support tilt/pinch in Satellite/Hybrid mode in MapKit on iOS7
WMS with Google Maps on iOS
Sample for using WMS sources in Google Maps SDK for iOS. available on github here: https://github.com/Sumbera/WMS_iOS_GoogleMapSDK
Provide your API key in the WMSController.h
- Google Maps for iOS used : 1.7.2 (April 2014)
- used XCode 5.1.1 (April 2014)
- iPad Air, iOS 7.1 (should run in iOS6.0 too)
There are two ways of overlaying WMS in the Google Maps for iOS SDK:
“Method B”: use GMSTileURLConstructor
// -- method B. WMS tile layer with GMSTileURLConstructor
GMSTileURLConstructor urls =
^(NSUInteger x, NSUInteger y, NSUInteger z) {
BBox bbox = bboxFromXYZ(x,y,z);
NSString *urlKN =
[NSString stringWithFormat:@"Your WMS url&BBOX=%f,%f,%f,%f",
bbox.left,
bbox.bottom,
bbox.right,
bbox.top];
return [NSURL URLWithString:urlKN];
};
“Method A”: use custom TileLayer derived from GMSTileLayer
- your derived class from GMSTileLayer (here WMSTileLayer.h) will receive tile request
-(void)requestTileForX:(NSUInteger)x y:(NSUInteger)y zoom:(NSUInteger)z receiver:(id<GMSTileReceiver>)receiver - WMSTileLayer first checks for cached tile and if found calls :
[self drawTileAtX:x y:y zoom:z Url:urlStr Receiver:receiver] ;
- if tile is not cached we download it, save it to the file system (using MD5 hash) and call to draw it
[data writeToFile: filePath atomically:YES]; [self drawTileAtX:x y: y zoom: z Url:urlStr Receiver:receiver] ;
- drawTileAtX is very simple:
-(void) drawTileAtX: (NSUInteger) x y:(NSUInteger) y zoom:(NSUInteger)zoom Url:(NSString*) url Receiver: (id<GMSTileReceiver>) receiver { UIImage *image = TileLoad(url,NO); [receiver receiveTileWithX:x y:y zoom:zoom image:image]; }
}
both ways are used in this sample.
Tiled WMS overlay in Windows Phone 8
Update May 2014: version for Windows Phone 8.1 is here: https://blog.sumbera.com/2014/05/23/wms-overlay-on-windows-8-1-and-windows-phone-8-1/
Looking on Windows Phone 8 Map SDK, I have tried to migrate a simple WMS overlay from Windows Phone 7 (Bing map) – blogged here : https://blog.sumbera.com/2010/11/07/tiled-wms-overlay-in-windows-phone-7/
Changes :
– for migration you have to add before migration System.Core into the project (had to edit manualy proj file and add it there)
-Change from *.Controls.Map to *Map.Controls
– XAML definition
<maps:Map x:Name="sampleMap" LandmarksEnabled="False" Loaded="sampleMap_Loaded" CartographicMode="Hybrid" Center="49.320574,16.68942" ZoomLevel="14" />
Loading TileSource:
private void sampleMap_Loaded(object sender, RoutedEventArgs e)
{
MapsSettings.ApplicationContext.ApplicationId = "<applicationid>";
MapsSettings.ApplicationContext.AuthenticationToken = "<authenticationtoken>";
TileSource wmsTileSource = new WMSTile();
sampleMap.TileSources.Add(wmsTileSource);
}
..then in your TileSource you can use as usual your method GetUri.
Sample code based on Microsoft Sample can be downloaded here: www.sumbera.com/lab/WP8/WMSonWP8.zip
WMS overlay in iOS MapKit
update May 2014: iOS7 version and notes available here: https://blog.sumbera.com/2014/05/17/wms-on-mapkit-with-ios7/
I have crafted really simple and quick code at ESA App dev camp for viewing WMS sources. And as few people questioned me on how to do this, I am posting the full code of the MapView component that takes sample WMS service (Ozone) and overlays this above MapKit.
In github here : https://github.com/Sumbera/WMSoverMapKit
you will find MapViewController that accepts WMS sources stored as array with BBOX %f, %f, %f, %f
-(void) addWMSOverlays: (NSArray*) overlays
this can be called from your rootController:
MapViewController * mapViewController = [[MapViewController alloc] init]; WMSOverlay * wmsOverlay =[[WMSOverlay alloc] initWithName:@"Ozone" Url:@"http://wdc.dlr.de/ogc/produkt_t?LAYERS=GOME2_O3& TRANSPARENT=TRUE& FORMAT=image/png& STYLES=& SLD=http%3A%2F%2Fwdc.dlr.de%2Fsld%2FGOME2_O3_sld.xml& TIME=2012-02-12T00:00:00Z& SERVICE=WMS& VERSION=1.1.1& REQUEST=GetMap& SRS=EPSG:4326& WIDTH=256& HEIGHT=256" Opacity:0.5]; [mapViewController addWMSOverlays:[NSArray arrayWithObjects:wmsOverlay, nil]];
please note:
#1. that sample code uses experimentaly MKNetworkKit, which has some occasional troubles. You can replace the download method in WMSOverlayView class downloadTile
#2 it uses simple hash for storing tiles on cache.
enjoy
iKatastr rocks !
This is somehow very encouraging
#1 iKatastr is still on top in the category Navigation in Czech app store after 4 months ! on iPhone it keeps 2nd place right after Mapy CZ provided by largest internet search in CZ Seznam. On iPad, however, iKatastr is still 1st in category Navigation.
#2 Users of iKatastr has reported quite lot positive feedbacks, see here : http://appcomments.com/app/id396352287/iKatastr_reviews?country=143489&show=show_all_comments&sort=sort_recent&sortorder=sort_ascend&page=1
#3 IKatastr has been mentioned in Czech magazine “Mobility” 1/2011, on page 85.
Quoted from the magazine press:
“There are just few high quality applications in the Czech App Store. Even fewer of them are for free.
iKatastr developed at Mendel University in Brno belongs to this narrow group with functionality that is also unique in the international comparison. “
Windows Phone 7 and WMS test
Update #1 13/03/2013, here is new blog about Tiled WMS overlay for Windows Phone 8 :https://blog.sumbera.com/2013/03/10/tiled-wms-overlay-in-windows-phone-8/
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: https://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.
Update #2 Reviewing this after 2 years (March / 2013), – something went wrong with this estimation, but do you remember Gartner predictions from that time ? for example here : http://www.globalnerdy.com/2012/05/07/the-windows-phone-predictions-that-idc-gartner-and-pyramid-research-probably-hope-youve-forgotten/
but we are not yet in 2015, so we will see.
Update #3 02/2016 : this estimation was completely wrong , Windows Phone platform is nowhere, looks like great lesson learned – even you own great language and framework (C# and .NET) there is nothing that guarantees you being successful on emerging/disruptive platform/form factor. Objective-C (then Swift) or Java on Android got this mobile cake.

OpenLayers or GoogleMap v3 for mobile web app ?
[2014 January] UPDATE : new Openlayers 3 beta 1 works quite well on iPad as well as Laeflet 0.7, check post here: https://blog.sumbera.com/2014/01/23/leaflet-0-7-vs-openlayers-3-beta-1-on-ios/
[2011 September] UPDATE : new Openlayers 2.11 works quite well on iPad/iPhone.
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
