The document summarizes the OpenLayers Mobile Code Sprint held from February 21-25, 2011 in Lausanne, Switzerland. Key accomplishments included developing controls for touch-enabled devices, improving performance of dragging and zooming, and creating mobile-optimized examples using Sencha Touch and jQuery Mobile. Over a dozen tests were conducted on various mobile platforms to test the new controls and optimizations. The code sprint helped advance OpenLayers for improved support of mobile and touch-enabled devices.

1. OpenLayers Mobile Code Sprint Summary 21.2.2011 – 25.2.2011 Lausanne - EPFL - Switzerland

2. Mobile compatible controls Description The OpenLayers controls work similarly on touch- and mouse-centric environments. Examples

3. Touch Navigation Control Description The navigation control handles map browsing with touch events (dragging, double-tapping, and tap with two fingers). Larger UI control. Examples Source code

4. Kinetic Dragging Description The kinetic dragging let the map smoothly brake after a drag. Examples Source code

5. Pinch Zoom Description Support pinch zoom in and zoom out (double finger touch) Example Source code

6. Anchor Permalink Control Description Place a permalink in the anchor of the url. Examples Source code

7. Geolocate Control Description Usage of the GeoLocation API to set or track the position of the mobile device Example Source Code

8. Performance Description In order to improve the drag action, OpenLayers now limits the pixel to map translations that occur during dragging. The performance improvement is really important. Previous release – Current release

9. Minimal Support for devices without touch support Description Minimal support of OpenLayers when the device has no touch capabilities. Blog - Mail Demonstration on Nokia E7 Demonstration on Windows 7

10. Examples Description Mobile compatible example list and specific mobile examples. Examples Mobile examples

11. Sencha Touch Example Description Demonstration of an application created with OpenLayers and Sencha Touch Example Source Code Base – Specific

12. JQuery Mobile Example Description Demonstration of an application created with OpenLayers and JQuery Mobile (…discover the origin of the 16 participants of the OpenLayers mobile code sprint) Example Source Code Base – Specific

13. Accelerometer Example Description The information about acceleration are presented for devices with accelerometer support (for now iOS 4.2+ and Chrome) Example

14. Unit tests Description Optimize unit tests to work with a built OpenLayers library and UI improvements to test on mobile devices Tests

15. Test Lab Description Dozen of tests have been done on various platforms Test Sheet

16. Browser detection Description Page used to identify the capacity and characteristics of the used browser. Allow to test the mouse and touch events. Example

17. Closure Compiler Support & Build Description OpenLayers can be built with Google Closure Compiler and this reduces the size of it. A specific mobile build has been created. CSS Tidy is now used for minifying the stylesheets. Google Closure Compiler Support Mobile Specific Build Link to mobile examples with http://m.openlayers.org/ CSS Tidy usage

18. Various ongoing developments – R&D Offline storage of features and tiles - Sandbox Mobile Layer Switcher – Ticket in review Editing Tool – Ticket in review
