Hi Sarthak Can you provide us more info about your programming background (languages) and to any work/project you did with open source geospatial software?

I also recommend to have a detailed look at:
https://wiki.osgeo.org/wiki/Google_Summer_of_Code_Recommendations_for_Students <https://wiki.osgeo.org/wiki/Google_Summer_of_Code_Recommendations_for_Students>
and a look at how past proposal are structured. The student is suppose to compile a complete proposal including a detailed timeline.

you can find a black of the reports at:
http://epinux.com/OSGeo-live/osgeolive-gsoc-2015/Report/ <http://epinux.com/OSGeo-live/osgeolive-gsoc-2015/Report/>

The main coding-part of the GSoC-2015 idea focus on the development of a js widget to render and interact geospatial data within a notebook.
Cesium-js has been chosen as map-canvas, so most of the development will happen on the cesium widget code but the same code-concepts apply with any other js-map canvas. Essentially what is needed is a “bi-directional communication” between python and js (which is performed using the ipywidget library).

There are unresolved issue that you can start with.
The first basic one is to have the cesium-js mouse action and camera parameters sending back information to the python kernel.

see this issue:
https://github.com/petrushy/CesiumWidget/issues/17 <https://github.com/petrushy/CesiumWidget/issues/17>

To test your skill:

essentially what is needed is a global variable say:“camera view” 
where info about the camera status [lat, lon, roll, pitch, heading] are stored

From python we want the functions ```zoom_to``` and  ```fly_to``` to use this variable to update the camera status

and we also want update the same variable “ camera view” 
each time the status of the camera will change (from the js side, eng: each time the user will pan, zoom etc .. the cesium globe)

Hope it make sense, feel free to mail me, add comment on the github issue or join us on irc.

Note: there is an other student which already showed interest in the same project, he/she is in cc to this mail.

Thanks,

Massimo.
