Hey Shashika,
Stratosphere has been renamed to Apache Flink while we entered the Apache Incubator. We are now using a new mailing list on [hidden email]. I please subscribe to dev@flink by sending an (empty) email to [hidden email]. I think adding a spatial data processing library on top of Flink is still a very interesting project.

Hi Robert and all,
It was great to hear that you entered the Apache Incubator as 'Apache Flink'. I already subscribed the mailing list and got some mails about updated Scala API. I need to contribute to spatial data possessing library where I stopped. Those days I really studied on this and if I don't do anything, it will be a wastage for me. So help me, how I start this again On Fri, Sep 12, 2014 at 6:03 PM, Robert Metzger <[hidden email]> wrote: > Hey Shashika, > > Stratosphere has been renamed to Apache Flink while we entered the Apache > Incubator.

Hey!
Nice to hear back from you. I would suggest that you try and familiarize yourself with the new setup and the current state of the system. Here is also a guide with some first steps in contributing: http://flink.incubator.apache.org/how-to-contribute.html A geospatial library still sounds great. How exactly are you imagining it? A set of types and operations/algorithms? Or something more integrated?

Hi Stephan and all,
I'll setup the new system and familiar with it. Fabian already has efficient JTS data types for manipulate Geo-spartial data. Hope to implement features gradually. 1) Implement a code to read OSM(open street map) data and GPS log traces. 2) As the first step, implement to find a geo-location to what region it belongs to.
