Spatial Data Processing Library for Stratosphere

Stratophere is big data analysis platform which implements through parallel programming concepts. Stratosphere's programming model provides six parallelizable operator functions Map Reduce Join  Cross CoGroup Union JTS library is a standard java library to perform geographical analysis with special data types like points, paths, polygons. In this spatial data processing library, we are going to implement various geographical analysis such as intersections, joins with big map data in standard formats like OSM(Open Street Map) There is some effort in here to create new data types in stratosphere which is compatible with JTS library. Here is an example to Stratosphere Java API with WordCount example. You can simply download the stratosphere-examples and check it your own. When you need to familiar with stratosphere, there is exercises in bigdataclass website. You can find out those implemented exercises in java. Word Count examp
