Finding nearest facility location with open box query using Geohashing and MapReduce

This paper gives an algorithm to find the nearest facility location using Geohashing. Open box query is implemented to find nearest location which is based on unbounded data. Searching is done based on the longitude and latitude of locations. Geohashing is a technique which converts the longitude, latitude pair into a single value which is represented in binary format. Data accumulated in Geospatial queries is too big in size. Therefore MapReduce framework is used for parallel implementation. MapReduce splits the input into the independent chunks and execute them in parallel over different mappers. Geohashing and MapReduce when fused together to find the nearest facility location gives very good results.
