Abstract
the revolution of technologies (social networks, smartphones, GPS and Remote Sensing Image) increase the volume of informations wich makes humanity in new need " Storage of huge volume of data ". the traditional strategy to store data become problem for humanity and then this need build new art to resolve this problems the " Spatial Big Data (SBD)" SBD store proncipally three types of data: vector data, raster data and network data. The complexity and nature of spatial databases make them ideal for applying parallel processing. This also emphasizes the need for developing new efficient geospatial analytic for analyzing spatial big data. So, we review the most used spatial data algorithms attracting human interests especially when the amount of satellite images continues to grow as more information becomes available. In this context, we propose a system based on Hadoop an open source system that implements the MapReduce programming model and that can improve the classification of large scale remote sensing image and benefit the power of spatial big data concept
