The Ministry of Land, Infrastructure and Transport (MoLIT) will develop Hadoop for spatial big data collection, storage and analysis as the first in the world. Spatial big data Hadoop, which will be developed with domestic technology, has only been studied and does not have any actual application cases across the world. It is forecast that the private sector will also be able to create various business items using national spatial information based on the spatial big data Hadoop.
MoLIT announced on the 1st that it would develop Hadoop to analyze spatial big data as part of a spatial big data system implementation project. The plan is to set up spatial big data Hadoop application system targeting MoLIT by the end of this year and to apply it to government-wide spatial big data system next year. From 2017, spatial big data Hadoop will be used in public service and then the system will be provided for usage to the private sector.
Hadoop is a technology to process large-sized data by combining several low-end computers into a single unit. The advent of Hadoop led to accelerating big data analysis. However, the existing Hadoop technology had been able to collect, store and analyze only two-dimensional big data, such as texts and images. It was limited in analyzing three-dimensional spatial big data.
The development of spatial big data Hadoop was initiated with a proposal by FORCEWAVE, a small-scale company in Korea. MoLIT anticipates that this technology will enable various data analyses using urban spatial information. Based on continuous cadastral maps, aerial photographs and 3D images, it can also lead to creating public services through convergence with administrative information, such as about population, income level, climate, transportation and logistics. In addition, using Hadoop, which is developed as the first in the world, a government-wide platform to provide overall governmental spatial information will be developed.
Economic effects are also anticipated according to the global spatial big data market domination. Using spatial big data Hadoop developed with domestic technology, the industry can enter overseas markets and create various business models. “By February, we will establish an overall plan including spatial big data Hadoop development,” said a MoLIT source. “Afterwards, we will commence development full scale.”
The spatial big data system implementation of MoLIT is a project to build an infrastructure for convergence of spatial information owned by the government with administrative information and information from the private sector. Through this project, a linked data collection and storage system and a spatial analysis platform will be established. Spatial big data portal and related services using the portal will also be developed.
