A Review on Spatial Data and Spatial Hadoop

چکیده
Spatial data mining is the process to mine data from spatial data sets like OpenStreetMap or any kind of geographic data. With the emergence of time, Geographic Information get more value from the researchers. This is used to mine useful data and features based on different locations. In related work, existing techniques are based on Dijkstras algorithm and Euclidean distance for spatial data mining. But this is not effective way for spatial data. This data is manipulated by mobile phones, road networks and remote sensing data. In this paper we compare all these techniques to process large data sets of OpenStreetMap.

Study of Spatial Data Quality Elements and VGI Linear Data Quality Assessment Methods
Volunteered Geographic Information has provided a rich and valuable resource for spatial data in a variety of applications. Despite the many benefits, this information does not provide any guarantee for their quality. So far, there are several methods to determine the quality of VGI. In addition to introducing quality elements and their evaluation methods, the present study attempts to explore ...
متن کاملHadoop-GIS: A High Performance Spatial Data Warehousing System over MapReduce
Support of high performance queries on large volumes of spatial data becomes increasingly important in many application domains, including geospatial problems in numerous fields, location based services, and emerging scientific applications that are increasingly data- and compute-intensive. The emergence of massive scale spatial data is due to the proliferation of cost effective and ubiquitous ...
متن کاملThe Impact of Maritime Transportation Instability on International Trade Instability: Combination Spatial Panel data Econometric Approach and Wavelet Smoothing
The main objective of this study is to evaluate the impact of maritime transportation instability on international trade instability based on wavelet smoothing and spatial panel data econometric method during the period 1990-2012. The results showed that the spatial effects have an impact on international trade instability. So that a sudden 100 percent increase in international trade in the nei...
متن کاملSpatial Segregation in Demography: A Short Review
Abstract. Spatial has always been an inherent component of demography, and demographic processes are inherently spatiotemporal. Recognizing the importance of spatial in general and spatial segregation in particular in demographic analysis has created new positions in demography and its conceptual and analytical frameworks. The notion of spatial segregation refers to the distribution of social...
متن کاملSpatio-Temporal Big Data Analytics for Environmental Health
The framework for our proposed big data analytics platform is shown in Figure 1. Two complimentary systems support the wide variety of spatial analytics algorithms and techniques we are providing. On the left half of Figure 1, the more-traditional unix filesystem supports high-throughput computation (e.g., MPI [Snir et al., 1995], OpenMP [Dagum and Menon, 1998], GPGPU/CUDA Luebke et al. [2006])...
