Big Data Hadoop
Segundo artigo recente de 2023:
- Distributed computing frameworks, e.g., SpatialHadoop [18], HadoopGIS [19], and GeoSpark [20], are designed for geospatial data management to leverage the high performance advantage of Hadoop MapReduce and Spark, providing spatial operation and basic spatial models for processing. HadoopViz [21] and GeoSparkViz [22] were developed based on SpatialHadoop and GeoSpark, respectively, for geospatial data visualization. HadoopViz is compatible with SpatialHadoop, and the two are responsible for visualization and data processing, respectively [18]. GeoSparkViz is a scalable spatial data visualization framework with massive data rasterization, pixel aggregation, color rendering and other parallel processing capabilities, and its efficiency can be increased by up to five times [22]. GeoTrellis is also an open-source high-performance geographic data framework developed from Spark, which is capable of processing and visualizing massive amounts of geospatial data
