2017年最后一期公开课预告-《ArcGIS空间大数据平台与Hadoop&Spark大数据平台的集成与开发》
12月26日《ArcGIS空间大数据平台与Hadoop&Spark大数据平台的集成与开发》公开课课程简介：
大数据无疑是近期最时髦的词汇，是继云计算、物联网、移动互联之后，信息技术领域的又一热点；未来十年将是一个“大数据”引领的智慧科技时代，将会给各行业带来根本性变革；占据大数据理论研究和技术应用前沿，将成为在全球新一轮经济发展中赢得竞争优势的关键。
那大数据到底是什么？空间大数据又是什么？主流的大数据技术平台有哪些？ArcGIS空间大数据平台怎么应用？这些高大上的技术又怎么落地到实际的应用中去？
内容概要：
·大数据认知
·地理大数据
·大数据技能体系
·Hadoop&Spark开发模型
·ArcGIS空间大数据平台
·ArcGIS GeoAnalytics Server
·矢量大数据的集成与开发
