Big Data - Introduction and Research Topics - for Dutch Kadaster

227

Published on

Presentation (in Dutch) on Big Data (BD) given on Oct 10, 2013 for Dutch Kadaster. To provide an introduction on BD, what could be BD in the geospatial domain, what could be opportunities and research topics for Dutch Kadaster. A personal view, i.e. by no means that this represents opinions or positions of Dutch Kadaster. Just a clarification beyond the buzzword...

  4. 4. Big Data Onderzoek Wat is Big Data? 4 Big data is the term for a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. http://en.wikipedia.org/wiki/Big_data

  6. 6. Big Data Onderzoek Opportunity or Threat? 6 The opportunity of big data is also its challenge. We are drowning in data, and tweets, posts and video are not the structured data that fits well into relational databases for traditional querying. As a result, big data simply requires a new way of thinking about how to store and analyze data to accommodate these new realities and turn insights into actionable decisions. http://www.greenbookblog.org/2012/03/21/big-data-opportunity-or-threat-for-market-research
  7. 7. Big Data Onderzoek Gartner 2012 - 3V’s 7 Big data is high volume, high velocity, and/or high variety information assets that require new forms of processing to enable enhanced decision making, insight discovery and process optimization.

Since much of the data deluge comes from anonymous and unverified sources, it is necessary to establish and flag the quality of the data before it is included in any ensemble. www.geospatialworld.net

  24. 24. Big Data Onderzoek Big Data in Geographic Information Science Panel 2012 24 Big Data is not only big because it involves a huge amount of data, but also because of the high-dimensionality and inter- linkage of the involved data sets. The on-the-fly integration of heterogeneous data from various sources has been named one of the frontiers of Digital Earth research, Bioinformatics, the Digital Humanities, and other emerging research visions. http://stko.geog.ucsb.edu/bigdatagiscience2012
