Geographic data sets show two clear trends : they are becoming increasingly abundant and they are growing ever more precise . A variety of massive data sets exhibit an underlying structure that can be modeled as dynamic weighted multi-digraphs . The remaining six ground beef-producing plants without complete data sets range between 18 and 45 samples collected and analyzed by January 25 , 1999 . Our experiments on real-world and synthetic data sets show that transmission costs and communication costs are reduced by upto 6 times and 90 % pruning of queries is achieved when the models are correlated . In another example the complex data provided by ground penetrating radar surveys of buried ancient archaeological sites presents a challenge in the development of advanced computer science techniques for computational inversion , integration , and visualization as well as new methods for dealing with the complex issues of data reduction / collection and modeling that these massive data sets create . Both data sets show similar structure , with Barrow showing much greater variability . These data sets contain detailed information on individual households and individuals including ancestry and place of birth .
