First IQmulus Workshop
The IQmulus Workshop consisted of two keynotes, three presentations discussing a so-called IQmulus contest track and three technical sessions, containing a total of ten technical presentations that were selected based on a submitted extended abstract. The two keynotes presented possible solutions on how to store and respectively process big spatial data. Peter van Oosterom, from Delft University of Technology, gave a keynote presentation entitled Point Cloud Data Management, discussing methodology for storing and querying a huge airborne laser data archive. In his keynote, Mohamed Mokbel, from the University of Minnesota gave an overview entitled Spatial Hadoop: A MapReduce Framework for Spatial Data, of his solution to process big spatial data by explicitly using the spatial locations of the data.
In the following, you will find the titles of the proceedings articles of the first such workshop, including contributions related to the processing contests. The full papers can be read in the Proceedings of the 1st IQmulus Workshop on Processing large geospatial data here.
