BigData: Terracotta BigMemory and ArcGIS Webmaps

I was asked to put a Proof of Concept implementation of a very fast interactive dynamic density map generation on 11 million records for a webmap application, where a user can specify dynamically a query definition (a where clause in SQL terms), a ramp color and the service implementation will return back a density representation of the records on a map.This is typically done via a GeoProcessing task...

BigData: DataRush Workflow in ArcMap

At this year's DevSummit, we announced the GIS Tools for Hadoop project. Included in that project is a low level geometry java API which enables spatial operations in MapReduce jobs or the construction of higher level functions such as Hive User Defined Functions. However, this geometry library is not restricted to Hadoop MapReduce. It is used in Geo Event Processor, and can be used in Storm...
