RxSpatial: a framework for real-time spatio-temporal operations: demo

Abstract

Existing commercial database systems provide spatial libraries that support functions on static non-moving spatial objects, e.g., points, linestrings and polygons. Examples of these spatial functions include intersection, distance, buffer, and convex hull computation. The RxSpatial, or Reactive Spatial, library provides the same functionality support in the context of moving objects, and addresses the spatial computation challenges over high-frequency, low-latency, real-time moving objects. This demo presents the RxSpatial library that enables developers to instantly compute spatio-temporal operations in an incremental and streaming fashion. The demo scenarios show the applicability of the library in two real-world applications: spatio-temporal social networks and family locators.
