Efficient Processing of Nearest Surrounder Query for 3D Geospatial Data
The Nearest Surrounder (NS) query is to find a set of all the visible objects that are not obstructed by other objects around the query location. Formally, for a given query Q and dataset D, NS(Q) returns a set of tuples, i i i i O n , , : if and only if (i) Oi Î R and Oi is visible to Q, and (ii) "Oj Î ROi { } , dist Q,Oi ( ) £ dist Q,Oj ( ) at angular range i i , , where i...
متن کاملQuad-Splitting Algorithm for a Window Query on a Hilbert Curve
Space-filling curves, particularly, Hilbert curves, have been extensively used to maintain spatial locality of multi-dimensional data in a wide variety of applications. A window query is an important query operation in spatial (image) databases. Given a Hilbert curve, a window query reports its corresponding orders without the need to decode all the points inside this window into the correspond...
متن کاملA Generalized Query Framework for Geospatial Reasoning
The ability to reason over geospatial entities using publicly available information is greatly enhanced by the abundance of data sources on the Internet. Traditional data sources such as satellite imagery, maps, gazetteers and vector data have long been used in geographic information systems (GIS). However, incorporating non-traditional sources such as phone books and property tax sites brings ...
متن کاملIndexing Query Regions for Streaming Geospatial Data
This paper introduces the Dynamic Cascade Tree (DCT), a structure designed to index query regions on multi-dimensional data streams. The DCT is designed for a stream management system with a particular focus on Remotely-Sensed Imagery (RSI) data streams. For these streams, an important query operation is to efficiently restrict incoming geospatial data to specified regions of interest. As nearl...
متن کاملIncreasing TCP's Initial Window
This document specifies an optional standard for TCP to increase the permitted initial window from one or two segment(s) to roughly 4K bytes, replacing RFC 2414. It discusses the advantages and disadvantages of the higher initial window, and includes discussion of experiments and simulations showing that the higher initial window does not lead to congestion collapse. Finally, this document prov...
