PostGIS (/ ˈ p oʊ s t dʒ ɪ s / POST-jis) is an open source software program that adds support for geographic objects to the PostgreSQL object-relational database. PostGIS follows the Simple Features for SQL specification from the Open Geospatial Consortium (OGC). PostGIS is implemented as a PostgreSQL external extension. [2]
uDig is a GIS software program produced by a community led by Canadian-based consulting company Refractions Research. [1] uDig is based on the Eclipse platform and features full layered Open Source GIS. It is written in Java and released under EPL and BSD licences (formerly under GNU LGPL). [2]
Refraction at interface. Many materials have a well-characterized refractive index, but these indices often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers.
In computing, GeoServer is an open-source server written in Java that allows users to share, process and edit geospatial data.Designed for interoperability, it publishes data from any major spatial data source using open standards.
A negative-index metamaterial causes light to refract, or bend, differently than in more common positive-index materials such as glass lenses.. Negative-index metamaterial or negative-index material (NIM) is a metamaterial whose refractive index for an electromagnetic wave has a negative value over some frequency range.
In August 2015 MarketCast acquired the Insight Strategy Group. [11] In August 2017, MarketCast acquired Fizziology, a data analytics company based in Indianapolis, [12] and in 2018 it bought Turnkey Intelligence, a sports research firm. [13] As a result of these four acquisitions MarketCast began to operates through four consumer insights ...
Refraction networking, also known as decoy routing, is a research anti-censorship approach that would allow users to circumvent a censor without using any individual proxy servers. [1] Instead, it implements proxy functionality at the core of partner networks, such as those of Internet service providers , outside the censored country.
Recognizing those who were here before” was displayed in the southwest corner of the first floor. This exhibition, which tells the stories of people, businesses, churches, homes, and community life that once existed in Indianapolis’s near-west side neighborhood prior to university expansion, is part of the IUPUI Welcoming Campus Initiative.
