How GIS Supports the Fight Against Terrorism

Every incident of terrorism provides a learning curve for the use of GIS and other geospatial technologies in the fight against terrorism. Little empirical work on the spatial and temporal aspects of terrorism exists. So, theoretical models are applied in combination with historical records of terrorists or terror organizations. There is plenty of potential for research, especially in the mashup of technologies that use Big Data and social media activity like tweets to pinpoint location of terrorists; LiDAR and LADAR for 3D mapping and combat operations, geo statistical software for modeling and predictions.

Police versus Waze

Over fifty million users have downloaded Waze.  Waze is a crowdsourcing traffic app that relies on user inputs to tell other users where there are traffic problems such as accidents.  The reporting function of Waze also includes the ability to alert other drivers about speed traps and the location of […]

Using GPS Data to Help Cities in Emergencies

In October of 2012, Hurricane Sandy struck the East Coast of the United States causing billions of dollars in damage. The super storm became the most destructive hurricane of the season but it also provided transportation researchers a new way to analyze the effect that extreme events have on traffic […]

LiDAR: Light Detection And Ranging

LiDAR is an acronym for ‘light’ and ‘radar,’ a tool developed to detect targets and to use reflected light off of objects as a kind of visual sonar. Light Detection And Ranging (LiDAR) can determine how far objects are away from each other by shining a laser onto a target and analyzing the […]

Summer of Maps Fellowship Program

Azavea’s annual Summer of Maps fellowship program is about to open its submission process again.  Summer of Maps is a program that provides $5,000 stipends to GIS students to work as GIS analysts on pro bono geospatial projects for non-profits for a three month period over the summer of 2015. […]
