Events for September 9, 2014 - March 24, 2015
September 2014
Space, Place and GIS
Geographers have long recognized the distinction between space and place, and the importance of both, especially the latter, in human geography. GIS, on the other hand, has placed emphasis on space, which is seen as scientifically rigorous and amenable to computation.
Read MoreAirborne and Space-Based Laser Mapping for Earth Science
Over the last two decades with the advancement of laser technology, new mapping techniques and GIS functionality, laser remote sensing has been utilized in many environments to satisfy the need for highly accurate 3-dimensional views of the surface. In fact, the highly accurate data sets collected with airborne laser ranging systems have become the standard for derivation of high-resolution digital elevation models (DEMs) and digital surface models (DSMs) for a growing audience of organizations.

Damage Assessment of Hurricane Flooding A Probabilistic Approach
In this study, we developed an approach for evaluating hurricane flood risk and identify areas that are more prone to it. Flood water elevations were estimated with Surge Response Functions (SRFs), which represent surge values as a function of hurricane parameters (i.e., central pressure, radius, forward speed, approaching angle and landfall location).
Read MoreRemote Sensing Capabilities Using Unmanned Air Systems
Advances in unmanned flight have led to the development of Unmanned Air Systems (UASs) capable of carrying state-of-the-art sensor systems that are useful for a multitude of civil applications such as humanitarian relief (disaster response), precision agriculture (crop monitoring, irrigation, and crop dusting), infrastructure assessment (refineries, roads, bridges, rails, buildings), and resource conservation (forest, desert, oceans, wildlife, forest fires).

The Geospatial Approach: Bridging Science and Community Development
This seminar will showcase case studies from a fisherman village to the Texas border community, from climate change scholars to the agriculture community, from science to inform communities from crime.
Read MoreStatistical Methods for Image Data to Facilitate Geographical Applications
Dr. Jun will discuss parametric covariance functions that can be used to model the spatial and spatio-temporal dependence structure in images and statistical estimation methods for their parameters.

CyberGIS‐Enabled Geospatial Revolution in the Big Data Era
CyberGIS represents an interdisciplinary field synergizing advanced cyberinfrastructure, geographic information science and systems (GIS), spatial analysis and modeling, and a number of geospatial domains to improve research productivity and enable scientific breakthroughs.
Read MoreLiDAR Remote Sensing: Focusing on the Z Coordinate from Ground, Airborne, and Satellite Platforms
Lasers have been one of the greatest scientific developments of the twentieth century. After more than five decades of laser achievements, lasers are still a symbol of high technology and they push the remote sensing field to new “heights.”

In Harm’s Way: Measuring and Mapping Social Vulnerability
Communities are only as strong as their weakest link. They cannot be resilient unless all members are able to withstand and bounce back from an economic, social or physical disaster. Yet, a community’s social vulnerabilities are often neglected. When disaster strikes, its impact is not just a function of its magnitude and where it strikes.
Read MoreUsing Spatial Analysis to Assess Flood Risk and Reduction in Coastal Areas
Never before have the repercussions from both surge and rainfall‐based storm events been so damaging to the economic vitality of local communities. This presentation will demonstrate how spatial analytical techniques can be used to understand the nature of flood risk to coastal residents and identify measures that can reduce flood impacts.
