March 2015

In Harm’s Way: Measuring and Mapping Social Vulnerability

March 03, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

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.

Using Spatial Analysis to Assess Flood Risk and Reduction in Coastal Areas

March 24, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

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.

Geospatial Applications in Production Agriculture

April 07, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

Old McDonald may have had a farm, but young McDonald is using technologies that his forebear could only dream about. Many of these technologies focus on variability in the geospatial sense. Whereas site-­specific techniques were formerly employed rather artistically, they are now applied in a scientifically rigorous fashion with automated computer-­based machines.

The Changing Landscape of GIS – A Texas Perspective

April 21, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

Coordination between federal, state, regional, and local governments can make the mapping efforts for Texas extremely challenging. Consistent with the independent characteristics of people important in Texas history, the last 60 years of mapping in Texas state government evolved through the efforts of dedicated individuals who met the challenges head-­on, experienced triumphs and understood the value of lessons learned.

Airborne and Space LiDAR for Forest Inventory

September 10, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

Airborne LiDARs have been used to measure forest canopy characteristics ­e.g., height, canopy density -­‐ for over 30 years. A satellite LiDAR system, ICESat/GLAS, acquired near-­global measurements of canopy heights from 2003-­2007. These systems provide accurate height and density measurements, but their utility for predicting b/c is more limited because the primary driver for predicting biomass is the diameter of a tree, not its height, and not stand density.

Soil Hydrology Across Space and Time – Scale Up and Scale Down

September 24, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

The “Critical Zone” extending from the top of the vegetative canopy through the depth of weathered bedrock plays a central role in Earth’s climate system and provides essential ecosystem services, thereby affecting virtually every aspect of society and the environment. Thus, water stores and fluxes across the critical zone from process scale to management scale are necessary to better account, model, and manage the available water resources.

The Value of Spatial Information and Assessment in Soil, Water and Agricultural Sciences

October 08, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

In soil science, soil development and its association with mass and energy transport, as well as management in agricultural production, has been a highly investigated topic that has included information on soil position in space. In this arena, biophysical models are used to simulate mass and energy fluxes between the soil, plant, and atmosphere and provide a critical link between biological, hydrological and atmospheric disciplines.

Advances in High-­Dimensional Remote Sensing of Vegetation

October 29, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

High-­dimensional remote-­sensing data (e.g., hyperspectral remote-­sensor images) and ancillary geospatial data sets can potentially enable extraction of detailed vegetation­‐type information, as well as more accurate vegetation biophysical parameter estimates, relative to low-­‐dimensional/multispectral data sets. As new sensors become operational, however, improved digital image-processing techniques are needed in order to handle the expected increase in hyperspectral remote-­sensor data volume in a computationally efficient manner.

Bathymetry of Shallow Rivers and Streams Using Hyperspectral Imagery and Multispectral LiDAR

November 05, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

This presentation will give a brief overview of the NCALM facility at the University of Houston. Activities at NCALM pertaining to coastal and fluvial remote sensing will be highlighted, including the use of hyperspectral imagery and bathymetric LiDAR for seagrass mapping, depth determination and turbidity estimation.

Ecometrics Through Space and Time

November 19, 2015
4:00 pm - 5:00 pm
Rudder Tower, Room 301

Ecometrics are trait-­based measurements collected at the community level that relate to climatic, environmental, and ecosystem properties. Ecometrics are documented with modern data from distributions of traits within communities and distributions of abiotic conditions.
